Chlorpromazine Stock Problems

Some oral dosage forms of Largactil® (Chlorpromazine) have been discontinued by the manufacturer for commercial reasons. 10mg tablets, 100mg tablets and the Forte Suspension (100mg/5ml) have all been discontinued.

The largest problem appears to be affecting the 10mg tablets; there is no generic version of this product widely available. 100mg tablets and oral syrup available in 25mg/5ml and 100mg/5ml strengths remain available as generic products.

Action: Patients who are being prescribed chlorpromazine 10mg tablets should be identified and have their treatment reviewed.
