Drug Safety Update - January 2019

The Medicines and Healthcare products Regulatory Agency (MHRA) has published Drug Safety Update for January 2019 (PDF).

This issue advises clinicians that tapentadol (Palexia®) may increase seizure risk in patients taking other medicines that lower seizure threshold. It is recommended to use with care in patients with a history of seizure disorders or epilepsy. Serotonin syndrome has also been reported when tapentadol is used in combination with serotoninergic antidepressants.

Readers are also advised that the Yellow Card App has been updated to make it easier to use and new features have been added, such as the ability to receive updates via the app.

Finally this month, the summary of letters to healthcare professionals includes notification that aciclovir eye ointment (Zovirax®) is being discontinued globally due to challenges in guaranteeing a sustainable product supply. It is expected current supplies will last until around June 2019. There is no generic direct alternative but ganciclovir has been recommended as an appropriate first-line alternative.

Action: Clinicians should be aware of this month's new guidance and implement any necessary changes to practice.
