Phosphodiesterase type 5 (PDE5) inhibitor
Avanafil with diabetes medications (metformin, insulin)
Diabetes is one of the most common chronic conditions worldwide, so many adults taking Avanafil (Avanafil) are also on metformin, a sulfonylurea, insulin, a GLP-1 agonist or an SGLT2 inhibitor. The combination at 50mg, 100mg, 200mg is mostly straightforward but a few specific interactions deserve attention to prevent unexpected hypoglycaemia or loss of glucose control.
Diabetes-medication interactions with Avanafil
Avanafil typically does not directly alter blood glucose, but co-administered medications may. Some agents in Phosphodiesterase type 5 (PDE5) inhibitor indirectly affect insulin sensitivity, appetite or weight, which shifts antidiabetic effect. Sulfonylureas and insulin are the antidiabetics most prone to amplified hypoglycaemia when co-prescribed with interacting medications. Avanafil selectively inhibits phosphodiesterase type 5 (PDE5) in the corpus cavernosum, increasing cGMP and enhancing nitric-oxide-mediated vasodilation in response to sexual stimulation.
Practical guidance
According to the prescribing information for Avanafil, people with diabetes can usually start Avanafil at the standard 50mg, 100mg, 200mg dose with closer self-monitoring of glucose for the first weeks. Insulin doses sometimes need adjustment if Avanafil affects appetite, weight or glucose handling. Diabetes-related complications (renal, cardiovascular, autonomic) may shift the risk-benefit balance.

Metformin has few interactions with Avanafil; the practical considerations are similar gastrointestinal side effects (which can be amplified) and renal function monitoring. The pharmacist confirms based on the full medication list.
Will Avanafil cause low blood sugar with insulin? ▾
Direct hypoglycaemic effects of Avanafil are typically minor or absent. However, indirect effects from changes in appetite, sleep or activity can shift insulin requirements. Closer self-monitoring during the first weeks at 50mg, 100mg, 200mg is the safe practice; insulin dose adjustments are made by the prescriber based on observed patterns.
