Summary
Women using weight-loss injections like Mounjaro and Wegovy are advised to use effective contraception due to potential risks for unborn babies. These drugs help reduce appetite by mimicking hormones and are available through the NHS for people with severe obesity, but private purchase is possible. Trials show Mounjaro may lead to greater weight loss compared to Wegovy, though weight can be regained once treatment stops.
