Interactions with Other Medications and Substances

Always inform your doctor about all medications, supplements, and herbal remedies you take, including over-the-counter drugs. This includes nitrates, often used for chest pain, as combining them with Viagra can cause a dangerous drop in blood pressure. Alpha-blockers, commonly prescribed for high blood pressure or prostate problems, may also interact, potentially leading to dizziness or fainting.

Specific Interactions to Note

Certain antifungals, like ketoconazole and itraconazole, can increase Viagra’s concentration in your bloodstream, potentially increasing side effects. Similarly, some HIV protease inhibitors can have the same effect. Grapefruit juice can also interfere with Viagra’s metabolism, raising its levels and risks. Avoid alcohol consumption while taking Viagra, as it can worsen side effects such as headaches and dizziness.

This information is not exhaustive. Consult your physician or pharmacist for a complete list of potential interactions and personalized advice before starting or continuing Viagra. They can assess your individual health status and medication history to determine any potential risks. Your safety is paramount.
