Avanafil, like other PDE5 inhibitors, may cause side effects. The most common include headache, flushing, nasal congestion, and back pain. These usually are mild and temporary.
Headache is frequently reported; staying hydrated can help. Facial flushing is another common occurrence; avoid excessive alcohol consumption.
Nasal congestion can be managed with over-the-counter decongestants, but consult your doctor before using them, especially if you have other health concerns. Back pain, if bothersome, might respond to over-the-counter pain relievers, but check with your physician first.
Less frequent, but still possible, side effects include dizziness, visual disturbances (blurred vision, changes in color perception), and muscle aches. Seek medical attention immediately if you experience a sudden decrease or loss of vision, or if you experience an erection lasting longer than four hours (priapism).
Precautions are vital. Avanafil is not suitable for everyone. Do not use Avanafil if you have heart problems, low blood pressure, or a history of stroke. Individuals using nitrates for chest pain should also avoid Avanafil, as the combination can cause a dangerous drop in blood pressure.
Inform your doctor about all medications you’re taking, including prescription and over-the-counter drugs, and herbal supplements. Grapefruit juice can interact negatively with Avanafil; avoid consumption. Finally, discuss any pre-existing conditions with your doctor before starting Avanafil.
