Distilled sterile water. What can replace water for injections Indications for use

Water is the most universal solvent, the basis not only for a wide variety of transfusion drugs, but also for biological fluids and tissues (blood, lymph, cell plasma, etc.), necessary for constant metabolic processes.

Under normal conditions, it is excreted in urine, feces, sweat and inhalation. Loss of fluid through sweat, breathing, and feces occurs regardless of fluid administration. Maintaining adequate hydration requires 30-45 ml/kg/day of water in adults, and in children - 45-100 ml/kg, in infants - 100-165 ml/kg.

Water for injection is used for the preparation of infusion and injection solutions, providing optimal conditions for the compatibility and effectiveness of substrates and water. for injection - a hypotonic environment in relation to body tissues, therefore in its pure form it causes slightly more irritation than isotonic solutions or solutions prepared on the basis of water for injection (for parenteral administration, eye drops, etc.). When pure water for injection is injected into a vein, hemolysis may occur, however, slow administration of a small amount has virtually no such effect. Therefore, it is safe for injection as a solvent for drugs (in accordance with the instructions for use) prepared with water for injection.

As a carrier or diluent solution for the preparation of sterile infusion (injection) solutions from powders, lyophilisates and concentrates. It is used for the preparation of sterile solutions intended for subcutaneous, intramuscular or intravenous administration immediately before use.

Externally for washing wounds and moistening dressings.

Water for injection is not used as a solvent for drugs if another solvent is specified as mandatory for some of them.

Intravenously, drip, in the form of “shock” therapy or injection, according to the instructions for the use of added infusion solutions, concentrates, concentrates for preparing infusions, injection solutions, powders and dry matter for preparing injections. The daily dose and rate of infusion should comply with the dosage instructions for the added medications.

Incompatibility of drugs with water practically does not occur, since if a substance is incompatible with water, it will be incompatible with the aquatic environment of the body. When mixed with other drugs (infusion solutions, concentrates for preparing infusions; injection solutions, powders, dry substances for preparing injections), visual control for compatibility is required (chemical or therapeutic incompatibility may occur).

Do not mix oil injection solutions or external cauterization agents with water. Agents whose concentration must remain within certain limits are diluted with water for injection only within the specified limits. for injection cannot be directly injected or administered as an infusion due to the lack of substances with low osmotic pressure (risk of hemolysis!).

Solvent for the preparation of dosage forms for injections 0.5 ml, 1 ml, 2 ml, 3 ml, 5 ml, 10 ml.

10 ampoules in a pack or box along with an ampoule knife or scarifier and instructions for use.

5 ampoules with a capacity of 1 ml and 2 ml in a blister pack. 2 blister packs with a knife or ampoule scarifier and instructions for use in a pack.

5 ampoules with a capacity of 1 ml or 2 ml in a blister pack. 2 blister packs each with instructions for use, an ampoule knife or an ampoule scarifier in a cardboard pack.

When packaging the drug in ampoules with a clamp that has a ring or a point for opening, an ampoule knife or scarifier is not inserted.

1 bottle along with instructions for use in a pack.

Store at a temperature of 5 to 25 °C, out of the reach of children.

Freezing is not allowed.

4 years. Do not use after the expiration date stated on the package.

and as for water for injection, it is ordinary distilled water.

Correctly, they have already told you that, first of all, the difference is in the composition:

• physical solution or saline solution is a 0.9% NaCl solution (salt);
• water for injection does not contain salts or any special substances.

Another difference is that drugs/medicines for IM and SC routes of administration are diluted with water for injection. Phys. the solution is mainly administered intravenously.

If you are going to perform an IV injection, then saline solution is suitable (you can also use glucose, etc.).

If the injection is intramuscular, then there is water for injection, but if the person is sensitive or the drug is painful, then it is better to do it with novocaine.

Phys. the solution is a 0.9% salt solution, it is used to dissolve almost any medication (in other cases, the instructions indicate that it cannot be dissolved with saline, it is indicated what to replace it with) and is suitable for any injections, but intramuscular injections are more painful.

Water for injection is pure salt-free water, so it is less painful for intramuscular injections. It can also be used for any type of injection unless otherwise indicated.

Description of water for injection - composition, instructions for use and shelf life

Many medications intended for injection must first be dissolved or diluted to the desired concentration. For this purpose, a universal solvent is used - water. To be used for medical purposes, it must meet certain requirements. Water for injection, unlike saline solution, which contains sodium chloride, is distilled, sterile water, processed in a certain way.

