Multifunctional serotonin agonist/antagonist (HSDD)
What to do if Flibanserin is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Flibanserin (Flibanserin) may become temporarily unavailable in some pharmacies or countries. For chronic users at 100mg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Flibanserin
When Flibanserin is in shortage, the pharmacist usually has several options: dispense an authorised generic of Flibanserin, 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 Multifunctional serotonin agonist/antagonist (HSDD) agent. Flibanserin acts as a serotonin 5-HT1A receptor agonist and 5-HT2A receptor antagonist, with additional effects on dopamine and norepinephrine signalling.
Practical steps
According to general pharmacy practice, the first step in a Flibanserin shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Flibanserin at 100mg. 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 Flibanserin? ▾
Ask the pharmacist whether an authorised generic of Flibanserin is available — usually yes — or whether another pharmacy in the area has stock of Flibanserin at 100mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Flibanserin 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 Flibanserin is the standard alternative and is clinically equivalent to Flibanserin at the same 100mg strength.
