Second-generation H1 antihistamine
What to do if Loratadine is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Loratadine (Loratadine) may become temporarily unavailable in some pharmacies or countries. For chronic users at 5mg, 10mg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Loratadine
When Loratadine is in shortage, the pharmacist usually has several options: dispense an authorised generic of Loratadine, 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 Second-generation H1 antihistamine agent. Loratadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released during allergic reactions.
Practical steps
According to general pharmacy practice, the first step in a Loratadine shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Loratadine at 5mg, 10mg. 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 Loratadine? ▾
Ask the pharmacist whether an authorised generic of Loratadine is available — usually yes — or whether another pharmacy in the area has stock of Loratadine at 5mg, 10mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Loratadine 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 Loratadine is the standard alternative and is clinically equivalent to Loratadine at the same 5mg, 10mg strength.
