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.

NHS England says while the long-term plan is for the jabs to be more widely available, a staggered approach is needed to reach those most at need, manage GPs' workload and NHS resources.

Some GP practices are already warning patients who do not meet the criteria that they should not book appointments to discuss the jabs right now.

Pharmacy trade organisations say they are concerned that demand for Mounjaro from GPs will outstrip supply.

Mounjaro, or tirzepatide, is a weekly injection that was initially licensed to help treat type 2 diabetes, but is now also prescribed to help those with obesity lose weight.
