Learn more about reporting side effectsAbout Mysimba
Mysimba contains a combination of bupropion hydrochloride, an antidepressant, and naltrexone hydrochloride, an opioid antagonist as its active ingredients, both of which help with weight loss.
Mysimba is an anti-obesity medication, used with a reduced-calorie diet and increased physical activity, for weight management in adults with a body mass index (BMI) of 30 kg/m2, or 27 kg/m2 to < 30 kg/m2, with one or more weight-related health conditions, such as high blood pressure, high cholesterol, or type 2 diabetes. It is thought the naltrexone/bupropion combination reduces a person’s appetite and increases the amount of energy used up by the body.
NowPatient offers Mysimba as a treatment for weight loss only, following an online consultation with a prescribing clinician.
