Viagra, containing sildenafil citrate, primarily treats erectile dysfunction (ED). It enhances blood flow to the penis, enabling men to achieve and maintain an erection firm enough for satisfactory sexual intercourse. This improved blood flow is the key mechanism of action.
Beyond ED, Viagra also demonstrates efficacy in treating pulmonary arterial hypertension (PAH). By relaxing blood vessels in the lungs, it improves blood flow and reduces strain on the heart. This application showcases Viagra’s broader impact on circulatory health. Remember to consult a doctor before using Viagra for either condition, as it’s a prescription medication.
Dosage varies based on individual needs and medical history; your physician will determine the appropriate amount. Side effects, though generally mild, can include headaches, flushing, and nasal congestion. Always inform your doctor about existing health conditions or medications you take to ensure safe usage and avoid potential drug interactions. Proper medical guidance is paramount for safe and effective treatment.
