Naltrexone and bupropion is a combination medication that has been prescribed for weight management in overweight and obese patients. Bupropion is an antidepressant medication also known to decrease appetite in individuals, whereas naltrexone is usually given to block the effects of narcotics or alcohol in people with addiction problems. Naltrexone is part of the class of drugs known as opiate antagonists. It is also known to restrain hunger and cravings for food. Contrave can also be termed as an anorexiant, which is very helpful in weight management. Both these medicines work together on two separate parts of the brain to reduce appetite and cravings.

It should be used in conjunction with diet and exercise.

Contrave is an FDA-approved drug available only with a prescription. It is a weight loss medication that is usually beneficial in adults who are overweight or struggling with obesity to lose weight and keep it off. Contrave is known to work on two important areas of the brain, the hunger center and the reward system, by reducing hunger and helping to control food cravings. Losing weight and maintaining an ideal body weight can reduce many medical conditions that are associated with obesity, including diabetes, high blood pressure, heart disease, and shorter life span.

One should note that this medicine is not to be used for the treatment of depression or any other psychiatric condition in an individual. Also, most of the drugs that belong to the opiates class should not be taken for more than seven to ten days before one starts naltrexone.

Your doctor is the best guide for when to start the medication and the required dosages, so keep your doctor informed with regards to any drug intake.

However, it is postulated that, because elderly patients may have decreased or compromised renal function due to old age, dose adjustment should be considered and the drug must be used with caution.