What is water for injection

Liquid for injection can be used as a carrier of the main drug (parenteral use) or as a diluting agent for infusion and injection solutions with inappropriate concentrations. Water is produced in the form of glass or polymer fiber ampoules of various filling volumes. Intended, among other things, for external use: wetting dressings, washing wounds and mucous membranes. Medical instruments are soaked and washed in injection water during the sterilization process.

Compound

Sterile water has no taste, color or smell. In a special way, the composition of water for injection is cleared of all inclusions: gases, salts, biological components, as well as any microimpurities. This is achieved in two stages. The first is purification by reverse osmosis, during which organic inclusions are separated from water. The second is distillation: the liquid is converted into a vapor state and then returned to its original form. In this way, maximum purity is achieved. Injection water does not have pharmacological activity.

Indications

Used for the preparation of sterile injection solutions from dry matter (powders, concentrates, lyophilisates). Can be used to prepare infusions for subcutaneous, intravenous and intramuscular administration. The dosage and method of administration are determined by the drug to be diluted (the manufacturer prescribes these features in the instructions for the drug). The only universal rule is that water must be used under aseptic conditions from the moment the ampoule is opened until the syringes are filled.

Contraindications

Although water is considered a universal solvent, there are preparations that involve the use of another type of liquid. For example, saline solution, oil solvents, etc. These kinds of features must be prescribed in the instructions for the diluted medicinal product. The injection liquid cannot be mixed with preparations for external use, since they use a different type of solvent.

Requirements for water for injection

The pH value of injection water should not be higher than 5.0-7.0. The concentration of microorganisms in 1 ml is no more than 100. It must be pyrogen-free (devoid of substances that cause an increase in temperature when injecting liquid into the body), with a normalized ammonia content. In water that meets the requirements, the presence of sulfates, chlorides, heavy metals, calcium, nitrates, carbon dioxide and reducing substances is unacceptable.

Instructions for use of water for injection

Doses and rates of administration must comply with the instructions for medical use of the diluted drug. When mixing injection water with powder or concentrate, close visual monitoring of the condition of the resulting liquid should be carried out, since pharmaceutical incompatibility is possible. The appearance of any sediment should be a signal to stop using the mixture. Low osmotic pressure does not allow direct intravascular injection of water - there is a risk of hemolysis.

The shelf life of preparations such as injectable water is no more than 4 years (the release date must be indicated by the manufacturer on the packaging). The storage conditions for the liquid are determined by the temperature range from 5 to 25 degrees. Freezing of the drug is not allowed. After opening the ampoule, it must be used within 24 hours. At the same time, it is stored under sterile conditions. The drug is available in pharmacies by prescription.

What to replace

Often, the injection liquid can be replaced with saline solution or a solution of 0.5% novocaine (used for diluting antibiotics and some physical preparations, the administration of which is accompanied by painful sensations). However, this kind of replacement is permissible only when such a possibility is specified in the instructions for the drug being diluted. If there are no additional recommendations on this matter, you should consult with your pharmacist or your doctor about the possibility of replacing water with other liquids.

What is the best replacement for saline solution for inhalation?

Inhalations are good at clearing the upper respiratory tract of mucus accumulation and saving the mucous membrane from drying out. Previously, steam inhalations were done over boiled potatoes or over a bowl of medicinal herbs. Nowadays, inhalers and medicinal solutions can be used for this procedure. Let's consider the question of how to replace saline solution for inhalation, and how to do it correctly? What compositions for inhalation can you make yourself, with your own hands?

Therapeutic effect of saline solution

Sodium chloride for inhalation is a regular salt solution. It is called physiological because it corresponds to the natural composition of salt in the body. The medicine is diluted with saline solution for injection, because it completely matches the composition of human blood. Each cell of the body contains some sodium chloride for normal functioning.

The saline solution does not cause irritation to the mucous membranes and is perceived by the body as a moisturizing medium. Therefore, inhalation with water for injection is a common method of treatment for colds.

Is it possible to prepare a substitute for saline solution for inhalation yourself? It is possible if you strictly observe the proportions of water and salt. How do pharmacy solutions differ from homemade solutions? They use distilled water. To prepare home inhalation solutions, you can use regular tap water. However, it is pre-filtered to remove unnecessary impurities.

