Always inform your doctor about all medications you take, including over-the-counter drugs and supplements, before starting Viagra. This is particularly crucial if you have a history of stroke or heart problems.
Certain medications significantly increase the risk of adverse interactions with Viagra. These include nitrates (used for angina), alpha-blockers (used for high blood pressure and prostate problems), and some antifungals.
Combining Viagra with nitrates can cause a dangerous drop in blood pressure, potentially leading to fainting or even a heart attack. Similarly, concurrent use with alpha-blockers can severely lower blood pressure.
Specific antifungals, like ketoconazole and itraconazole, can increase Viagra’s concentration in the blood, raising the risk of side effects.
Here’s a table summarizing some key interactions:
| Nitrates | Nitroglycerin, isosorbide mononitrate | Severe blood pressure drop |
| Alpha-blockers | Terazosin, tamsulosin | Significant blood pressure decrease |
| Antifungals (Azoles) | Ketoconazole, itraconazole | Increased Viagra blood levels, heightened side effects |
Your physician will assess your individual medical history and medication profile to determine if Viagra is safe for you. Never take Viagra without a doctor’s prescription and always adhere to the prescribed dosage.
