Always consult your doctor before using avanafil. Some men experience mild side effects, such as headaches, flushing, nasal congestion, and back pain. These usually subside quickly.
More serious, though rare, side effects include sudden vision loss, hearing loss, or prolonged erection (priapism). Seek immediate medical attention if you experience any of these.
Medication Interactions
Avanafil can interact with certain medications, including nitrates used to treat chest pain. Combining them can cause a dangerous drop in blood pressure. Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements.
Heart Conditions
Men with heart problems should exercise caution. Avanafil can strain the heart, so discuss its use with your cardiologist before starting treatment. This is especially true if you have a history of heart attack, stroke, or irregular heartbeat.
Pre-existing Conditions
| High blood pressure | Monitor blood pressure regularly; avanafil might affect it. |
| Liver or kidney disease | Dosage adjustments may be necessary; discuss with your doctor. |
| Sickle cell anemia | Increased risk of priapism; avoid use. |
Dosage
Follow your doctor’s prescribed dosage carefully. Do not exceed the recommended amount. Your doctor will help you determine the appropriate dose based on your individual needs and health status.
Alcohol Consumption
Excessive alcohol consumption can worsen side effects. Limit alcohol intake while using avanafil.
