Potential Side Effects and Interactions

Seek immediate medical attention if you experience chest pain, irregular heartbeat, or prolonged erection (lasting more than four hours).

Common side effects include headache, flushing, nasal congestion, and upset stomach. These usually subside on their own, but if they persist or worsen, consult your doctor.

Viagra can interact negatively with certain medications. Avoid using it concurrently with nitrates (used to treat chest pain), alpha-blockers (used to treat high blood pressure), or some antifungal medications. This combination can dangerously lower blood pressure.

Grapefruit juice can also interact with Viagra, potentially increasing its concentration in your bloodstream. Limit or avoid grapefruit juice while taking this medication.

Always inform your doctor about all medications and supplements you’re taking, including herbal remedies. This allows your doctor to assess potential interactions and recommend the safest approach.
