About Sildenafil (Viagra)
Sildenafil is a medication prescribed to treat erectile dysfunction (difficulty achieving or maintaining an erection). It is also used to manage pulmonary hypertension (elevated blood pressure in the lung arteries). For Erectile Dysfunction: Sildenafil enhances blood flow to the penis during sexual arousal, facilitating an erection. For Pulmonary Hypertension: It relaxes blood vessels in the chest, improving blood circulation.Brand Names:
Erectile Dysfunction: Viagra, Aronix, Liberize, Nipatra Pulmonary Hypertension: Revatio, Grandipam This medicine requires a prescription but is also available at most pharmacies. It comes in standard tablets, chewable tablets, and an oral liquid solution.Key Facts:
For erectile dysfunction, effects typically begin within 30 to 60 minutes and it can be taken up to 4 hours prior to sexual activity. Sexual arousal is necessary for sildenafil to produce an erection; it does not cause an erection by itself. Headaches, nausea, indigestion, and dizziness are the most frequent side effects, though many users experience none or only mild symptoms. Combining sildenafil with nitrate medications (commonly used for chest pain/angina) is dangerous, as it can cause a severe drop in blood pressure. Consult your doctor or pharmacist if unsure about your medications. Avoid consuming grapefruit juice while taking sildenafil (Revatio) for pulmonary hypertension, as it interferes with the medication's effectiveness.Who Can Take Sildenafil:

Like all medicines, sildenafil can cause side effects, but not everyone experiences them. Common Side Effects (Affecting more than 1 in 100 users): Headaches, nausea, flushing (including hot flushes), indigestion, stuffy nose, dizziness.

If you become pregnant while taking sildenafil for pulmonary hypertension, continue taking it as the risks of untreated pulmonary hypertension are life-threatening. Inform your doctors immediately about the pregnancy; you will require specialized high-risk care throughout.
