💊 Adverse Effects, Treatment, and Precautions

In some countries hepatic and haematological monitoring is recommended in patients receiving glimepiride; in the UK the BNF considers the practical value of such monitoring unproven.


Glimepiride, given in unchanged doses but with the time of the single daily dose switched from morning to just before breaking fast after sunset, was used in Muslim patients during Ramadan without causing an increased incidence of hypoglycaemic episodes.1 For further advice on the management of diabetes mellitus in fasting Muslim patients during Ramadan see under Precautions of Insulin.

💊 Pharmacokinetics

Glimepiride is completely absorbed from the gastrointestinal tract. Peak plasma concentrations occur in 2 to 3 hours, and it is highly protein bound. The drug is extensively metabolised to two main metabolites, a hydroxy derivative and a carboxy derivative. The half-life after multiple doses is about 9 hours. About 60% of a dose is eliminated in the urine and 40% in the faeces.

💊 Uses and Administration

Glimepiride is a sulfonylurea antidiabetic. It is given orally for the treatment of type 2 diabetes mellitus. Initial doses of 1 to 2 mg daily may be increased if necessary to 4 mg daily for maintenance. The maximum recommended dose is 6 mg in the UK and 8 mg in the USA.
