Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra 800mg or any other medication. This includes nitrates, often used to treat chest pain (angina). Combining these can cause a dangerous drop in blood pressure.
Alpha-blockers, frequently prescribed for high blood pressure or enlarged prostate, may also interact with Viagra 800mg, potentially leading to dizziness or fainting. Discuss this with your physician before combining them.
Certain antifungals, such as ketoconazole and itraconazole, can increase Viagra’s concentration in your bloodstream, potentially heightening side effects. Your doctor can adjust your dosage accordingly.
Avoid grapefruit juice while taking Viagra 800mg. It can interfere with the medication’s metabolism, leading to unpredictable effects.
Never combine Viagra with other erectile dysfunction medications. This significantly increases the risk of severe side effects.
