Viagra

Viagra is one of the most effective and popular preparations for the treatment of erectile dysfunction symptoms. It helps to improve the symptoms of erectile dysfunction, thus providing men with a firm and lasting erection, which is enough for performing sexual intercourse.

The active ingredient is sildenafil. By placing an order, you confirm that you have knowledge of what sildenafil is and are familiar with its correct dosing regimen. We recommend getting a consultation with a doctor first and seek immediate medical help in case you develop any side effects to the drug.

What is Viagra?

Viagra is a medication belonging to the class of PDE5 inhibitors. It acts by relaxing the smooth muscles of the cavernous bodies of the penis and widening the penile blood vessels. Due to this, the organ can be filled with sufficient amount of blood to guarantee a strong and durable erection. The effect of sildenafil can be noticed only when a man gets adequate sexual stimulation and feels sexual arousal. Otherwise, the effect will be absent. Such a property of the drug makes an erection look absolutely natural so the partner won’t know about your problem.

Viagra dosage and administration

To determine the right dosing regimen, it is important to consult a doctor because every case is unique. The recommended starting dose of sildenafil is 50mg about an hour before sexual activity. However, the drug can already start acting in 30 minutes. A high-fat meal will delay Tmax of sildenafil concentration in plasma for up to 60 minutes. So it is better to take the pill on an empty stomach with a full glass of water.

If the effectiveness of the tablet is low, the dose can be increased to 100mg, yet it is the maximum safe dose recommended per 24 hours. On the contrary, when the result is too strong or you have experienced any adverse reactions, the dosage may be reduced to 25mg. Men over 65 are commonly advised to start with 25mg as their risks for side effects are higher.

Interaction with other drugs

Before you start using Viagra, inform your medical specialist about the drugs you currently take as some of them can dangerously interact with sildenafil. They are as follows:

• Nitrate drugs;
• Recreational drugs “poppers ”;
• Alpha-blockers;

That’s why this medication should be applied with caution in patients with some underlying medical conditions (e.g. elevated blood pressure, diabetes, etc.).

Elderly patients and individuals having kidneys or liver disease may need their dose to be adjusted based on their health condition.
