It depends on the dose. Orlistat 60mg (branded as Alli) is available over the counter at pharmacies without a prescription. The higher 120mg dose requires a prescription, which you can obtain through a GPhC-registered online pharmacy via a digital consultation. All prescription providers listed on MedEazy include an online prescribing service.

Orlistat works by blocking approximately one third of the fat you eat from being absorbed by your body. The undigested fat passes through your digestive system and is excreted. It is most effective when used alongside a reduced-calorie, low-fat diet and regular exercise.

The most common side effects relate to digestion and include oily or fatty stools, frequent or urgent bowel movements, and flatulence. These are typically worse if you eat high-fat meals. Side effects usually improve as you adjust to a lower-fat diet. Always read the patient information leaflet and consult your prescriber if concerned.

Clinical studies show that patients using Orlistat 120mg alongside diet and exercise lost an average of 5–7% of their body weight over 12 months, compared to around 4% with diet and exercise alone. Results vary depending on dietary adherence and individual factors. Orlistat tends to be most effective in combination with meaningful lifestyle changes.
