Mounjaro

Mounjaro Injection

Getting started

Currently we only prescribe Mounjaro for people with Type 2 Diabetes. From 23/6/25 some other people should be able to access this medication on the NHS but this roll-out is going to be delayed slightly. For more details on this have a look at the base of this page.

How to use the Mounjaro Kwikpen

We would recommend watching the video below to see how to use the pen device. Remember the following key points:

  • Keep in the fridge until the pen is in use
  • Once in use it can then be kept at 2-30 degrees centigrade for up to 30 days
  • Do an “air shot” to prime the needle before each dose
  • Count to 5 before removing the needle after a dose has been given
  • Each pen contains four doses

Women of Childbearing age

If you are using Mounjaro (or other GLP1 injections) it is really important that you check what impact this might have on contraception that you might be using. Please read this document from the Faculty of Sexual & Reproductive Healthcare on this subject.

The key points are

  • If you are using Mounjaro you should use a barrier method of contraception (e.g. condoms) in addition to your pill for four weeks after starting the medication, and for four weeks after any increase in dose.
  • If you are switching to Mounjaro from any other GLP-1 agonist then you should use a barrier method of contraception (such as a condom) for four weeks after the switch, and for four weeks after any increases in dose, while also continuing your oral contraception.
  • We don’t know yet if oral emergency contraception is affected by GLP-1 agonists.
  • GLP1 medications should not be taken when pregnant. You should stop them before getting pregnant and the recommended duration of stopping before getting pregnant varies depending on the type of GLP1 you are using. For more details read this document.

Mounjaro for Obesity

From 23/6/25 more people should be eligible for Mounjaro on the NHS. However, the criteria are quite strict and there will be a delay in new people becoming eligible. Locally we first need to work through those people already on the waiting list for bariatric surgery who are now eligible for these injections. We are also waiting to hear how these injections will be delivered and funded in primary care.

The eligibility criteria will be that you need a BMI of 40 or over plus 4 out of the following 5 medical issues:

  • Dyslipidaemia (abnormal fat levels in the blood)
  • Hypertension (high blood pressure)
  • Obstructive Sleep Apnoea (when your breathing stops and starts while you sleep)
  • Cardiovascular Disease (heart and blood vessel disease)
  • Type 2 Diabetes

Each year the criteria will change slightly making more people eligible.
