Frequently Asked Questions
What Are The Benefits of Viagra?
Viagra is one of the most convenient treatments for erectile dysfunction. It becomes effective in just 30 minutes after taking and allows you to have a natural erection for up to 4 hours.
Viagra has been seen to successfully treat the problem of impotence in more men than both Levitra and Cialis. The active ingredient of Viagra, Sildenafil Citrate, improves overall sexual activity by increasing blood flow to the penis and thus solves the problem of impotence.
cGMP, a naturally occurring nucleotide substance in your body, is responsible for relaxing the muscle walls of the penis and increase the blood flow to it , which results in an erection.
How Does Viagra Work?
An enzyme called PDE-5 is responsible for breaking down cGMP once an erection is achieved. When there is an excess of PDE-5 in your body, it restricts blood flow to the penis and keeps it flaccid even when you are sexually aroused.
The active ingredient of Viagra, Sildenafil, inhibits this enzyme PDE-5 which allows the blood vessels to relax for longer and increase the blood flow to the penis. As a result of this, the person can achieve a more potent and longer-lasting erection when sexually aroused.
How Long Does It Take For Viagra To Work?
Viagra (Sildenafil) significantly increases the quality of an erection and the time of intercourse. The drug starts working in about 30 minutes after taking it and remains active for about an hour.
How Long Does Viagra Last?
It is hard to determine the exact time of Viagra’s action because each person reacts differently to Sildenafil. Much depends on a person’s age, his physical shape, gastrointestinal tract health, and other factors.
On average, Viagra works for 4 hours with a gradual decrease in the effect after 2 hours. However, there are cases when sexual power is maintained throughout the night. In other words, it is purely individual how long Viagra acts for each person.
Who Can Take Viagra?
Men who are above the age of 18 years and are suffering from the frequent problem of erectile dysfunction can request Viagra medication to improve their sexual health.
However, avoid taking the drug along with certain treatments or if you are suffering from certain conditions like:
- Heart problem
- Recent stroke
- Problem of liver function
- Low blood pressure
- Rare hereditary problems of galactose intolerance
- Genetic degeneration of the back of the eyeball
Thus, it is crucial to answering all the questions in online consultation in as much detail as possible.
How To Take Viagra?
You can take one tablet of Viagra up-to once a day without any contraindications. Take the blue pill 30 minutes before you intend to have sexual intercourse.
The available dosages are: 25mg, 50mg and 100mg. If you are buying this medication for the first time, start with the smaller dose, then increase it if necessary to obtain better results.
It is important to always stick to the Viagra dosage prescribed to you by the doctor.
Keep in mind that eating fatty foods or using alcohol can prevent Viagra from functioning properly and producing desired results.
What Are The Side Effects?

The genuine Viagra by Pfizer is considered to be safe in most cases. However, like any other drug, it may have certain side effects.
Some of the most common side effects reported in 1 of 10 men include headaches, nasal congestion, and mild stomach upset after meals. Mos of these adverse reaction will disappear shortly.
Other less common side effects of Viagra are:
- Abnormal vision
- Distorted color perception
- Sensitivity to light
- Dark or reddish urine
- Diarrhea
Viagra is a safe drug, but it is not suitable for all conditions and all people. Individuals with heart and liver problems, taking nitrates, or recently suffered a stroke and heart attack should avoid using Viagra.
What Are The Precautions?
Avoid using similar substances within the next 24 hours after taking 1 pill of Viagra. You should not use Viagra at all if you:
- Use other nitrogen donators. Athletes very often use them during training. Remember, if you are using another nitrogen donor, you do not need the potency enhancer.
- Use steroids. Steroids improve the synthesis and cellular perception of Viagra. In this case, take Sildenafil in a half dose or do not take it at all.
- Abuse of alcohol. Of course, a glass or two of wine at a romantic dinner will not significantly affect your health. But big doses of alcohol together with Viagra can lead to severe consequences up to a heart attack.
- Take blood pressure medication. Sexual activity poses some risk if you have heart disease.
What Happens If A Woman Takes Viagra?
The drug label states that Viagra is prescribed exclusively for men. The effect on the circulatory system and stimulation of blood flow to the genitals during intimacy is the same for both men and women.
Therefore, we can only speculate how the pill will act on a woman and stimulate the blood flow to the pelvic organs, improving the quality of intimacy.
However, there is no reliable research in this area. That is why we should not abuse and experiment, because there is a wide choice of special products on the market that can solve specifically female sexual problems.
