Orlistat - How much fat do I take each meal?

You need to have no more than 45gms of fat per day. If you go over you may have some oily problems.

How should I take orlistat?
Use orlistat exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

Never share orlistat with another person, especially someone with a history of eating disorders.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Orlistat is usually taken 3 times per day with each main meal that contains some fat (no more than 30% of the calories for that meal). You may take the medicine either with your meal or up to 1 hour after eating.

If you skip a meal or you eat a meal that does not contain any fat, skip your dose for that meal.

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.

Read the label of all food items you consume, paying special attention to the number of servings per container. Your doctor, nutrition counselor, or dietitian can help you develop a healthy eating plan.

Orlistat is only part of a complete program of treatment that also includes diet and exercise. 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.

Orlistat can make it harder for your body to absorb certain vitamins, and you may need to take a vitamin and mineral supplement while you are taking this medicine. Follow your doctor's instructions about the type of supplement to use. Take the supplement at bedtime, or at least 2 hours before or after you take orlistat.

Store at room temperature away from moisture, heat, and light. Keep the bottle tightly closed. Throw away any unused orlistat after the expiration date on the medicine label has passed.
