Contrave and Duromine have different mechanisms to GLP-1 receptor agnonists. Duromine (phentermine) is a short-term appetite suppressant that works by stimulating the central nervous system taken daily. Duromine can have more intense side effects such as increased heart rate, dry mouth, insomnia, and anxiety.
Contrave is also taken daily and contains two medicines – naltrexone and bupropion, which together help regulate hunger and cravings. Contrave can cause side effects like nausea, headache, dry mouth and more. Based on research, Wegovy may lead to more weight loss than Duromine and Contrave.
