After what time and for how long does the medicine take effect?
Viagra tablets have an effect within half an hour after administration. Average action time is 4-5 hours. However, this period can vary more or less. The cause of the deviation may be the weight and constitution of the man, the characteristics of the digestive system and the body as a whole.
A heavy, fatty meal eaten shortly before taking the pill will weaken the effect of the drug, and an empty stomach will enhance it. The maximum effect of the tablet occurs 1.5 hours after administration. Viagra should not be taken with alcoholic beverages, as this may negate the expected result.
In what form is Viagra available?
Viagra is produced and sold exclusively in tablet form. Any liquid options, injections or suspensions are fake.
The drug is packaged in blisters with different numbers of tablets, according to:
- 1 piece;
- 2 pieces;
- 4 pieces;
- 12 pieces;
Each tablet is coated with a blue varnish film shell. It has a diamond shape with rounded tops and clear edges. A blister with any quantity is placed in a cardboard package, on which there is a control confirming that it has not been opened.
How did Viagra come about?
In the early 90s, the American people were developing an effective medicine for people suffering from angina pectoris, which could effectively relieve pain. The main active component of the tablets was sildenafil. During testing on volunteers, employees received information from men that the drug significantly improved the quality of their sex life, despite the fact that it had no effect on the manifestations of cardiac pathology.
When the experimental group of men flatly refused to return the pills, which were useless for angina, at the end of the study, the employees fully realized that they had unexpectedly created an innovative product, which they gave the name “Viagra.” Translated, it sounds like “the power of Niagara Falls.”
Additional studies of the drug conducted in 1993 proved not only its effectiveness in stimulating an erection, but also its complete safety. From that moment on, Viagra began to quickly spread throughout the world and conquer it.
It is important to know! “Do you want powerful potency and a lasting erection, without any side effects on the cardiovascular system?! The drug is suitable for men of any age...” Read more…
When does Viagra not work?
The use of Viagra will be pointless if the difficulties of sexual intercourse are not associated with insufficient blood filling of the penis, but have other reasons, for example:
- penis injuries;
- too narrow gaps in the arteries of the penis;
- lack of libido or mechanical stimulation of the penis;
- individual immunity to sildenafil.
It happens that the first time Viagra does not give the expected effect, so if something goes wrong right away, it’s too early to despair. It might be worth trying again. Its effect weakens if the level of testosterone in the blood is too low or the man experienced severe stress the day before.
You need to understand that Viagra is not an aphrodisiac or stimulant. If a man has no desire for sexual intercourse, then the effect of taking a pill of this drug does not guarantee sexual arousal. In addition, stimulation is necessary for arousal to occur. If you take Viagra and watch TV, the results will not appear.
Impact on the psyche, or why Viagra is needed by healthy men
Viagra is taken by many men who do not suffer from erectile dysfunction. What does taking the drug give them against the background of apparent well-being:
- Satisfying interest . Everyone wants to experience at least once the effects of a world-famous brand.
- Psychological safety net . Men are very afraid of being unsuccessful in bed, especially if this is the first contact or a new partner. Excessive sexual arousal can cause fiasco. Viagra is taken to prevent embarrassment.
- A different perception . Thanks to the use of the drug, the sensitivity of the penis, especially its head, may become aggravated, which is a consequence of strong filling and a powerful erection.
By and large, men who do not have sexual difficulties do not gain anything physically from taking Viagra. However, if the pills significantly improve the quality of potency, this is a signal of impending problems and a reason to consult a doctor.
Indications for use
Viagra is effective for erectile dysfunction, which is caused by poor filling of the penis with blood, which is why it cannot acquire the necessary hardness to ensure normal insertion into the partner’s vagina and friction. Such disorders are often caused by:
- atherosclerosis;
- varicose veins;
- diabetes mellitus;
- nervous disorders;
- circulatory disorders;
- spinal injuries;
- high blood viscosity.
If difficulties with full sexual intercourse are associated with one of the listed reasons, then Viagra becomes a real salvation for restoring potency. In addition, the use of these tablets allows you to remove the psychological negative consequences of male incompetence.
Many men who experience difficulties of a sexual nature often fall into the blues and begin to consider themselves inferior, out of print, which only aggravates the situation and complicates treatment. In some cases, having eliminated the physiological basis of erectile dysfunction, they then have to turn to the services of psychotherapists. With the help of Viagra, this situation can be avoided.
Manifestation of side effects
The drug is sold in the public domain and does not require a doctor's prescription to purchase, however, Viagra is still a medicine and it is advisable to consult a urologist or therapist before starting to take it. This is especially true for men taking nitroglycerin and other heart medications. Viagra is incompatible with a number of drugs in this group.
Numerous studies have confirmed its safety and the absence of subsequent dependence, but in rare episodes the drug can still cause unwanted reactions in the form of:
- Headaches;
- Tides;
- Fever;
- Diarrhea;
- Swelling of the nose;
- Arrhythmias;
- Visual impairment;
In the 25 years that Viagra has been sold worldwide, fewer than 100 deaths have been reported. And even then, they cannot be attributed to the use of the drug, since the victims had a history of heart pathologies and it was not possible to prove that Viagra was the cause of their death in any case.
Contraindications
The drug is not indicated for use by minors. It is not advisable for men who have:
- Ischemia;
- Previous heart attacks and strokes (including micro);
- Myeloma;
- Anemia;
- Aggravated stomach ulcer;
- Thrombosis;
- Uncontrolled hypotension;
- Heart failure;
- Angina pectoris.
Women should not take Viagra tablets; it will not have the same effect on men. For ladies, there are drugs that are similar in action, but are designed for the nuances of the female body.
Today Viagra is the leader in sales in this niche. Its developers were awarded the Nobel Prize for their accidental discovery back in 1998. Since the advent of these pills, the lives of millions of men have changed for the better.
The active ingredient in this product is
Sildenafil, which is part of the tablet, does not directly cause muscle relaxation, but under its influence the effect of nitric oxide is enhanced. The principle of action of Viagra is based precisely on this.
In addition to it, Viagra contains auxiliary components:
- cellulose;
- calcium hydrogen phosphate;
- magnesium stearate;
- sodium croscarmellose.
These substances are necessary for the drug to be fully absorbed by the body and give the desired effect.
