Grapefruit juice interacts with Viagra (sildenafil) by inhibiting certain enzymes in your liver that metabolize the drug. This leads to higher and potentially dangerous levels of sildenafil in your bloodstream.
Cardiovascular Effects
- Increased risk of low blood pressure (hypotension). Monitor your blood pressure regularly, especially after taking Viagra, and report any significant drops to your doctor. Potential for irregular heartbeat (arrhythmia). Pay attention to your heart rate and rhythm; consult your doctor if you notice any abnormalities. Chest pain (angina). This is a serious symptom and requires immediate medical attention.
Other Potential Side Effects
Headache: This is a common side effect of Viagra, and grapefruit juice can exacerbate it. Facial flushing: You may experience redness in your face and neck. Indigestion: Some individuals experience heartburn or upset stomach. Visual disturbances: Blurred vision, changes in color perception, or light sensitivity can occur. Prolonged erection (priapism): This is a rare but serious complication requiring immediate medical intervention. Seek medical help immediately if an erection lasts longer than four hours.
Important Considerations
