Which substances may interact with Xenical?
Before starting treatment, make sure your doctor knows if you are taking other medicines (including those not prescribed by your doctor). This is important as using more than one medicine at the same time can strengthen or weaken the effects of the medicines. Xenical does not affect most commonly prescribed medicines. However, it increases the effect of some lipid lowering medicines and therefore your doctor may change your dose of this medicine. Xenical reduces the absorption of supplements of some fat-soluble nutrients, particularly beta-carotene and vitamin E. You should therefore follow your doctor’s advice in taking a well balanced diet rich in fruit and vegetables.
