Prescriptions for Mounjaro jabs, to help people lose weight, will be available at GP surgeries in England from today - but only for those who meet very strict criteria.

“The medication comes with a patient information leaflet listing common side effects, including feeling sick, indigestion, constipation, and diarrhoea. There can be some more serious side effects, such as low blood sugar, gallstones and inflammation of the pancreas (pancreatitis).

A mass rollout of weight loss injections begins across the NHS on Monday, with GPs able to prescribe Mounjaro for the first time. The drug, also known as tirzepatide and manufactured by Lilly, is an antidiabetic medication that works by lowering blood sugar levels and slowing down the digestion of food.
