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, can also interact with Viagra, potentially leading to low blood pressure. Your doctor might adjust your dosage or recommend alternatives.
Certain antifungals, such as ketoconazole and itraconazole, can increase Viagra’s concentration in your blood, potentially leading to side effects. Your doctor may need to lower your Viagra dosage.
Some HIV protease inhibitors can also interact with Viagra, possibly increasing its levels in the blood. Close monitoring and potential dosage adjustments are necessary.
Avoid grapefruit juice while taking Viagra. Grapefruit can affect how your body processes the medication, potentially leading to higher levels in your blood and increased risk of side effects.
