A class 4 alert has been issued for Priadel Liquid by the MHRA.

Priadel Liquid (Lithium Citrate 520mg/5ml equivalent to Lithium Carbonate 204mg/5ml) appears cloudy rather than clear. A detailed investigation carried out by Sanofi, the manufacturer, “has shown that the cloudiness is not due to microbial contamination. The root cause has been attributed to a change of source for one of the excipients, Xanthan gum. The availability of Lithium in the product is not affected by this change and dosing should not be affected.”

The advice therefore is that although it may be cloudy, it is clearly OK to use.
