What to do if Caverject is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Caverject (Alprostadil) may become temporarily unavailable in some pharmacies or countries. For chronic users at 10mcg, 20mcg, 40mcg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Caverject
When Caverject is in shortage, the pharmacist usually has several options: dispense an authorised generic of Alprostadil, 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 Erectile Dysfunction (ED) agent.

Practical steps
According to general pharmacy practice, the first step in a Caverject shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Alprostadil at 10mcg, 20mcg, 40mcg. 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 Caverject? ▾
Ask the pharmacist whether an authorised generic of Alprostadil is available — usually yes — or whether another pharmacy in the area has stock of Caverject at 10mcg, 20mcg, 40mcg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Caverject 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 Alprostadil is the standard alternative and is clinically equivalent to Caverject at the same 10mcg, 20mcg, 40mcg strength.
