Drug safety advice


The Department of Transport has introduced a new offence of driving with certain controlled drugs above specified limits in the blood; this is likely to come into force on 2 March 2015. The list of drugs includes some licensed medicines.


Some newly issued vials of intravenous dantrolene may contain crystals of undissolved dantrolene sodium following reconstitution. Draw up the reconstituted solution with a filter needle to prevent these crystals from being administered to patients.


Stop Press


Accidental exposure to transdermal fentanyl can occur if a patch is swallowed or transferred to another individual.


Take care to ensure that checking procedures are in place to reduce the risk of administration errors with drugs for infusion.
