Complete Guide: Using Orlistat 120mg Safely & Effectively
How Orlistat 120mg Works for Weight Management
Orlistat 120mg works by blocking approximately one third of the dietary fat you consume from being absorbed in your digestive system. This prescription weight loss medication inhibits lipase enzymes in the gut, allowing unabsorbed fat to pass naturally through your body. Unlike appetite suppressants, orlistat acts locally in the digestive system and may help support weight management when used alongside a reduced-calorie, lower-fat diet and increased physical activity.
Proper Dosage Instructions for Xenical Orlistat 120mg
Take one orlistat 120mg capsule three times daily with each main meal containing fat. Each capsule should be taken immediately before, during, or up to one hour after eating. If you skip a meal or eat a meal with no fat, you can skip that dose. Never exceed three capsules per day. At EverydayMeds, our 84-capsule pack provides a 4-week supply at £29.69 with code EDM10, while our 168-capsule pack offers 8 weeks' treatment for £57.59.
Orlistat vs Xenical: Choosing Your Treatment Option
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and provide equivalent clinical effects. Generic orlistat offers excellent value at £29.69 per 4-week supply, while Xenical 120mg costs £38.69 for the same period with EDM10 discount. Some patients prefer the branded option, whilst others choose generic orlistat for cost-effectiveness. Our UK-licensed prescribers can help determine which option suits your weight management goals following clinical assessment.
Diet Guidelines While Using Orlistat
Success with orlistat depends on maintaining a reduced-calorie, lower-fat diet with approximately 30% of daily calories from fat. Spread your fat intake evenly across three main meals (roughly 15g fat per meal) to minimise gastrointestinal side effects. High-fat meals significantly increase the likelihood of side effects including oily stools and urgent bowel movements. Consider taking a daily multivitamin at bedtime, as orlistat may reduce absorption of fat-soluble vitamins A, D, E, and K.
Getting Your Prescription Through EverydayMeds
Our streamlined online process makes accessing prescription weight loss treatment convenient. Complete our confidential health questionnaire, which a UK-licensed prescriber reviews to assess your suitability for orlistat treatment. If approved, we dispense your medication from our GPhC-registered pharmacy in Leicester with next day delivery available. Our 12-week supply (252 capsules) of generic orlistat costs just £86.39 with EDM10, providing excellent value for extended weight management support.
Managing Side Effects and Treatment Success
Most orlistat side effects are gastrointestinal and directly related to dietary fat intake. Common effects include oily or fatty stools, increased bowel movement frequency, and oily spotting. These side effects typically reduce as you adapt to eating lower-fat meals and are actually signs that the medication is working. If side effects are severe or persistent, consult your healthcare professional. Remember that orlistat works best as part of a comprehensive weight management programme including dietary changes and increased physical activity.