Important! To prepare the inhalation liquid, take 0.9 grams of salt per 100 ml of boiled water. If sediment forms, carefully drain off the clean water.

Is it permissible to use unboiled water? Sometimes adults make solutions without boiling them first, but in inhalations it is safer for children to use boiled water.

How many days can you use the saline solution you prepared yourself, how many times do you inhale? Make a fresh solution every day in the morning, and pour it out in the evening. To accurately weigh salt, you need to use an electronic scale.

Inhalation procedure

How to do saline inhalation correctly? First, cool the prepared liquid to 40 degrees. The procedure should be carried out in between meals. You can breathe through your mouth or nose:

• inhalation through the mouth is done for diseases of the bronchi and lungs;
• Inhalation through the nose is done for respiratory diseases.

Breathing should be smooth and leisurely. When treating pulmonary and bronchial diseases, inhale deeply (all the way), then hold in the air and exhale.

Using a nebulizer

For inhalation with a nebulizer, you can also use a saline solution. If you use a ready-made solution in ampoules, 2 or 5 ml are consumed per procedure. If you bought saline solution in a 200 or 400 ml bottle, use a syringe to pierce the rubber stopper. The liquid must remain in a sealed container, so the rubber stopper must not be opened.

The principle of operation of a nebulizer is based on atomizing liquid to the smallest particles - aerosols. They easily penetrate the lower layers of the respiratory tract, so the use of an inhaler is indicated for diseases of the bronchi and lungs. For respiratory ailments, it is better to use regular steam inhalations.

To use the inhaler solution, you must follow the instructions for it - maintain the dosage accuracy.

Important! The solutions used in the nebulizer should not be oily. This will provoke the development of oil pneumonia.

What formulations can be used for the inhaler? It is allowed to use only saline solution and special liquids, otherwise the device may go out of operating mode. Most nebulizers cannot withstand filling with syrups, decoctions and infusions - they break. If you need a special composition for inhalation, use the steam procedure.

Cough treatment

To get rid of a cough, you need to use antitussive or expectorant preparations. What can replace the saline solution in this case? If a cough accompanies an inflammatory process in the mucous membrane, a saline solution is used together with:

Note! The doctor must prescribe medications and the required dosage.

If there is no ready-made pharmaceutical saline solution, you can use water for injection and alkaline mineral water without gas for inhalation with Berodual. How many times should I inhale? At the beginning of a cold, inhalation is done 3-4 times a day. The device is held in the hands, the mask is put on the nose.

Treatment of a runny nose

For rhinitis, drops and rinsing the nasal passages with saline or just salt water help well. The water should be at room temperature or slightly warmed, but not higher than body temperature, to avoid possible complications.

It is prohibited to inhale:

• at high temperature;
• with purulent and bloody discharge;
• for pain in the ears;
• in a weakened state.

Remember that after inhalation you should not go out onto the balcony or street, or eat for an hour after the procedure.

When should you use a nebulizer, and when should you use a regular steam procedure? A nebulizer is indicated for diseases of the lower respiratory tract; it is useless for rhinitis. Flushing your sinuses with salt water is the way to go. Is it possible to replace saline solution in a nebulizer with oily liquids? No, the device is not designed for oils and syrups. Prepare your own saline solution for the nebulizer or buy ready-made saline solution. To prevent rhinitis, you can use mineral water without gas - Borjomi or Narzan.

How does “water for injection” differ from “saline solution”?

How does “water for injection” differ from “saline solution” or is it the same thing? Is there a difference on what to give injections?

The saline solution contains dissolved salt, which in concentration corresponds to blood plasma. and as for water for injection, it is ordinary distilled water.

As for injections into a vein, you should absolutely not use distilled water; you need to use saline solution.

And for intramuscular administration, both are possible.

The physiological solution contains table salt and its concentration is isotonic to the composition of the blood, it can also be injected into a vein, but water cannot be injected into a vein, because hemolysis will occur, that is, the destruction of red blood cells, and for intramuscular injections there is no big difference, the only intramuscular injection of distilled water is somewhat painful compared to saline solution.

Water for injection is actually water. Distilled.

Saline solution (isotonic), the simplest (one-component) of them is 0.9% NaCl solution (table salt).

Ringer's solution (actually saline solution)

Simply put, a solution of salts present in the blood in the composition and quantity necessary for life, that is, roughly speaking, physiology. Hence the name.

