What to do if Addyi is in shortage — for the United Kingdom
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Addyi (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.
the United Kingdom context
Drug shortages in the United Kingdom are tracked by MHRA (Medicines and Healthcare products Regulatory Agency) when significant. For Addyi, shortage of one strength or one manufacturer rarely means total unavailability of Flibanserin — authorised generics or alternative manufacturers usually fill the gap, with the pharmacist coordinating substitution and the prescriber confirming any formulation change at 100mg.

How shortages work for Addyi
When Addyi 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 Women's Sexual Health agent. Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory).
Practical steps
According to general pharmacy practice, the first step in a Addyi 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 Addyi? ▾
Ask the pharmacist whether an authorised generic of Flibanserin is available — usually yes — or whether another pharmacy in the area has stock of Addyi at 100mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Addyi 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 Addyi at the same 100mg strength.
