Naltrexone is used to treat opioid and alcohol abuse in higher doses and is used off-label to treat pain and inflammation in lower doses. Used alone for weight loss, researchers have come to inconsistent conclusions about its efficacy as an appetite suppressant. Low-dose naltrexone supports immune function and increases endorphin release.
Patients can buy Naltrexone for appetite reduction with an included prescription consultation with a doctor.

How Does Naltrexone Work?

Reduce Cravings and Hunger

Naltrexone is an opiate antagonist. Bupropion is a noradrenergic/dopaminergic antidepressant. Bupropion and naltrexone work together in the hypothalamus to reduce cravings and hunger. They activate POMC neurons in the hypothalamus, a brain region that produces a neurotransmitter that decreases the desire to eat. In the mesolimbic area of the brain – a reward center in the brain that is stimulated by pleasurable activities such as eating – bupropion and naltrexone can regulate these feelings of pleasure, reducing cravings to eat.

In three studies with over 4,000 participants who were overweight or obese and also had high lipid levels or high blood pressure, participants taking naltrexone and bupropion combined with a diet and exercise program lost more weight than those who were taking a placebo with the diet and exercise program. The most common side effects were nausea, constipation, and headache.
