Potential Interactions with Other Medications

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

Alpha-blockers, used to treat high blood pressure and enlarged prostate, may also interact with Viagra, potentially leading to low blood pressure. Your doctor might adjust your dosage or recommend an alternative.

Certain antifungal medications, such as ketoconazole and itraconazole, can increase Viagra’s concentration in your blood, potentially increasing side effects. Your doctor may need to lower your Viagra dosage.

Some HIV protease inhibitors can also interact with Viagra, potentially raising Viagra levels in the bloodstream. Careful monitoring and potential dosage adjustments are necessary.

Avoid grapefruit juice while taking Viagra. Grapefruit can interfere with the breakdown of Viagra, leading to higher blood levels and increased side effects.

This list isn’t exhaustive; many other medications could potentially interact. Open communication with your healthcare provider is critical for safe medication use.
