Brand Viagra

Brand Viagra is a medicine also known as sildenafil which has been proven to be effective for the treatment of erectile dysfunction. The medication was invented and marketed by Pfizer

How does it work?

The active ingredient of the drug (sildenafil) launches natural mechanisms and stimulates blood flow to the pelvic area and penis. Increased blood flow contributes to the onset of a natural erection. The stimulator will continue to work as long as the man experiences sexual arousal (but no longer than 4-6 hours). After sexual intercourse, the penis returns to a relaxed state.

Indications

The stimulant is designed to treat sexual disorders characterized by the inability to achieve or maintain an erection that is optimal for sexual intercourse. Erection disorders can occur for various reasons – organic, psychogenic, mixed.

How to take Viagra?

To use Viagra, you should understand the mechanism of action of sildenafil. The main condition for the effectiveness of this substance is sexual stimulation. The drug begins to work only in the presence of natural arousal.

Take 1 tablet 50-60 minutes before the intended sexual intercourse. This will allow the main component to have time to absorb in the blood and actively work at the beginning of sex.

The recommended Viagra dosage for men over the age of 18 is 50 mg. In order for the drug to work effectively, it should be taken with a glass of water.

Depending on the indi-vidual characteristics of the body, the doctor can lower or increase the recommended dose of the drug.

The maximum dosage ever prescribed by doctors is 100 mg.

It is not recommended to use the drug no often than once a day. Particular attention should be paid to the fact that the absorption efficiency of the main substance is significantly slowed down when combined with fatty foods.

Taking the drug in combination with alcohol is not recommended.

Side effects

Like any drug, Viagra can cause side effects that are mild / moderate and temporary. Men reported the following side effects:

allergic reaction;
headache, dizziness;
pain in the chest;
nasal congestion;
digestive upset;
skin rash, itching, peeling;
jumps in blood pressure;
prolonged and painful erection;
a sharp decrease or loss of vision.

If you have any disturbing side effect, stop using the stimulant and consult a doctor.

Interactions

Some drugs may change the effect of Viagra. Tell your doctor about any drugs you are taking.

Viagra should never be taken with nitrates;
If you are taking alpha adrenergic blocking drugs to treat hypertension or prostate problems, your blood pressure may drop dramatically. You may feel weak or dizzy;
If you are taking protease inhibitors, you may need a dose correction.

Overdose

If you have an overdose of sildenafil, the frequency of adverse reactions (headache, flushing, dizziness, dyspepsia, nasal congestion, visual impairment) may increase.

Treatment is symptomatic. Hemodialysis is useless.

Precautions

In very rare cases, men reported dizziness and visual impairment after taking sildenafil pills, so you should be careful when driving and operating machinery.

In very rare cases, men reported hearing impairment after taking the drug. If you have a sudden decrease or loss of hearing, stop taking the medicine right away and seek medical advice.

Before using this medicine, you should consult a doctor who will analyze your medical history and perform physical examination. Before starting pharmacological treatment, it is necessary to determine the potential causes of the disease. Before starting treatment for erectile dysfunction, the doctor must assess the condition of the patient’s cardiovascular system, as there is a risk associated with sexual activity.

Sildenafil has vasodilating properties, as a result of which a decrease in blood pressure to a mild or moderate degree may occur. Before prescribing this drug, the doctor should carefully consider the consequences of a possible decrease in blood pressure, especially in combination with sexual activity. Particular attention is required for patients with hypersensitivity to vasodilators (aortic stenosis, hypertrophic obstructive cardiomyopathy), or patients with severe impairment of autonomic blood pressure control.

There is no information on the safety of using Viagra in patients with bleeding disorders or peptic ulcer in the acute stage. Therefore, the drug should be prescribed to these patients only after a careful assessment of the ratio of benefit and risk.

In extremely rare cases, men reported serious cardiovascular complications (including myocardial infarction, unstable angina, sudden coronary death, ventricular arrhythmia, hemorrhagic stroke, transient ischemic attack, arterial hypertension and hypotension) after taking sildenafil. Most of these patients had risk factors for cardiovascular complications. Many of these adverse events were observed shortly after sexual activity, and some of them were noted after taking sildenafil without subsequent sexual activity. It is not possible to establish a direct relationship between these phenomena and the indicated or other factors.
