Discuss with your doctor all medications you are currently taking (including over-the-counter medicines and herbal products you can get without a prescription) to determine if XENICAL can be taken along with these medications. If you are taking cyclosporine, let your doctor know before taking XENICAL; cyclosporine and XENICAL should be taken at least 2 hours apart. If your cyclosporine levels are being measured, more-frequent measurements may be necessary while you�re taking XENICAL.

You Should  take a multivitamin with XENICAL because XENICAL interferes with your body’s absorption of some fat-soluble vitamins, you should take a daily multivitamin supplement that contains vitamins D, E and K and beta carotene once a day at least 2 hours before or after taking XENICAL.

If you miss a dose, you simply lose the benefit of XENICAL in blocking one-third of the fat in the food you eat at that meal. Simply resume taking XENICAL at your next meal containing fat. In clinical trials, taking additional doses of XENICAL did not improve weight loss.
