Orlistat vs Mysimba
Orlistat and Mysimba are both oral weight-loss medicines, but they are used in very different ways. Orlistat is linked to how fat from meals is digested. Mysimba combines naltrexone and bupropion in a prolonged-release tablet, so the health checks and medicine-interaction questions are different.
Different medicines, different checks
Orlistat is meal-linked
Start with meals, fat intake, bowel side effects and whether the service explains how to take it clearly.
Mysimba has different checks
Look for blood-pressure, medicine, opioid-use, seizure-history, mental-health and dose-build-up checks.
Price is only one part
Reviewed prices range from £17.39 to £143.95, but fees, supply length and availability can change.
Price alone is not enough
It is tempting to treat Orlistat and Mysimba as two tablet prices. That misses the useful part of the decision. Orlistat is closely tied to meals and fat intake. Mysimba is a combined medicine with a gradual dose schedule and more medicine-history checks.
A better comparison includes active ingredient, how the medicine is used, review points, side effects to discuss, clinical checks and total cost.
Orlistat and Mysimba side by side
This table keeps the two medicines separate so the comparison is not reduced to a single monthly price. It is not a recommendation for either medicine.
| Compare | Orlistat | Mysimba |
|---|---|---|
| What it is | A capsule containing orlistat, a medicine that works in the gut by reducing how much fat from meals is absorbed. | A prolonged-release tablet containing naltrexone and bupropion, with different suitability and medicine-interaction checks. |
| How it is taken | Usually taken with meals that contain fat, alongside diet and activity changes. | Usually built up gradually over several weeks, alongside a reduced-calorie diet and increased physical activity. |
| What usually matters | Meal routine, fat intake, bowel side effects, pack size, pharmacy supervision and clear instructions for use with food. | Daily tablet schedule, blood pressure, current medicines, mental-health history, opioid medicines, interactions and follow-up review. |
| Availability context | Orlistat is listed by the NHS as a medicine used for weight management when suitable. Lower-dose pharmacy products such as Alli and Orlos are also mentioned by the NHS. | NICE says naltrexone-bupropion is not recommended for routine NHS use for managing overweight and obesity, so private availability can look different from NHS availability. |
| Review timing | The NHS says orlistat should usually only continue beyond 3 months if enough weight has been lost. | NICE describes stopping naltrexone-bupropion after 16 weeks if at least 5% of initial body weight has not been lost. |
| Reviewed price range | £17.39 to £74.99 across 31 reviewed Orlistat price entries. | £97 to £143.95 across 19 reviewed Mysimba price entries. |
Orlistat questions usually start around food
The NHS explains that orlistat reduces how much fat from food is absorbed. That is why low-fat eating, meal timing and bowel side effects are central to comparing Orlistat services.
Mysimba checks focus more on medicines and health history
Mysimba contains naltrexone and bupropion. A careful service should ask about current medicines, blood pressure, seizure history, opioid medicines and other health factors before treatment is considered.
