Interactions with Other Medications

Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra. This includes nitrates, often used for chest pain. Combining Viagra with nitrates can cause a dangerous drop in blood pressure.

Alpha-blockers, commonly prescribed for high blood pressure or enlarged prostate, can also interact with Viagra, potentially leading to low blood pressure. Your doctor may adjust your dosages or recommend alternatives.

Certain antifungal medications, such as ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially enhancing its effects and side effects. Your doctor might lower your Viagra dose.

HIV protease inhibitors, used to treat HIV, can also interact with Viagra, similarly increasing its concentration in your blood. Dosage adjustments may be necessary.

Taking Viagra with medications that affect liver enzymes can alter its metabolism and affect its effectiveness or increase side effects. Open communication with your physician is vital for safe medication management.

This is not an exhaustive list. Consult your doctor or pharmacist for a complete list of potential drug interactions. They can help you safely manage your medications and address any concerns.
