Prostaglandin E1 (PGE1)
What to do if Alprostadil is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Alprostadil (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 Alprostadil
When Alprostadil 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 Prostaglandin E1 (PGE1) agent. Alprostadil binds prostaglandin E receptors on smooth muscle of the corpus cavernosum, triggering cAMP-mediated relaxation of cavernosal smooth muscle independent of the nitric oxide pathway used by P…
Practical steps
According to general pharmacy practice, the first step in a Alprostadil 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 Alprostadil? ▾
Ask the pharmacist whether an authorised generic of Alprostadil is available — usually yes — or whether another pharmacy in the area has stock of Alprostadil at 10mcg, 20mcg, 40mcg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Alprostadil 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 Alprostadil at the same 10mcg, 20mcg, 40mcg strength.
