DPP-4 inhibitor
What to do if Sitagliptin is in shortage
Drug shortages happen periodically — manufacturing issues, supply chain disruptions, regulatory holds — and Sitagliptin (Sitagliptin) may become temporarily unavailable in some pharmacies or countries. For chronic users at 25mg, 50mg, 100mg, knowing how to handle a shortage prevents unnecessary treatment interruption.
How shortages work for Sitagliptin
When Sitagliptin is in shortage, the pharmacist usually has several options: dispense an authorised generic of Sitagliptin, 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 DPP-4 inhibitor agent. Sitagliptin reversibly inhibits DPP-4, the serine protease responsible for rapid degradation of glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).
Practical steps
According to general pharmacy practice, the first step in a Sitagliptin shortage is to ask the pharmacist about authorised generic availability — most shortages affect a single brand or strength, not the entire supply of Sitagliptin at 25mg, 50mg, 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 Sitagliptin? ▾
Ask the pharmacist whether an authorised generic of Sitagliptin is available — usually yes — or whether another pharmacy in the area has stock of Sitagliptin at 25mg, 50mg, 100mg. The pharmacist can also contact the prescriber if a formulation switch is needed.
Will Sitagliptin 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 Sitagliptin is the standard alternative and is clinically equivalent to Sitagliptin at the same 25mg, 50mg, 100mg strength.
