Sildenafil citrate, the active ingredient in Viagra, primarily treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for firmer erections suitable for sexual activity.
Beyond ED, sildenafil also effectively treats pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. It helps relax and widen these blood vessels, improving blood flow and reducing strain on the heart.
Dosage for ED varies depending on individual needs and response, typically ranging from 25mg to 100mg. For PAH, doctors prescribe different dosages based on the severity of the condition and patient’s response to treatment.
While generally safe, sildenafil can interact with certain medications, notably nitrates used to treat angina. Consult your doctor before using sildenafil if you are on other medications. Potential side effects include headache, flushing, nasal congestion, and visual disturbances; these are usually mild and temporary. Serious side effects are rare.
Always obtain sildenafil from a reputable source and follow your doctor’s instructions carefully. Improper use can lead to health complications.
