Phosphodiesterase type 5 (PDE5) inhibitor
What to do if Avanafil is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Avanafil (Avanafil) may become temporarily unavailable in some pharmacies or countries. For chronic users at 50mg, 100mg, 200mg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Avanafil
When Avanafil is in shortage, the pharmacist usually has several options: dispense an authorised generic of Avanafil, source from a different manufacturer of the same active ingredient, suggest a different formulation (e.g. liquid, dispersible) or, in extended shortages, ask the prescriber to consider an alternative Phosphodiesterase type 5 (PDE5) inhibitor agent. 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 steps
According to general pharmacy practice, the first step in a Avanafil shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Avanafil at 50mg, 100mg, 200mg. The prescriber should be informed if the pharmacist needs to substitute or change formulation. Stockpiling or buying extra outside regulated channels is not the right response.
Frequently asked questions
What do I do if my pharmacy doesn't have Avanafil? ▾
Ask the pharmacist whether an authorised generic of Avanafil is available — usually yes — or whether another pharmacy in the area has stock of Avanafil at 50mg, 100mg, 200mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Avanafil come back in stock? ▾
Most shortages are resolved within weeks to months as manufacturing or supply issues are fixed. Until then, the authorised generic of Avanafil is the standard alternative and is clinically equivalent to Avanafil at the same 50mg, 100mg, 200mg strength.
