Important information about Xenical

How should I take Xenical?

Take Xenical exactly as directed on the label, or as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Xenical is only part of a complete program of treatment that also includes diet, exercise, and weight control. Your daily intake of fat, protein, and carbohydrates should be evenly divided over all of your daily meals. Follow your diet, medication, and exercise routines very closely.

Take Xenical during or within 1 hour after a meal that contains some fat (no more than 30% of the calories for that meal). Xenical is usually taken 3 times daily.

The fat content of your daily diet should not be greater than 30% of your total daily caloric intake. For example, if you eat 1200 calories per day, no more than 360 of those calories should be in the form of fat.

Your doctor may recommend you take vitamin and mineral supplements while you are taking Xenical. This medication can make it harder for your body to absorb fat-soluble vitamins, such as vitamins A, D, E, and K. 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 Xenical.

Store Xenical at room temperature away from moisture and heat. Keep the bottle tightly closed.

Keep track of how many capsules have been used from each new bottle. Xenical is a drug that may be misused as a weight-loss aid, and you should be aware if any person in the household is using this medicine improperly or without a prescription.

What happens if I miss a dose?

Take the missed dose as soon as you remember, but no more than 1 hour after eating a meal. If it has been more than an hour since your last meal, skip the missed dose and take the medicine at your next regularly scheduled time. Do not take extra medicine to make up the missed dose. If you miss a meal, or if you have a meal without fat, you can skip your dose of Xenical for that meal also.
