Cetilistat
About Cetilistat
Cetilistat is a prescription medicine designed to aid in weight loss and obesity management. Its primary medical purpose is to help individuals with a high body mass index (BMI) lose weight and maintain that weight loss over time. Cetilistat is generally prescribed for adults with a body mass index (BMI) of 30 kg/m² or higher, or 27 kg/m² or higher if they have obesity-related health conditions, as determined by their doctor.
This medicine is typically taken during or shortly after meals that contain fat. For the best results, you must take it consistently as directed by your healthcare provider, alongside a reduced-calorie, low-fat diet and regular physical activity.
Common side effects are mostly digestive, such as oily stools or increased gas, which occur as the body expels unabsorbed fat. You should consult your doctor immediately if you experience severe abdominal pain, persistent nausea, or yellowing of your eyes or skin.
Talk to your doctor before starting this medicine if you have a history of kidney stones or other metabolic issues. Do not take this if you suffer from chronic malabsorption syndrome or cholestasis, or if you are pregnant or breastfeeding.
This medicine can interact with blood thinners, thyroid therapies, and certain immune-suppressing drugs, as well as lower the absorption of vital fat-soluble vitamins. Always discuss these interactions with your healthcare provider, especially if you belong to specific user groups like the elderly.

Cetilistat contains Cetilistat that works in the small intestine and stomach and inhibits the action of enzymes that breakdown fat which is absorbed by the body. Cetilistat decreases the absorption of fat from the food you eat. Thus, fat passes through the gut and is excreted in the faeces, which makes the body unable to use fat as a source of energy or convert it into fat tissue. Thereby, Cetilistat helps in weight loss.
Cetilistat should be used with caution in diabetic patients as it may increase the risk of low blood sugar levels. Therefore, inform your doctor if you have diabetes before taking Cetilistat so that the dose of antidiabetic medicine may be adjusted accordingly.
You are not advised not to take cyclosporine (used for organ transplant rejections, severe rheumatoid arthritis) with Cetilistat as it may reduce the effectiveness of cyclosporine. However, if you are supposed to take both medicines, you are advised to take cyclosporine after 3 hours of taking Cetilistat. However, please consult a doctor before taking Cetilistat with any other medicines.
You are advised to avoid high fat meals that includes butter, meat, dark chocolate, olive oil, nuts and seeds (brazil nuts) with Cetilistat as it may increase the risk of adverse effects on stomach or intestines.
You are recommended to use Cetilistat for as long as your doctor has prescribed it. However, avoid taking Cetilistat for more than 6 months. If you do not notice weight loss after taking Cetilistat for 12 weeks, please consult a doctor.
You are advised to take multivitamin containing fat-soluble vitamins such as A, D, E and K at bedtime or at least 2 hours after taking Cetilistat. Generally, Cetilistat may reduce the absorption of certain vitamins in the body. Therefore, your doctor may advise you to take multivitamins.
No, do not take this medicine if you are pregnant, planning to become pregnant, or breastfeeding. Weight loss is not recommended during pregnancy, and the effects on nursing infants are not fully known. Talk to your doctor for safe alternatives.
If you eat a meal that contains no fat, or if you skip a meal, you should skip your dose of Cetilistat. The medicine only works when there is dietary fat to block. Talk to your doctor or pharmacist if you are unsure about your dietary plan.
Oily stools occur because the medicine prevents a portion of the fat you eat from being digested. This undigested fat passes directly through your system. You can minimise this effect by limiting your daily fat intake to about 30% of your total calories. Talk to your doctor if these symptoms become severe.
Alcohol does not directly interact with the medicine, but alcoholic beverages are often high in calories and can slow down your weight loss progress. Talk to your doctor about your alcohol consumption while managing your weight.
You should not combine this medicine with other weight loss products unless specifically instructed to do so by your doctor. Combining therapies can increase the risk of side effects. Talk to your doctor before starting any new treatments.
