Contrave is a prescription medication that is a combination of two active ingredients: bupropion and naltrexone. It is used as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults who have obesity or are overweight and have at least one weight-related condition.

Bupropion is an antidepressant medication that is also used to help people quit smoking. It may help reduce appetite and increase energy expenditure. Naltrexone is primarily used to treat alcohol and opioid dependence, but in the case of Contrave, it is believed to help reduce food cravings.

The exact mechanism of action of Contrave for weight loss is not fully understood, but it is thought to act on areas of the brain that control appetite and reward pathways.

Contrave is usually taken in tablet form, and the dosage is gradually increased over several weeks to minimize potential side effects. The specific dosage and treatment duration should be determined by a healthcare professional.

Like any medication, Contrave can have side effects. Common side effects may include nausea, constipation, headache, dizziness, dry mouth, and insomnia. Rare but serious side effects, such as increased blood pressure or heart rate, may also occur. It is important to discuss potential risks, benefits, and side effects with a healthcare provider before starting Contrave.
