Viagra, or sildenafil, can interact negatively with certain cardiovascular medications. Always inform your doctor about all medications you are taking, including nitrates (like nitroglycerin) used to treat angina. Combining these can cause a dangerous drop in blood pressure, potentially leading to dizziness, fainting, or even heart attack.
Alpha-blockers, frequently prescribed for high blood pressure or benign prostatic hyperplasia (BPH), may also interact with Viagra, causing a similar, though typically less severe, blood pressure decrease. Your doctor might adjust your dosage of either medication or recommend an alternative.
Certain medications for irregular heartbeats, such as some antiarrhythmics, can potentially interact with Viagra. This interaction varies depending on the specific drug, so always consult your doctor before using Viagra if you’re on heart rhythm medication.
Similarly, if you are on medication to control high blood pressure (hypertension) beyond alpha-blockers, inform your physician before taking Viagra. The combination might lead to hypotension and requires close monitoring.
Finally, discuss your use of Viagra with your doctor if you have any existing heart conditions, including coronary artery disease or heart failure. They will assess your overall health and determine whether Viagra is safe for you.