These are just basic saline solutions.

Based on Ringer's solution, even more complex formulations are prepared with the addition of nutrients, antibiotics and antifungal drugs. But this is for intravenous drip administration.

Some drugs can react with salts, losing or changing their properties, which is why water for injection is prepared using double distillation. Information about this must be on the drug packaging or in the attached annotation, if this is critical.

The difference lies in the name itself:

• saline solution is a 0.9% aqueous solution of sodium chloride (NaCl), in other words it is salt and water mixed in certain proportions. The liquid is isotonic to blood plasma. Saline solution can be administered intravenously, subcutaneously, or by enema. It is also used in inhalers and for some other therapeutic and prophylactic purposes.
• water for injection is just sterile water, without any additives. Its composition meets stringent requirements. Unlike saline solution, water for injection is not recommended to be introduced into the body on its own; it is used exclusively for the preparation of solutions for injection from powder, concentrated and some other forms of drugs.

The instructions for the drugs usually indicate the solvent that is acceptable for it, and that is what you should use.

How can you replace water for injections?

Pharmacological action: Anticoagulant, angioprotective,

Pharmacokinetics: 90% is absorbed in the vascular endothelium (creates in

it has a concentration that is several times higher than its concentration in

tissues of other organs) and is absorbed in the small intestine.

Metabolized in the liver and kidneys. Unlike

unfractionated heparin and low molecular weight heparins,

sulodexide is not subject to desulfation, which leads to

decrease in antithrombotic activity and significantly accelerates

elimination from the body. The dose distribution among organs showed

that the drug undergoes extracellular diffusion in the liver and

kidneys 4 hours after administration.

prostacyclin (PGI2), with a decrease in plasma fibrinogen levels

The profibrinolytic effect is due to an increase in blood

level of tissue plasminogen activator and a decrease in the content

The angioprotective effect is associated with the restoration of structural and

functional integrity of vascular endothelial cells, with

restoration of normal negative electrical density

How to properly dilute the antibiotic Ceftriaxone? What solvents to use (novocaine, lidocaine, water for injection) to reduce pain and what quantity is needed to obtain a dosage of 1000 mg, 500 mg and 250 mg for adults and children

In the article we will talk about diluting the antibiotic Ceftriaxone with a solution of Lidocaine 1% and 2% or water for injection for adults and children to obtain the initial dosage of the finished drug solution of 1000 mg, 500 mg or 250 mg. We will also look at what is better to use for diluting the antibiotic - Lidocaine, Novocaine or Water for injection and what better helps relieve pain during the injection of the prepared Ceftriaxone solution.

These questions are the most common, so now there will be a link to this article so as not to be repeated. Everything will be with examples of use.

In all instructions for Ceftriaxone (including drugs under a different name, but with the same composition), 1% Lidocaine is recommended as a solvent.

1% Lidocaine is already contained as a solvent in packages of such drugs as Rosin, Rocephin and others (the active ingredient is Ceftriaxone).

Advantages of Ceftriaxone with solvent in packaging:

• no need to buy a solvent separately (figure out which one);
• the required dose of solvent has already been measured in the ampoule of the solvent, which helps to avoid mistakes when drawing the required amount into the syringe (no need to figure out exactly how much solvent to take);
• in the ampoule with the solvent there is a ready-made solution of 1% lidocaine - there is no need to dilute 2% lidocaine to 1% (it can be difficult to find exactly 1% in pharmacies, you have to dilute it additionally with water for injection).

Disadvantages of Ceftriaxone with a solvent in the package:

• An antibiotic together with a solvent is more expensive (choose what is more important to you - convenience or cost).

How to dilute and inject Ceftriaxone

For intramuscular injection, 500 mg (0.5 g) of the drug should be dissolved in 2 ml (1 ampoule) of a 1% solution of Lidocaine (or for 1000 mg (1 g) of the drug - 3.5 ml of Lidocaine solution (usually 4 ml is used, since this amounts to 2 ampoules of Lidocaine 2 ml each)). It is not recommended to inject more than 1 g of solution into one gluteal muscle.

The dosage of 250 mg (0.25 g) is diluted in the same way as 500 mg (250 mg ampoules did not exist at the time of writing this instruction). That is, 500 mg (0.5 g) of the drug should be dissolved in 2 ml (1 ampoule) of a 1% solution of Lidocaine, and then draw half of the finished solution into two different syringes.

