Orlistat vs Ozempic: Key Differences for UK Patients
Both orlistat and Ozempic (semaglutide) are prescription-only weight management medications available through private prescription in the UK, but they work very differently. Orlistat 120mg works locally in your gut by blocking approximately one third of dietary fat absorption, whilst Ozempic is an injectable GLP-1 receptor agonist that may help reduce appetite and slow gastric emptying. Understanding these differences helps you make an informed choice during your private consultation.
How Orlistat Works - Fat Absorption Blocker
Orlistat inhibits lipase enzymes in your digestive system, preventing approximately one third of the fat you eat from being absorbed. This unabsorbed fat passes naturally through your body. Available as generic orlistat 120mg from £15.20 for 2 weeks or branded Xenical 120mg from £19.35 with EDM10. Unlike Ozempic, orlistat is taken orally three times daily with meals containing fat and doesn't affect blood sugar directly.
How Ozempic Works - GLP-1 Receptor Agonist
Ozempic contains semaglutide, which mimics the GLP-1 hormone that may help regulate blood sugar and reduce appetite. It's administered weekly via subcutaneous injection and was originally developed for type 2 diabetes management. Ozempic may help you feel fuller for longer periods, potentially reducing overall calorie intake. Clinical assessment determines suitability for either medication based on your individual health profile.
Private Prescription Advantages Over NHS Route
Accessing either orlistat or Ozempic privately eliminates NHS waiting times and referral requirements. Our UK-licensed prescribers review your online consultation within 24 hours, compared to weeks or months through NHS channels. Private prescription costs include the consultation, prescription, and medication - no separate GP appointment fees. Both medications require ongoing monitoring, which our prescribers provide through follow-up consultations.

Side Effect Profiles - What to Expect
Orlistat's side effects are primarily gastrointestinal, including oily stools and increased bowel frequency, especially when consuming high-fat meals. These effects can be minimised by following a lower-fat diet. Ozempic may cause nausea, vomiting, diarrhoea, and potential injection site reactions. Both medications require clinical monitoring, and side effects should be discussed with your prescriber during follow-up consultations.
