The presentations affected by the shortage are:
- Insuman Basal cartridge
- Insuman Comb 25 cartridge
- Insuman Basal Solostar pre-filled pen
- Insuman Comb 25 Solostar pre-filled pen.
In a letter to healthcare professionals, Sanofi recommends that patients who are unable to obtain these products be switched to an alternative human insulin preparation.
Patients treated with Insuman Comb 25 can be switched to Humulin M3. This patient group may require dose adjustment as the ratio of rapid/basal insulin in Humulin M3 is slightly different to that in Insuman Comb 25 (30% rapid insulin instead of 25%).
Close monitoring of blood glucose levels and training on how to use the new delivery device is recommended when switching.
Prescribers can call the Insuman Emergency Line on 0800 281973 to discuss individual cases where switching may not be appropriate.
Supply is expected to return to normal in July 2016.
