MHRA Drug Safety Update
When prescribing any selective serotonin reuptake inhibitor, the MHRA reminds prescribers to enquire about cocaine use when considering drug-drug interactions and to avoid concurrent use of multiple serotonergic drugs.
The possibility of illicit drug use and interactions should always be considered when prescribing any medicines that have the potential to interact adversely.
