Avanafil, like other PDE5 inhibitors, can cause side effects. Commonly reported side effects include headache, flushing, nasal congestion, and back pain. These are usually mild and temporary. Less frequent, but still possible, are visual disturbances (such as blurred vision or changes in color perception), dizziness, and nausea.
It’s crucial to understand that the severity of side effects can vary from person to person. If you experience any persistent or severe side effects, immediately contact your doctor.
Avanafil can interact with certain medications. This is especially true for nitrates (used to treat angina) and alpha-blockers (used to treat high blood pressure and enlarged prostate). Combining Avanafil with these medications can lead to dangerously low blood pressure. Always inform your doctor of all medications you are currently taking, including over-the-counter drugs and supplements.
Specific interactions warrant extra caution. The following table summarizes some key drug interactions:
| Nitrates | Severe hypotension | Avoid concurrent use. |
| Alpha-blockers | Hypotension | Monitor blood pressure closely. |
| Ritonavir or Saquinavir (HIV protease inhibitors) | Increased Avanafil levels | Doctor supervision is needed. Dose adjustment may be necessary. |
| Ketoconazole or Itraconazole (antifungals) | Increased Avanafil levels | Doctor supervision is needed. Dose adjustment may be necessary. |
This information is not exhaustive. Always consult your doctor or pharmacist before taking Avanafil, particularly if you have pre-existing health conditions or are taking other medications. They can provide personalized advice and assess any potential risks.
