Orlistat vs Mounjaro: Key Differences
Orlistat and Mounjaro are entirely different weight loss treatments. Orlistat 120mg is an oral capsule that works in your digestive system by blocking approximately one third of dietary fat absorption. Mounjaro (tirzepatide) is an injectable medication that acts on GLP-1 receptors to reduce appetite and slow gastric emptying. Both require prescription and clinical assessment, but work through completely different mechanisms.

Choosing Your Supply Length
Weight management with orlistat typically requires sustained treatment alongside a reduced-calorie, lower-fat diet. Many patients start with a 4-week supply to assess tolerance, then progress to 8 or 12-week packs for better value. Longer supplies offer significant savings per capsule and reduce reordering frequency. Your prescriber can advise on appropriate treatment duration during your clinical assessment.
