Supply Disruption Alert – Lithium carbonate (Priadel®) 200mg and 400mg modified release tablets

August 21, 2020

Update as of 8th October 2020

Essential Pharma has informed the Department of Health and Social Care (DHSC) of its decision to reverse the discontinuation of Priadel 200mg and 400mg tablets from the UK market with immediate effect, whilst facilitating pricing discussions. As such the discontinuation notice issued to DHSC earlier this year has been withdrawn.

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.

Essential Pharma has confirmed supplies of Priadel 200mg and 400mg tablets are sufficient to meet current UK demand and is working to ensure further stocks are available to maintain supply after April 2021.

The Department of Health and Social Care (DHSC) have issued a supply disruption alert for Lithium carbonate (Priadel®) 200mg and 400mg modified release tablets

  • Priadel®(lithium carbonate) 200mg and 400mg modified-release tablets are being discontinued in the UK and remaining supplies of both strengths are expected to be exhausted by April 2021.
  • Lithium (Priadel®, Camcolit® and Liskonum® brands) is a first line treatment for patients with bipolar disorder. It is also licensed for the treatment and prophylaxis of recurrent depression, and aggressive or self-harming behaviour, and used off-license in the treatment of cluster headaches.
  • Clinical guidance advises that patients must be maintained on the same brand of lithium to ensure that a consistent serum lithium level is maintained. The switching of brands necessitated by this SDA will require individualised determination of dose, close monitoring of serum lithium levels and vigilance for relapse and tolerability in all cases.
  • Other brands of lithium carbonate tablets remain available including Liskonum® 450mg modified release tablets, Camcolit® 400mg modified-release tablets and lithium carbonate Essential Pharma 250mg tablets.

Priadel 520mg/5ml liquid is not being discontinued but please note this contains lithium citrate, not lithium carbonate, information on switching to liquid preparations is not included within this alert; if prescribers deem a switch to a liquid formulation appropriate, relevant guidance should be consulted to ensure safe switching.
