The active substance is orlistat. Each capsule contains 120 mg of orlistat. The other ingredients are microcrystalline cellulose (E460), sodium starch glycolate (type A), povidone (E1201), sodium laurilsulfate and talc. The capsule shell consists of gelatine, indigo carmine (E132), titanium dioxide (E171) and edible printing ink.

Xenical (orlistat) 120 mg may cause side effects in some people. These side effects are usually mild and temporary, especially at the start of treatment.

Common side effects are mainly related to the way Xenical works in the digestive system and may include oily spotting from the rectum, an urgent need to open the bowels, oily or fatty stools, loose or watery stools, increased flatulence sometimes accompanied by oily discharge, more frequent bowel movements, and mild abdominal discomfort or stomach pain.

In rare cases, more serious side effects can occur, such as severe abdominal pain, severe diarrhoea, or signs of liver problems. If you experience symptoms such as persistent or severe abdominal pain, dark urine, yellowing of the skin or eyes (jaundice), or any other unusual or severe symptoms, stop taking Xenical and seek medical advice immediately.

This is not a complete list of possible side effects. If you experience any side effects not listed here, or if side effects persist or cause concern, speak to your healthcare professional.

Before using Xenical (orlistat) 120 mg, it is important to take the following warnings and precautions into account. Inform your healthcare professional if you have any allergies, particularly if you are allergic to orlistat or any of the other ingredients in this medicine. Xenical should not be used during pregnancy or while breastfeeding unless specifically advised by a healthcare professional.

Discuss your medical history with your healthcare professional, especially if you have a history of kidney stones, pancreatitis, gallbladder disease, liver problems, or if you are taking other medicines. Xenical can reduce the absorption of fat-soluble vitamins (A, D, E, and K), so a daily multivitamin supplement containing these vitamins is usually recommended. This supplement should be taken at a different time of day, according to the advice of your healthcare professional, to help ensure adequate nutrition.

Xenical is most effective when used alongside a reduced-calorie, balanced diet and regular physical activity. In some cases, nutritional guidance may be recommended to support safe and effective weight loss. In rare instances, Xenical has been associated with liver problems. Contact your healthcare professional immediately if you experience symptoms such as dark urine, yellowing of the skin or eyes (jaundice), or persistent abdominal pain.

The safety and effectiveness of Xenical have not been established in children under 12 years of age. Use in older adults should be assessed on an individual basis by a healthcare professional. If you accidentally take more Xenical capsules than prescribed, seek medical advice promptly.
