What are the Indications for Xenical?
Xenical is approved for the treatment of obesity management, including weight loss and weight maintenance, especially if you have other risk factors, like high blood pressure, diabetes, or hyperlipidemia.
How is Xenical used?
Spiriva should be stored in its original packaging at 77°F (25°C) with excursions permitted between 59-86°F (15-30°C).
Keep the bottle tightly closed and out of reach of children.
Take medication as directed by your doctor, by mouth with liquid during a meal that contains fat, or within 1 hour after a meal. If you miss a meal or your meal does not contain fat, skip that dose of the medication.
Do not change your dosage and take more than what is prescribed, as it will not improve your condition faster, and increase your risk of side effects. If you took more than prescribed, contact your doctor immediately or seek emergency medical care.
Xenical is available in a 120 mg capsule form and should be taken 3 times a day with a meal that contains fat, or within 1 hour of finishing the meal.
It’s important to understand that although Xenical is FDA-approved, it comes with side effects that may or may not affect you.
To reduce the chance of unpleasant side effects, only 30% of the calories in your diet should come from fat. Your daily intake of fat, protein, and carbohydrates should be spread evenly over 3 main meals.
Before starting, you should discuss possible side effects with your doctor or pharmacist.

Warnings & Precautions
Before using Xenical, tell your doctor or pharmacist:
- If you are allergic to it or any ingredients
- If you are pregnant or plan to become pregnant
- If you are breastfeeding or plan to breastfeed
- If you don’t see any weight loss within 2 weeks of starting Xenical, or picking up weight
- If you suffer from chronic malabsorption syndrome or cholestasis (reduced bile flow from the liver)
Xenical can interfere with the absorption of nutrients and can cause diarrhea, bloating, abdominal pain, and fatigue.
Xenical can cause a reduced flow of bile from the liver and can cause damage to the liver cells and other health problems.
Pregnant or Planning to Become Pregnant
Do not use Xenical if you are pregnant as weight loss is not recommended during pregnancy and may harm an unborn baby.
Breastfeeding or Planning to Breastfeed
Xenical may pass into breast milk in small amounts. Speak to your doctor about whether you should continue breastfeeding.
