Generic Sildenafil

Viagra has sildenafil citrate as its main component. The drug helps the release of nitric oxide in the penile muscular tissue, thus promoting its relaxation. The same reaction takes place in the penile blood vessels. As a result, they expand and enhance the inflow of blood to the penis, which is the key to a firm and durable erection. The described mechanism is triggered by sexual stimulation. If it is not sufficient or absent, there will be no reaction to the drug. The effect lasts for about 4-5 hours.

Brand Viagra tablets are produced in three strengths: 25mg, 50mg, and 100mg of sildenafil in one pill. If there are no serious health issues, doctors usually recommend starting the treatment with a 50mg dose. Based on the response and individual tolerance to the drug, the dose can be titrated to 25mg (if the initial one has been too strong) or to 100mg (if you’ve lacked the effect).

Brand Viagra should be taken only when needed. The shortest period between two pills intake should be not less than 24 hours. 100mg/day is the highest safe dose. The tablet should be taken about 30-60 minutes before sexual activity. If the drug is taken with food, the onset of action can be delayed.

Sildenafil, if taken with other drugs, can dangerously interact with some of them. Avoid concomitant intake of brand Viagra with:
 Ketoconazole, itraconazole;
 Nitrate drugs (e.g. nitroglycerin);
 Amlodipine;
 Ritonavir, indinavir, and other HIV-protease inhibitors;
 Riociguat;
 Alpha-blockers (unless you are stable on them);
 Clarithromycin, erythromycin, and some more antibiotics. This list can be continued, so consult a specialist concerning the safety of Viagra interaction with the drugs you currently use.

You should obligatorily inform your healthcare provider if you have or have had any of the following health conditions:
 Heart disease;
 Liver dysfunction;
 Kidneys disease;
 Stomach ulcer;
 Deformations of the penis;
 Scarring on the penis;

Brand Viagra is well-tolerated by the bulk of its users. However, it may provoke some light unwanted effects that go away on their own and don’t need medical attention. They are:  Flushing;  Diarrhea;  Nasal congestion;  Headache;  Pain in the muscles or back pain. Besides, in some patients, there may evolve dizziness, stomachache, troubles with vision, chest pain, partial or complete hearing loss. Experiencing any of the mentioned reactions reach for medical help.

The symptoms of an overdose are the same as those experienced during therapeutic dose intake. But the incidence and the rate of side effects severity may be higher. Turn for medical help if brand Viagra overdose happened. There is not any possibility to miss the dose as Brand Viagra is not for daily intake.

No toxic effect on the human organism has been revealed if the medication is taken as prescribed by a doctor.