So let's summarize:

1. We obtain 250 mg (0.25 g) of the finished solution as follows:

500 mg (0.5 g) of the drug should be dissolved in 2 ml (1 ampoule) of a 1% solution of Lidocaine and the resulting solution should be drawn into two different syringes (half of the finished solution each).

2. We obtain 500 mg (0.5 g) of the finished solution as follows:

500 mg (0.5 g) of the drug should be dissolved in 2 ml (1 ampoule) of a 1% solution of Lidocaine and draw the resulting solution into 1 syringe.

3. We obtain 1000 mg (1 g) of the finished solution as follows:

1000 mg (1 g) of the drug should be dissolved in 4 ml (2 ampoules) of a 1% solution of Lidocaine and draw the resulting solution into 1 syringe.

How to dilute Ceftriaxone with 2% lidocaine solution

Below is a plate with dilution schemes for the antibiotic Ceftriaxone with a 2% solution of Lidocaine (a 2% solution is found in pharmacies more often than a 1% solution; the dilution method we have already discussed above):

Abbreviations in the table: CEF - Ceftriaxone, R-l - solvent, V injection - water for injection. Below are examples and explanations.

The child was prescribed a course of Ceftriaxone injections twice a day, 500 mg (0.5 g) for 5 days. How many vials of ceftriaxone, ampoules with solvent and syringes will be needed for the entire course of treatment?

If you bought Ceftriaxone 500 mg (0.5 g) (the most convenient option) and Lidocaine 2% at the pharmacy, you will need:

• 10 vials of ceftriaxone;
• 10 ampoules of lidocaine 2%;
• 10 ampoules of water for injection;
• 20 syringes, 2 ml each (2 syringes for each injection - add the solvent with one, draw and inject with the second).

If you bought Ceftriaxone 1000 mg (1.0 g) at the pharmacy (you didn’t find Ceftriaxone 0.5 g) and Lidocaine 2%, you will need:

• 5 vials of Ceftriaxone;
• 5 ampoules Lidocaine 2%
• 5 ampoules of water for injection
• 5 syringes of 5 ml and 10 syringes of 2 ml (3 syringes to prepare 2 injections - add the solvent with one, draw the required volume with the second and third, inject the second immediately, put the third in the refrigerator and inject after 12 hours).

The method is acceptable provided that the solution is prepared for 2 injections at once and the syringe with the solution is stored in the refrigerator (freshly prepared ceftriaxone solutions are physically and chemically stable for 6 hours at room temperature and for 24 hours when stored in the refrigerator at a temperature of 2° to 8°C ).

Disadvantages of this method: injection of an antibiotic after storage in the refrigerator may be more painful; during storage, the solution may change color, which indicates its instability.

The same dosage of Ceftriaxone 1000 mg and Lidocaine 2%, although the regimen is more expensive, but less painful and safer:

• 10 vials of ceftriaxone;
• 10 ampoules of lidocaine 2%;
• 10 ampoules of water for injection;
• 10 syringes of 5 ml and 10 syringes of 2 ml (2 syringes for each injection - one (5 ml) we add the solvent, the second (2 ml) we draw and inject). Half of the resulting solution is drawn into the syringe, the rest is thrown away.

Disadvantage: treatment is more expensive, but freshly prepared solutions are more effective and less painful.

Now popular questions and answers to them.

Why use Lidocaine, Novocaine for diluting Ceftriaxone and why can’t you use water for injection?

To dilute Ceftriaxone to the required concentrations, you can also use water for injection, there are no restrictions, but you need to understand that intramuscular injections of the antibiotic are very painful and if this is done in water (this is what they usually do in hospitals), then it will hurt as much as when injected drug, and for some time after. So it is preferable to use an anesthetic solution as a means for dilution, and use water for injection only as an auxiliary solution when diluting Lidocaine 2%.

There is also a point that it is not possible to use Lidocaine and Novocaine due to the development of allergic reactions to these solutions. Then the option of using water for injection for dilution remains the only possible one. Here you will have to endure pain, since there is a real chance of dying from anaphylactic shock, Quincke's edema, or getting a severe allergic reaction (the same urticaria).

Also, Lidocaine cannot be used for intravenous administration of an antibiotic, only STRICTLY intramuscularly. For intravenous use, the antibiotic must be diluted in water for injection.

What is better to use Novocaine or Lidocaine to dilute the antibiotic?

