Always inform your doctor about all medications you take, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra. This is crucial for preventing dangerous interactions.
Nitrates: Combining Viagra with nitrates (found in medications for chest pain like nitroglycerin) can cause a drastic drop in blood pressure, potentially leading to a heart attack or stroke. This combination is strictly prohibited.
Alpha-blockers: These drugs, often prescribed for high blood pressure or enlarged prostate, can also interact negatively with Viagra, causing a significant drop in blood pressure. Your doctor may need to adjust your dosages or choose alternative treatments.
Certain antifungals: Some antifungals, like ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially enhancing its side effects. Close monitoring is necessary.
HIV protease inhibitors: Drugs used to treat HIV can also increase Viagra’s blood levels. Your doctor will determine if dosage adjustments are needed.
Blood thinners: While not a direct contraindication, combining Viagra with blood thinners might increase the risk of bleeding. Discuss this with your physician.
Other medications: Many other medications can interact with Viagra. Always provide a complete list of your medications to your doctor to assess any potential risks.
Never self-adjust your medication dosages. Consult your doctor for any changes or concerns regarding your medications and Viagra.
