Take orlistat during or within 1 hour after a meal that contains some fat (no more than 30% of the calories for that meal). Orlistat is usually taken 3 times daily. If you skip a meal or you eat a meal that does not contain any fat, skip your orlistat dose for that meal.

The fat content of your daily diet should not be greater than 30% of your total daily caloric intake. Avoid a diet that is high in fat. High-fat meals taken in combination with orlistat can increase your risk of unpleasant side effects on your stomach or intestines.

Your doctor may recommend you take vitamin and mineral supplements while you are taking orlistat.

Follow your doctor's instructions about the type of multi-vitamin or mineral supplement to use. Take the supplement at least 2 hours before or after you take orlistat.