Novocaine should not be used to dilute Ceftriaxone. This is due to the fact that Novocain reduces the activity of the antibiotic and, in addition, increases the risk of the patient developing a fatal complication - anaphylactic shock.

In addition, according to the observations of the patients themselves, the following can be noted:

• pain during the administration of Ceftriaxone is better relieved by Lidocaine than Novocaine;
• pain during administration may intensify after the administration of not freshly prepared solutions of Ceftriaxone with Novocaine (according to the instructions for the drug, the prepared solution of Ceftriaxone is stable for 6 hours - some patients practice preparing several doses of the Ceftriaxone + Novocaine solution at once to save antibiotic and solvent (for example, solutions of 250 mg of Ceftriaxone from powder 500 mg), otherwise the remainder would have to be thrown away, and for the next injection use a solution or powder from new ampoules).

Is it possible to mix different antibiotics in one syringe, including Ceftriaxone?

Under no circumstances should ceftriaxone solution be mixed with solutions of other antibiotics, because it may crystallize or increase the patient's risk of developing allergic reactions.

How to reduce pain when administering Ceftriaxone?

It is logical from the above - you need to dilute the drug with Lidocaine. In addition, the skill of administering the finished drug also plays an important role (you need to administer it slowly, then there will be little pain).

Can I prescribe an antibiotic myself without consulting a doctor?

If you are guided by the main principle of medicine - Do no harm, then the answer is obvious - NO!

Antibiotics are medications that cannot be dosed or prescribed yourself, without consulting a specialist. Since choosing an antibiotic based on the advice of friends or on the Internet, we thereby narrow the field of activity for doctors who can treat the consequences or complications of your disease. That is, the antibiotic did not work (it was injected or diluted incorrectly, it was taken incorrectly), but it was good, and since the bacteria are already accustomed to it as a result of the incorrect treatment regimen, you will have to prescribe a more expensive backup antibiotic, which, after incorrect previous treatment, will also help unknown whether. So the situation is clear - you need to go to the doctor for a prescription and appointment.

Also, allergy sufferers (ideally, again, all patients who are taking this drug for the first time) are also advised to prescribe scratch tests to determine an allergic reaction to prescribed antibiotics.

Also, ideally, it is necessary to inoculate biological fluids and human tissues and determine the sensitivity of the inoculated bacteria to antibiotics so that the prescription of a particular drug is justified.

I would like to believe that after the appearance of this article in the Directory, there will be fewer questions on the methods and dilution schemes for the antibiotic Ceftriaxone, since I have analyzed the main points and schemes here, all that remains is to read carefully.

Typical clinical and pharmacological article 1

Characteristic. Sterile, pyrogen-free, colorless, odorless, tasteless, transparent liquid that does not contain chemical, especially toxic, impurities (nitrates, nitrites, chlorides, sulfates, heavy metals, etc.).

Pharmaceutical action. Solvent. In the human body, water is necessary for constant metabolic processes. Under normal conditions, water is excreted through urine, feces, sweat, and breathing. Loss of fluid through sweat, breathing, and feces occurs regardless of fluid administration. Maintaining adequate hydration requires 30-45 ml/kg/day of water in adults, and in children - 45-100 ml/kg, in infants - 100-165 ml/kg. Water for injection is used for the preparation of infusion and injection solutions, providing optimal conditions for the compatibility and effectiveness of substrates and water.

Pharmacokinetics. With the introduction of constantly alternating water and electrolytes, homeostasis is maintained by the kidneys.

Indications. As a carrier or diluent solution for the preparation of sterile infusion (injection) solutions from powders, lyophilisates and concentrates. Used for the preparation of sterile solutions, incl. for subcutaneous, intramuscular, intravenous administration. Externally for washing wounds and moistening dressings.

Contraindications. If another solvent is specified for the preparation of the drug.

Dosing. The dose and rate of administration must comply with the dosage instructions for diluted drugs.

Preparation of drug solutions using water for injection must be carried out under sterile conditions (opening ampoules, filling syringes and containers with drugs).

Interaction. When mixed with other drugs (infusion solutions, concentrates for preparing infusions; injection solutions, powders, dry substances for preparing injections), visual control for compatibility is required (pharmaceutical incompatibility may occur).

Special instructions. Water for injection cannot be directly administered intravascularly due to low osmotic pressure (risk of hemolysis!).
