Sildenafil, while generally safe, can cause side effects. Common ones include headaches, flushing, nasal congestion, and indigestion. These usually are mild and temporary. Less common, but still possible, are visual disturbances like blurred vision or changes in color perception. Rarely, more serious side effects like prolonged erection (priapism) or sudden vision or hearing loss occur. Seek immediate medical attention if you experience any of these serious side effects.
Sildenafil interacts with certain medications. Nitrates, commonly used to treat chest pain, are a significant concern; combining them with sildenafil can dangerously lower blood pressure. Alpha-blockers, sometimes prescribed for high blood pressure or prostate problems, can also interact, potentially leading to dizziness or fainting. Other medications, including some antifungals and antibiotics, may also interact. Always inform your doctor about all medications, supplements, and herbal remedies you’re taking before starting sildenafil.
Alcohol consumption can exacerbate sildenafil’s side effects. Moderate alcohol intake is generally fine, but excessive drinking should be avoided. Grapefruit juice can also interact, increasing sildenafil levels in the body. Limit or avoid grapefruit juice while taking sildenafil.
Pre-existing conditions like heart disease, stroke, low blood pressure, or severe liver or kidney problems can influence sildenafil’s safety and effectiveness. Consult your doctor to discuss any health concerns before using this medication.
