What is Mounjaro?
Mounjaro is a once-weekly injection designed to support weight loss and help with weight management. It works by reducing cravings, lowering your appetite, and helping you feel fuller for longer, even when you’re eating less.
Mounjaro’s main ingredient is called tirzepatide. It works on two natural hormones in the body: GLP-1(glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). Most weight loss injections only work on GLP-1, but Mounjaro is different because it works on both. This makes it a “dual agonist” treatment, and research shows it can lead to more weight loss than other options.
Through multiple clinical trials, Mounjaro has been proven safe and effective for long-term use in the UK, and is only available on prescription through licensed providers like Chemist4U.
“Mounjaro works best when paired with lifestyle changes, like eating a balanced diet, staying active, and building healthy habits you can stick with. Combining these with your treatment plan gives you the best chance of seeing results and reaching your weight loss goals safely. At the end of the day, healthy habits support weight loss and help you maintain it for the long term.”

How It Works
Mounjaro weight loss pens mimic the action of GLP-1, a natural hormone produced in the gut. This innovative treatment promotes significant weight loss for patients by acting similarly to GLP-1. Its two main effects are;
- It helps regulate appetite, making it easier to eat less
- It makes you feel fuller for longer
Both actions lead to eating fewer calories, which results in weight loss. Focusing on a reduced-calorie diet can amplify the benefits.
How Does Mounjaro Work In The Body
The active ingredient tirzepatide works by activating the receptors of 2 natural incretin hormones: GIP and GLP-1. Both of these hormones affect your appetite by slowing down the emptying of the stomach after a meal. They also send signals to your brain to reduce your appetite after eating. This action creates a feeling of being full and so makes you feel less hungry, even when you have eaten less, which can aid in weight loss.
For diabetic patients, Mounjaro increases the production of insulin, which is released into your body to lower blood sugar levels.
Worried about self-injection?
“Self-injecting medication may be an uncomfortable idea for many people. But, Mounjaro injections are not the same as ones that might be used for things like vaccinations. Mounjaro comes in an easy-to-use injection pen, which isn’t the same as using a standard injection needle. Mounjaro uses a much smaller needle than the one for vaccinations and the liquid isn’t pushed by hand.” Dr Nasak Isnaf
Where should I inject Mounjaro?
Mounjaro can be injected either in the abdomen or thigh. Select an injection site that you feel most comfortable with. Switch injection sites weekly and divide the chosen area into four sections which will be your injection sites. Inject at least one finger width away from the last injection. If injecting in the abdomen, inject at least 5cm away from the navel.
How to Inject step by step
- Wash your hands using water and soap.
- Prepare the pen and check that it’s not expired or damaged and the liquid looks as it should.
- Attach a new needle to the pen.
- Slowly turn the dose knob until you hear 2 clicks.
- Prime the pen to release air bubbles and make sure it’s working correctly.
- Adjust the dosage to ‘1’.
- Insert the needle, push down the dose knob and count slowly to 5.
- Pull the needle out of your skin and check if the dose count is back at ‘0’.
- Remove the needle and replace the pen cap.
Make sure you take your injection at the same time each week (when exactly is up to you) to get the best effect and try not to forget any doses.
How long do I have to stay on Mounjaro?
How long you can stay on Mounjaro depends on how much weight you need to lose to achieve a healthy BMI and if you need help to maintain that weight. If you are not able to lose weight on Mounjaro, a doctor can recommend alternatives for you.
How often should Mounjaro be taken?
Mounjaro should be taken once a week. It can be taken at any time of the day, with or without food. You should select a day and time that is convenient or easy for you to remember. You may find it useful to set a reminder on your phone to ensure you do not miss a dose.
If you want to change the day of the week you use Mounjaro, you’ll need to leave at least 72 hours (3 days) between doses, and then you should carry on taking it weekly. It’s important that you don’t do this often, or it could decrease the effectiveness of your treatment.
What happens if you miss a dose?
Missed doses should be taken within 96 hours (4 days) of the missed dose. If it is outside of 96 hours, miss the dose and continue to your next scheduled dose. Speak to your doctor if you miss several doses, as you may need to start the dosage schedule again.
What Mounjaro Dosage are available ?
Mounjaro is available in 6 dosages, which you move up over time.
The dosages of Mounjaro available are:
- 2.5mg
- 5mg
- 7.5mg
- 10mg
- 12.5mg
- 15mg
You will start your journey with Mounjaro on the lowest dose of 2.5 mg, which needs to be injected once a week for 4 weeks. If the medication works well for you, you can increase your dose to 5mg for 4 weeks. Depending on progress, you can either stay on this dose or you can increase the dose in 4-week blocks by 2.5mg each time.
Don’t increase your dosage earlier than 4 weeks and speak to your doctor if you get side effects on your current dose. Never take more than the maximum dosage of 15mg, as this can lead to severe side effects.
