What day does Viagra start working? Viagra preparation: description, scheme of application and side effects

Contraceptive pills have a completely understandable effect, they serve as one of the most reliable types of contraception. Modern drugs There are two types, the first consist of one hormone - progestogen, and the second of two hormones - estradiol (estrogen) and progestogen. At the same time, the former are recommended for women who are breastfeeding and over the age of 35, especially those who have such a bad habit as smoking. And the latter are considered the drugs of first choice, they are prescribed to most women, since the effect of the tablets is the most physiological. Yes and side effects they cause less than pure gestagenic ones. But let's talk about everything in order.

Undoubtedly, in the first place, the effectiveness of the drug is explained precisely by the gestagen. In most cases, it suppresses ovulation or leads to insufficiency of the second phase of the cycle, corpus luteum produces very little progesterone, and the implantation and development of a fertilized egg becomes impossible. But you should not worry, the effect of birth control pills in the vast majority of cases is reversible. That is, immediately or almost immediately after discontinuation of the drug with menstrual cycle the woman will be all right if there are no other problems.

The second hormone, estrogen, prevents the development dominant follicle and also warns premature detachment endometrium. That helps to avoid intermenstrual discharge. Although sometimes the principle of action of hormonal contraceptive pills fails, and the body needs to get used to hormonal contraceptive. This adjustment period usually lasts up to three months. If the given side effect lasts longer, you need to change the drug. Doctors usually recommend a contraceptive with great content estrogen. For example, instead of 20 mcg - 30 mcg. Thus, "Logest" can be replaced by "Janine" or "Lindinet 30". Such a recommendation is usually made if intermenstrual discharge is observed from about 10-12 days, in the middle of the cycle.

When do birth control pills start working, on what day do they become effective? If a woman started taking the first package of the drug as required by the instructions, that is, from the first day of the cycle, then they work immediately. If the reception is started, say, from the fifth day, then the first 7-14 days should be additionally protected, preferably with condoms. This is the answer to the question of when you can not protect yourself after starting taking birth control pills without fear of becoming pregnant. By the way, contraceptive effect the drug is retained in seven day break in his reception, during which menstruation begins. It turns out that's how they work birth control pills during this time period - a woman does not accept them, but is reliably protected from unwanted pregnancy. This is the so-called barren period, when a woman cannot conceive even outside the pills. This knowledge is used in the protection calendar method. But he, of course, is much less reliable than hormonal contraceptives.

Doctors are often asked what is the probability that the effect of taking Viagra will not suddenly disappear at the right time. This question is quite relevant for many men, because confidence in the possibility of a full-fledged sexual intercourse is a guarantee good relations between lovers. Doctors do not give an unequivocal answer, since the duration of the influence of the main component of the drug on the body depends on many factors. Therefore, in order not to fall into awkward situation, experts advise to get acquainted with the features of Viagra and recommendations for its use.

The composition of the drug includes sildenafil citrate, which enhances the body's response to sexual stimulation. This is due to the fact that the active substance blocks enzymes that reduce the biosynthesis of nitric oxide, and this, in turn, contributes to the expansion of cavernous tissues and an increase in blood flow to the penis at the time of arousal.

Sildenafil promotes the release of nitric oxide in the blood;
Expands blood vessels;
Enhances blood flow to cavernous bodies penis;
Relaxes smooth muscle small pelvis.

So, when taking Viagra, 95% of men achieve. It is important to know that an erection stimulator will not be effective without full stimulation of arousal. Therefore, the drug does not affect the male libido, the psyche. Therefore, without the desire for sex, there will be no erection.

How long does Viagra take to work?

As a rule, a Viagra tablet is available in a dosage of 100 mg. it average dose which is most commonly assigned. But, in pharmacies you can find 25, 50 and 150 mg of sildenafil. Therefore, the time of onset of erection after taking the drug depends on the dosage, the individual characteristics of the male body. There is no exact time period.

If a man takes a 100 mg tablet, a full erection will occur 20-50 minutes after consumption. Some representatives of the stronger sex, with strong arousal, note the onset of an erection after 15 minutes. Sildenafil is quite easily and quickly absorbed into the blood. But, for maximum quick effect We recommend following simple rules:

Take a Viagra tablet on an empty stomach. Instructions for use of the drug indicates that the medicine can be taken regardless of food. But, fatty foods can reduce the absorption of the active substance. Therefore, the effect of the remedy will be weaker. If you do not adhere to this rule, the action may occur after 2 hours.
In order for the action of the pathogen to come very quickly, the tablet is washed down with plenty of water.

It is worth checking the speed of action with the minimum dosage. So, for starters, a man is prescribed 50 mg of sildenafil. You need to drink a pill 40 minutes before the intended sexual intercourse. If the drug acts quickly, and the erection is stable, this dosage is enough. Depending on the age and the presence of chronic diseases, the dose of Viagra will decrease or increase.

Do not recommend combining Viagra with alcohol. Alcoholic beverages can reduce the speed of action of the tablets. Also, a large amount of alcohol reduces the sensitivity of the genitals, and consequently, the erection will be weak. You can use the stimulant 1 time per knock. If you use the medicine more often, sildenafil will have the opposite effect - there will be no erection at all. An increase in the dosage of the drug can provoke the development of priapism.

Much depends on the age, body weight of a young person. Numerous reviews indicate that Viagra retains its maximum action within 4-5 hours. 2 hours after taking the pathogen, the decline in efficiency begins.

Also, there are cases when the action of the pathogen persists all night. During this period, a man can have sexual intercourse. The erection disappears, as always, after the process of ejaculation. But, you can not abuse the drug. It's better to use it in extreme cases. Otherwise, the body will develop addiction, and the effect of the pill will be ineffective.

There are some myths about the action of Viagra that are not supported by medical research:

Sildenafil provokes excessive long erection. Taking Viagra very rarely provokes priapism - only if the male body is predisposed to this. After ejaculation, the penis gradually comes to a calm state.
The rapid action of Viagra leads to painful sensations during strong erection. The action of the stimulant occurs gradually, during the first half hour after administration. Sharp increase erection does not occur. Therefore, pain in the penis, scrotum should not be.

Persistent, full-fledged erection from taking Viagra Soft is observed within 4 hours. The most effective, with a long period of action is Royal Viagra. Thanks to its natural basis, just 1 tablet of the product provides a full erection for 1 week. Therefore, taking this drug is permissible no more than 1 time in 7 days.
