Important Information - Mounjaro weight loss Injection

We have received many requests to make appointments with clinicians for the Mounjaro weight loss injection to be prescribed. 

In Northamptonshire Mounjaro is currently not available on NHS prescription for weight loss. This is understandably leaving patients feeling disappointed and frustrated.

We are aware that many patients are obtaining Mounjaro through private organisations and although they may notify us that you have been prescribed the injection , the safe prescribing and monitoring of this medication remains the responsibility of the private organisation and not the GP practice. Please ensure all medical history and medications have been fully declared to the prescriber, to enable them to make a safe decision whether this medication is suitable for you.

Please understand that GP practices must follow the guidelines set by our local ICB and NHS England.

We can certainly support you for weight and lifestyle management in other ways.

Mounjaro weight loss injection and Contraception

If you're using tirzepatide (Mounjaro) and taking the contraceptive pill, you should use an additional method of contraception, such as a condom. This is because your body may not absorb the contraceptive pill while using the tirzepatide (Mounjaro). More information about these medicines and contraception is available by visiting here.

Mounjaro weight loss injection and HRT

If you're using tirzepatide (Mounjaro) and taking hormone replacement therapy (HRT), you should consider using patches or gels which are absorbed through the skin. This is because your body may not absorb the HRT whilst using the tirzepatide (Mounjaro). For more information about taking tirzepatide (Mounjaro) and HRT, speak to your doctor.
