Droperidol, the active ingredient in Xomolix, can increase the effects of sedatives such as barbiturates, benzodiazepines and morphine based products. It can also increase the effects of medication used to lower high blood pressure (antihypertensives) and a number of other medicines e.g. certain antifungals, antivirals, and antibiotics. Some medicines may also increase the effects of droperidol e.g. cimetidine (for gastric ulcers), ticlopidine (to prevent blood-clotting) and mibefradil (for angina). If you are in any doubt please talk to your doctor or nurse.
