Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra. Certain medications can interact negatively with Viagra, potentially leading to adverse effects.
Nitrates, commonly used to treat chest pain (angina), are a significant concern. Combining nitrates and Viagra can cause a dangerous drop in blood pressure, potentially leading to dizziness, fainting, or even heart attack. Avoid using Viagra if you take nitrates.
Alpha-blockers, prescribed for high blood pressure or enlarged prostate, can also interact with Viagra, causing a similar blood pressure drop. Your doctor may adjust your dosage or suggest an alternative.
Certain antifungals, such as ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially leading to side effects. Your doctor might lower your Viagra dose.
Drugs affecting liver enzymes, such as erythromycin and cimetidine, may also interact with Viagra’s metabolism. Dosage adjustments are possible.
Taking Viagra with protease inhibitors, used to treat HIV, can also elevate Viagra’s blood levels. Close monitoring is recommended.
This information isn’t exhaustive. Discuss all your medications with your doctor or pharmacist to ensure safe and effective Viagra use. They can assess potential interactions and help you make informed decisions about your treatment.
