Potential Side Effects and Precautions

Avanafil can cause headaches, flushing, nasal congestion, and back pain. These side effects are generally mild and temporary. If you experience a prolonged or severe headache, seek immediate medical attention.

Vision Changes

Some users report changes in vision, including blurred vision or temporary blue-tinted vision. This usually resolves quickly. Stop taking avanafil and contact your doctor if vision problems persist or worsen.

Heart Conditions

Avanafil may lower blood pressure. Consult your physician before using avanafil if you have heart disease, high or low blood pressure, or have recently had a heart attack or stroke. Avoid strenuous activity shortly after taking avanafil.

Inform your doctor about all medications you are currently taking, including prescription and over-the-counter drugs, as interactions are possible. Do not take avanafil with nitrates, as this combination can cause a dangerous drop in blood pressure.

Other Precautions

Avoid alcohol consumption while using avanafil, as it can increase the risk of side effects. If you experience an erection lasting longer than four hours (priapism), seek immediate medical assistance. This is a serious condition requiring prompt treatment.
