Medicines information

At the beginning of October 2020 Essential Pharma, the manufacturer of Priadel® announced that they will continue to produce and supply Priadel® to the UK market. This was a change of heart from their decision earlier this year to discontinue Priadel®(lithium carbonate) 200mg and 400mg modified-release tablets. The decision to discontinue Priadel®was not in relation to Priadel’s safety.  

In light of this, clinicians across all healthcare settings are advised that there is no longer a need to implement system wide switching of patients from Priadel® tablets to an alternative lithium carbonate preparation until further notice.

If you are taking Priadel® brand of lithium carbonate modified release tablets continue to take it as usual, ensuring that you attend your regular blood tests. The manufacturer confirmed that there is sufficient supply of Priadel® to meet current UK demand. 

For anyone who is taking any other brand of lithium (for example, Camcolit®  or Liskonum®) there is no need to switch to Priadel®,please continue with the prescribed brand.
