Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection. This effect stems from Viagra’s inhibition of an enzyme called phosphodiesterase-5 (PDE5).

Dosage: Your doctor will determine the appropriate dosage, typically starting with 50mg. Adjustments may be needed based on individual responses and potential side effects.

Important Considerations: Viagra isn’t suitable for everyone. Men with heart problems, low blood pressure, or specific eye conditions should consult their physician before use. Interactions with other medications are possible. Always disclose all medications you are taking.

Beyond ED: While primarily used for ED, Viagra also finds application in treating pulmonary arterial hypertension (PAH), a condition affecting blood vessels in the lungs. This use leverages Viagra’s ability to relax blood vessels, improving blood flow.

Side Effects: Common side effects include headaches, flushing, nasal congestion, and visual disturbances. Less common, but more serious, side effects necessitate immediate medical attention. Consult your doctor about any concerns.

Seeking Professional Help: If you experience ED or PAH, a consultation with a doctor is paramount. They will assess your health and determine if Viagra is an appropriate treatment option.
