Always inform your doctor about all medications you are taking, including over-the-counter drugs, supplements, and herbal remedies. Viagra, both 50mg and 100mg doses, can interact negatively with nitrates, often used to treat chest pain. This combination can dangerously lower blood pressure. Avoid using Viagra if you take nitrates.
Specific Medication Interactions
Alpha-blockers, used to treat high blood pressure or enlarged prostate, can also interact with Viagra, potentially causing a significant drop in blood pressure. Similarly, certain antifungal medications, like ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially leading to side effects. Grapefruit juice also inhibits the enzymes that break down Viagra, causing higher blood levels. Avoid grapefruit while taking Viagra.
Other medications that may interact include some protease inhibitors (used to treat HIV), certain antibiotics, and some medications for heart conditions. Your doctor can assess potential interactions and adjust dosages accordingly or suggest alternatives. Open communication with your doctor is crucial for safe and effective Viagra use.
