Yes, you can take Avaforce 100 mg (which contains avanafil) on an empty stomach. In fact, taking it on an empty stomach may enhance the speed of absorption, potentially allowing the medication to work faster.

Avanafil is absorbed relatively quickly, and its effectiveness is not significantly affected by food. However, taking it with a high-fat meal might slow the absorption slightly, possibly delaying its effects. To maximize its effectiveness, it’s typically recommended to take it at least 30 minutes before sexual activity, ideally on an empty stomach or after a light meal.

If you have any specific concerns or if you're taking other medications, it’s always a good idea to discuss this with your healthcare provider to ensure you're using the medication in the best way for your needs.
