Consult your doctor before using generic Avanafil, especially if you have heart problems, low blood pressure, or bleeding disorders. They can assess your suitability and discuss potential risks.
Common Side Effects
Headache is the most frequent side effect. Drink plenty of water and consider over-the-counter pain relievers like ibuprofen or acetaminophen. If headaches are severe or persistent, contact your doctor.
Nasal congestion can also occur. Try saline nasal sprays or a humidifier to alleviate symptoms. If congestion is severe or lasts longer than a few days, seek medical attention.
Flushing (redness of the face, neck, and chest) is another common side effect. This usually subsides on its own. Staying hydrated can help.
Back pain and muscle aches are possible. Gentle exercise and rest can help. If pain is severe or persistent, consult your physician.
Less Common, but Serious Side Effects
Seek immediate medical attention if you experience: sudden vision loss, prolonged erection (priapism), hearing loss, chest pain, irregular heartbeat, or a sudden drop in blood pressure.
