Contrave is the United States brand name for a weight-management tablet that combines naltrexone and bupropion. There is no medicine called Contrave on sale in the European Union, so Hi-Doctor does not prescribe it — but the identical combination is authorised in the EU under a different brand name.

What it is

Contrave is a tablet combining two older medicines, naltrexone and bupropion, which together act on the parts of the brain that control hunger and food cravings. If you have read about Contrave online, you are reading about the American product, and any website offering to ship Contrave to an EU address is not operating within EU medicines law.
Contrave has no EU marketing authorisation for weight management, so it cannot be prescribed or dispensed here for that purpose. The identical combination of naltrexone and bupropion is authorised in the EU — under the brand name Mysimba. See the Mysimba page.

How it works

Naltrexone and bupropion act together on the brain areas that control hunger and food cravings. Naltrexone blocks the mu-opioid receptor; bupropion acts on the dopamine transporter and the noradrenaline transporter.

What the studies reported

The pivotal trial is COR-I, published in The Lancet and registered on ClinicalTrials.gov as NCT00532779. All participants also followed a reduced-calorie diet and exercise programme, and a large proportion of people randomised did not complete the 56-week trial, which makes the average figures harder to interpret. Because naltrexone blocks the mu-opioid receptor, this combination is not taken with opioid pain medicines — the naltrexone would block the pain relief.

What has been reported

Because naltrexone blocks the mu-opioid receptor, Contrave-equivalent medicines are not combined with opioid medicines.

Common questions

No. There is no medicine called Contrave on sale in the European Union. The identical combination of naltrexone and bupropion is authorised in the EU under the brand name Mysimba, and any website offering to ship Contrave to an EU address is not operating within EU medicines law.
Mysimba contains exactly the same active ingredients — naltrexone and bupropion — at the same doses as the US product Contrave. It is the EU-authorised version, assessed by the European Medicines Agency for weight management.
Bupropion acts on the dopamine transporter and the noradrenaline transporter. Anyone currently taking an antidepressant or other medicine that acts on the central nervous system should discuss this with the reviewing doctor, who checks all current medication before prescribing.
The COR-I trial did not follow weight after treatment stopped. As with other weight-management medicines, weight that was lost may be regained if the dietary and exercise changes made alongside treatment are not sustained.

What can I take instead?

A licensed doctor decides case by case — we never prescribe without evaluation. Options a doctor may consider for weight management:

Semaglutide (Wegovy / Ozempic)

Weekly GLP-1 receptor agonist. A doctor may prescribe it if your BMI and history match the indications. Requires follow-up.

Tirzepatide (Mounjaro)

Dual GLP-1/GIP agonist. Assessed by the doctor based on comorbidities and BMI.

Liraglutide (Saxenda)

Daily GLP-1 agonist. Indicated in selected patients with elevated BMI after medical evaluation.

Orlistat 120mg

A fat-absorption inhibitor. Approved in the EU with published peer-reviewed trial results; a non-GLP-1 alternative a doctor may consider.

How Hi-Doctor handles it

We don’t prescribe Contrave today, but our doctors can review your case and propose an equivalent weight-management treatment with EU authorisation — starting with Mysimba, the EU-authorised version of the same combination. See how it works for the consultation process, and pricing for the consultation fee — medication is paid separately, at a pharmacy of your choice. For other options, see Orlistat and the full treatment areas Hi-Doctor covers.

Weight-loss consultation

Answer the weight-loss questionnaire and a registered doctor reviews it. They decide whether treatment is appropriate, which one, and at what dose — and declining is a normal outcome. See what it costs and how the review works.
