Viagra Interactions with Other Medications and Substances

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 prescribed for chest pain. Combining these can cause a dangerous drop in blood pressure.

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

Certain antifungal medications, like ketoconazole and itraconazole, can increase Viagra’s concentration in your blood, potentially increasing side effects. Close monitoring by your physician is recommended.

Grapefruit juice can interfere with Viagra’s metabolism, leading to elevated blood levels and a heightened risk of side effects. Avoid grapefruit juice while using Viagra.

High blood pressure medication can interact with Viagra. Closely monitor your blood pressure if using both. Your doctor will provide guidance on safe usage and dosage.

Never combine Viagra with recreational drugs, especially those that affect your blood pressure or heart. This significantly increases your risk of serious complications.
