What other drugs will affect sildenafil?
If you have severe heart conditions (such as a recent heart attack or stroke) or liver disease, this medication could worsen your condition. Low blood pressure (hypotension): Sildenafil can lower your blood pressure further, which could lead to dizziness, fainting, or even a dangerous drop in blood pressure. Recent stroke or heart attack: If you’ve had a stroke or heart attack within the last 6 months, Sildenafil may increase your risk of another cardiovascular event due to its effects on blood flow and blood pressure. Use of nitrates: Nitrates (often used for chest pain) and Sildenafil both lower blood pressure. Taking them together can cause a significant and dangerous drop in blood pressure. Heart failure: Medications like beta-blockers, ACE inhibitors, or diuretics may be used. Lifestyle changes, such as reducing salt intake, exercising regularly, and managing stress, are also important.
