It’s important to understand what Mounjaro is and to take it as directed. Make sure you read our treatment summary. We've also prepared some Mounjaro FAQs to supplement the Patient Information Leaflet and Mounjaro user guide that comes with your supply.
Tirzepatide
KwikPen (injectable)
The active ingredient in Mounjaro is called tirzepatide and it stimulates two different naturally occurring hormonal receptors: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). Other weight loss injections like Ozempic and Wegovy work on GLP-1 alone, whereas Mounjaro combines with GIP to increase the weight loss potential.
GLP-1 helps to regulate blood sugar levels, which in turn talks to the brain to make you feel less hungry and prevent cravings. It also slows down the emptying of the stomach to keep you feeling fuller for longer.
GIP regulates energy balance in brain and fat cells, enhancing the GLP-1 effect of suppressing your appetite and improving sugar control.
You’ll take Mounjaro using the easy-to-use Mounjaro KiwkPen. You’ll use the KwikPen once a week, on the same day, under the skin (subcutaneously) of your stomach, thigh or upper arm. It’s important to change injection sites regularly. You can inject in the same area but choose a different spot in that area each time.
The KwikPen comes pre-filled with 4 doses, lasting 4 weeks. When you first start taking Mounjaro, the starting dose is 2.5mg once weekly for 4 weeks, increasing to 5mg once weekly for the following 4 weeks. Dosage can then increase every month as your treatment continues, with a maximum weekly dosage of 15mg. It’s important to note that not everyone will need the higher doses for Mounjaro to be effective.
Mounjaro is designed as a long-term treatment and can be prescribed for up to 2 years. You should expect to see weight loss results from around 6 months with continuous use, and maximum weight loss generally around the 12-18 month mark (depending on medication used, dosage levels and other lifestyle adjustments).
Studies have shown that by week 72 people can achieve a 15% weight loss with 5mg, 19.5% weight loss with 10mg and 20.9% weight loss with 15mg.

Start your weight loss journey with Morrisons Clinic
Mounjaro will start working in your body straight away, but it might take a few weeks until you notice an effect on it impacting your appetite and eating habits.
Mounjaro is designed as a long-term treatment and can be prescribed for up to 2 years. You should expect to see weight loss results from around 6 months with continuous use, and maximum weight loss generally around the 12-18 month mark (depending on medication used, dosage levels and other lifestyle adjustments).
You’ll start Mounjaro on a 2.5mg dose and build up to the higher doses over time. The maximum dose is 15mg, however not everyone will need the higher doses for Mounjaro to be effective. Studies have shown that by week 72 people can achieve a 15% weight loss with 5mg, 19.5% weight loss with 10mg and 20.9% weight loss with 15mg (SURMOUNT-1 trial).
Because Mounjaro can be prescribed for up to 2 years, we advise you to view this as a long-term treatment alongside healthier diet & lifestyle changes (including regular exercise). How long you take it will depend on your weight loss goals and individual circumstances. It’s important to note that when you stop Mounjaro, to maintain your weight longer-term, you need to adopt lifestyle changes and regular exercise.
Treatment prices will start from £129 per month for your first order of Mounjaro; including your medication, at-home delivery and the supportive oversight of our clinical team. Subsequent 2.5mg orders will then be £159. As your treatment progresses and your monthly dosage increases, the monthly price may also increase.
Common side effects include nausea, headaches, stomach upsets (diarrhoea and vomiting) constipation, tiredness, acid reflux and indigestion symptoms, gallstones, dizziness, hair loss and reactions at injection sites.
Uncommon and rare side effects include increased heart rate, increased gastric enzyme levels, pancreatitis, angioedema and anaphylactic reactions.
We expect some common side effects to subside within the first few weeks, however if you experience any of the rarer side effects, you should stop the injections immediately and seek medical help.
After completing a successful consultation, your 4-week supply of Mounjaro will be delivered via the Royal Mail Tracked 24 option. Your package will include:
Your injections and necessary needles for administration, thoughtfully packed with insulation material (a wool-type material) and ice gel packs to ensure optimal temperature during transit.
A sharps bin for the safe disposal of used needles.
Because you’ll buy a 4-week supply at a time, we recommend you re-order as soon as you’ve taken your 3rd dose in each cycle. During your re-order consultation, we’ll ask you to update us on your progress and how you’re getting on with Mounjaro (including regular weight and side effect updates). Our in-house prescribing pharmacists will review your consultation to ensure you’re on-track and Mounjaro is working for you.
Before first use please store Mounjaro in a fridge (2°C to 8°C). It is crucial to avoid freezing the medication and don’t use it if it has been exposed to freezing temperatures.
After first use and once opened, Mounjaro can be stored at room temperature (8°C to 30°C) for up to 30 days. Always keep the pen cap on when the pen is not in use to protect it from light exposure.
You’ll take Mounjaro using the easy-to-use Mounjaro KwikPen. You’ll use the KwikPen once a week, on the same day, under the skin (subcutaneously) of your stomach, thigh or upper arm. It’s important to change injection sites regularly. You can inject in the same area but choose a different spot in that area each time.
Different weight loss medications aren’t interchangeable. If you’re using another weight loss medication, such as Wegovy, you’ll need to wait up to 4 weeks before switching to Mounjaro. Your previous weight loss medication needs to fully leave your system during a 'washout' period. Keep in mind, Mounjaro might not be suitable for you (even if you're using another weight loss medication). We’ll assess if it’s right for you during your consultation.
These weight loss medications are approved for use by the MHRA, the UK government department responsible for ensuring that medicines and medical devices work and are acceptably safe.
Your treatment will be supervised by our qualified pharmacists and clinical team at all times. If you experience any side effects or changes in overall health, you must let us know so we can ensure your safe health & wellbeing.
For women using oral contraceptives – we recommend switching to a non-hormonal contraceptive or a barrier method of contraception for four weeks at the beginning of treatment, and four weeks after each dose adjustment.
They’re all designed to aid weight loss alongside a healthier diet & lifestyle changes (including regular exercise). However, the active ingredient in Ozempic and Wegovy is semaglutide, which only works with the GLP-1 receptor. Mounjaro contains tirzepatide, which stimulates both the GLP-1 and the GIP receptor – this combination has been shown to have greater weight loss potential than medicines that work on GLP-1 alone.
Our clinical team will check in regularly with you via email to see how you are progressing with treatment. Towards the end of your first month, you will receive reminder emails with instructions on how to re-order your next dose. You will be directed to a shorter clinical consultation designed to assess how you are getting on with your treatment and whether or not you need a dosage adjustment. You can also log in to your Phlo Clinic account and re-order this way should you choose. For optimal results, we encourage patients to take a long term view of this treatment on a monthly basis until you reach your weight loss goal.
