What is Mounjaro?

Mounjaro (Tirzepatide) is used to treat adults with type 2 diabetes mellitus by reducing the level of sugar in the body only when the levels of sugar are high.

Mounjaro is also used for adults living with obesity (BMI ≥30) or overweight (BMI ≥27) who also have weight-related medical problems like high blood pressure, high cholesterol or heart problems to help them lose weight and keep it off. It should be used with a reduced-calorie meal plan and increased physical activity.

How does Mounjaro work?

The active ingredient in Mounjaro is called tirzepatide.

It’s the First and Only licensed glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist in the UK. It’s dual action causes you to feel less hungry and prevent cravings. It also slows down the emptying of the stomach to keep you feeling fuller for longer.

The action of GIP potentiates the action of the GLP-1 resulting in a much greater weight loss.

Mounjaro has been shown to have greater weight loss potential than medicines that work on GLP-1 alone eg Saxenda and Wegovy.

How effective is Mounjaro?

Clinical trials have shown that patients could achieve at least 20% weight loss after using Mounjaro for 52 weeks when used with healthy changes to their lifestyle.

How do I take Mounjaro?

You can use your pen at any time of the day, with or without meals. You should use it on the same day each week if you can. To help you remember when to use Mounjaro, you may wish to tick the day of the week when you inject your first dose on the box that your pen comes in, or mark it on a calendar.

You might find it helpful to get into a routine, like taking it on a Monday just before bed.

Very common ones are gastrointestinal such as nausea, vomiting, diarrhoea and constipation. These are mainly seen with dose increases, and lessen as your body gets used to the medication.

Other common side effects may be fatigue, feeling lightheaded, excess wind (flatulence), gallstones, gastroesophageal reflux, injection site reactions, hair loss and hypoglycemia in patients with type 2 diabetes. However, we only supply those whose type 2 diabetes is controlled by diet alone.

Serious side-effects can occur rarely and include:-

Pancreatitis where you may experience severe abdominal pain, with or without persistent vomiting, and you would need to get medical help as soon as possible.

Anaphylaxis where you may experience difficulty breathing, swelling of the face, lips or tongue and difficulty swallowing. This is a severe allergic reaction (anaphylaxis) that requires you to go to A&E immediately.
