During COVID-19 mixing drugs in syringes may be more necessary than normal. For our background page on syringe compatibility during COVID-19 go here.
Propofol is presented in a variety of forms as an aqueous isotonic oil-in-water emulsion and has an acid to base pH.
Mixing propofol with other medicines is high risk. All propofol formulations are emulsions and hence signs of physical incompatibility may be masked. In addition, pH and formulation vary between manufacturers, making extrapolating compatibility between products complex.
This page gives specific information on compatibility of propofol when combined with other medicines in a syringe. Use this information in conjunction with the detailed information on propofol in the national injectable medicines guide.
