Orlistat
About Orlistat
Orlistat is a medication prescribed to help overweight and obese individuals lose weight and keep it off. For best results, it must be taken consistently with each main meal that contains fat, alongside a reduced-calorie, low-fat diet. Incorporating regular physical activity and mindful eating habits will significantly support your weight management goals.
Because of how this medicine works, you may experience changes in your bowel habits, such as oily stools or increased gas. While these common side effects are usually manageable, you should contact your doctor if you experience severe abdominal pain or signs of liver problems.
Do not take this if you have chronic malabsorption syndrome, gallbladder issues, or if you are pregnant. It is essential to discuss your complete medical history with your doctor before starting this treatment to ensure it is safe for you.
This medication can interact with other drugs, including blood thinners, thyroid medications, and certain immune-suppressing medicines, potentially altering their effectiveness. Talk to your doctor or pharmacist if you are elderly, breastfeeding, or taking daily vitamin supplements to plan a safe dosing routine

Patients Concern
Disease/Condition Glossary
Obesity: Obesity is a common condition associated with excessive body fat, which in turn increases the risk of other health problems such as diabetes, high blood pressure, certain cancers and heart disease. Intake of more calories than you burn by exercise or daily activities results in obesity. Some common causes of obesity include insufficient sleep, growing older, pregnancy, genetics, hypothyroidism (underactive thyroid gland) or polycystic ovary syndrome (imbalance of female reproductive hormones). Proper diet and exercise are advised, along with medication to treat obesity.
FAQs
Orlistat is used to treat obesity and help in weight loss. It is to be used along with a low-calorie diet and regular physical exercise.
Orlistat contains Orlistat, which works in the small intestine and stomach and inhibits the action of enzymes that break down fat, which is absorbed by the body. Orlistat 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, Orlistat helps in weight loss.
You are not recommended to take Orlistat with ciclosporin (used for organ transplant rejections, severe rheumatoid arthritis) as it may reduce the effectiveness of ciclosporin. However, if you are supposed to take both medicines, you are advised to take ciclosporin after 3 hours of taking Orlistat. However, please consult a doctor before taking Orlistat with any other medicines.
Orlistat may cause kidney stones in patients suffering from chronic kidney disease. Therefore, if you have any kidney problems, please inform your doctor before taking Orlistat.
