Interactions with Other Medications and Substances

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

Alpha-blockers, commonly used to treat high blood pressure or prostate problems, can also interact with Viagra, potentially leading to dizziness or fainting. Discuss this interaction thoroughly with your physician before combining these medications.

Certain antifungal medications, such as ketoconazole and itraconazole, can increase Viagra’s levels in your blood, potentially causing side effects. Your doctor may adjust your Viagra dosage if you’re taking these drugs.

Grapefruit juice can affect how your body processes Viagra. Avoid grapefruit juice while taking this medication to prevent unpredictable reactions. The same caution applies to other grapefruit-containing products.

Taking Viagra with alcohol can increase the risk of side effects such as dizziness and headaches. Moderate alcohol consumption should be discussed with your doctor, considering your personal health profile.
