Orlistat (Xenical)

Like all medicines, Orlistat can cause side effects, although not everybody gets them.

The majority of unwanted effects related to the use of Orlistat result from its local action in your digestive system. These symptoms are generally mild, occur at the beginning of treatment and are particularly experienced after meals containing high levels of fat. Normally, these symptoms disappear if you continue treatment and keep to your recommended diet.

Common side effects include:

• Fatty or oily stools
• Needing the toilet urgently
• Passing stools frequently
• Oily discharge from your rectum (you may have oily spots on your underwear)
• Flatulence (wind)
• Stomach pain or discomfort
• Headaches
  The majority of these side effects are mild and generally happen at the start of treatment. Usually, these side effects subside after continuing treatment with a healthy diet. Some of these side effects are more common if a dose is taken with a very high-fat meal.

If you experience these or any other side effects while taking this medicine seek advice from your doctor or pharmacist.

Do not take this medicine if you are allergic to any of the ingredients listed.

Please read the patient information leaflet before using this medicine.
