Mounjaro KwikPen key facts

The pen device is designed to allow a person to easily self-inject Mounjaro at home once a week. It’s injected just under the skin with a small, thin needle. You can choose to inject in either your stomach area, thigh or upper arm – whichever you prefer.

Each pen lasts one month and comes preloaded with 4 doses (4x once weekly injections).

Always make sure to read the user instructions and the Patient Information Leaflet that comes with the device.

How do Mounjaro injections work?

Mounjaro injections work by mimicking two hormones your body naturally makes: GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). These hormones help control blood sugar levels and reduce hunger.

How Mounjaro works with your body

Mounjaro works with your body to help you lose weight. It’s most effective when used alongside a balanced, healthy diet and increased physical activity or exercise.

Helps your pancreas make insulin: After you eat, Mounjaro tells the pancreas to release more insulin, a hormone that lowers blood sugar. Improving how your body uses insulin stops it from storing excess sugar as fat.
Lowers the amount of sugar your liver makes: When your liver isn’t releasing sugar into the blood for energy, your body has to rely on fat stores for energy. This process, where the body breaks down its fat cells, is called lipolysis and leads to weight loss.
Makes you feel full: Mounjaro works on the part of the brain that controls hunger, helping you feel full sooner and reducing how much you eat.
Slows digestion: Mounjaro makes food move more slowly through the stomach, which helps prevent big spikes in blood sugar after meals and keeps you feeling full.

Understand who can use Mounjaro

Mounjaro is a prescription-only medication licenced in the UK for weight loss. This means there are guidelines on who it’s suitable for, based on a range of health factors and likelihood of successful treatment results.

It might be a suitable treatment for you if you meet the below initial eligibility criteria:

Adults aged 18-85
Those with a BMI above 30
Those with a BMI above 27 and a weight-related condition such as high blood pressure, high cholesterol, heart disease, type 2 diabetes and some other weight-related health conditions

This list is only intended as an indicator for who might be suitable for treatment. The doctor will complete a full medical review of your consultation to determine your individual suitability for treatment.

Use this NHS tool to calculate your BMI.

Possible Mounjaro weight loss results

Studies have shown a possible weight loss of up to 22.5% over 72 weeks. Mounjaro is a long-term weight loss treatment and not just a short-term option, you should start to see weight loss within the first 4-6 weeks.

Weight loss examples

One medical trial (there have been five so far) involved 2,539 people using either no Mounjaro, 5mg, 10mg or 15mg Mounjaro once a week for 72 weeks (just over 1 year and 4 months).

Everyone using Tirzepatide (Mounjaro) on the trial started with 2.5mg once weekly for the first four weeks. During this time, they lost around 3% of their starting body weight.

Tirzepatide users on the trial went up to 5mg once weekly for the next four weeks (weeks 5-8). During this time, users reached an average of 5-6% weight loss.

For weeks 9-12, some people stayed on 5mg of Mounjaro, and some moved up to 7.5mg weekly. Most people lost around 8% of their starting weight by week 12, regardless of whether they were on 5mg or 7.5mg.

Remember, studies show an example of what’s possible, but every weight loss journey is unique.

There is a small chance you might experience extra or stronger side effects when taking your next dose early, especially if you are also going up a strength. This isn’t a problem, but you should be aware.

Where is the best place to inject Mounjaro?

Whether you inject in your abdomen, thigh or arm doesn’t affect the effectiveness of the drug.

It is your personal preference. Some people find that the abdomen is the least painful of the three injection sites, whereas the upper leg allows more visibility for injecting compared to the arm, which is a less visible option.

If you choose the same injection site, you should make sure it’s at least one fingertip space away from where you injected the week before.

Is a red bump or liquid on my skin normal after injecting?

Red bump

Yes, up to 1 in 10 people will experience redness, itching and swelling on the injection site. This is normal and these injection site reactions will disappear as your body gets used to the medicine. You can take an anti-histamine tablet and apply a cooling compress to the area to help treat this.

If for any reason these reactions become more severe, you should contact your healthcare provider right away as it may be a sign of a more severe allergic reaction.

Surplus liquid

Seeing liquid on the skin after injecting Mounjaro is normal and is commonly referred to as leakage or backflow.

It can be caused by many factors such as injection speed, volume of solution or the angle you insert the needle.

You must ensure that you leave the needle in the skin at least 3 seconds after injection, this should help prevent so much liquid on the skin. Never give yourself a second dose, no matter how much liquid is left on your skin.

When should I increase my dose of Mounjaro?

This all depends on how well you tolerate the dose you are on. If you are taking any strength of Mounjaro, you have no side effects and still losing weight, we advise that you stay on that dose.

On the other hand, if you have increased your dose of Mounjaro and you are experiencing unbearable side effects, you may want to consider reducing your dose.

If you have taken a dose of Mounjaro for at least 4 weeks, have no side effects and have stopped experiencing weight loss, you may have hit a weight loss plateau and could consider increasing your dose. You should reflect on your eating and exercising first.

When you request a change of dose our healthcare professionals will consider this and help you make the best and safest decision for you.

Is there an ideal diet to follow during weight loss treatment?

Whilst there isn’t a specific diet to follow, it’s recommended that you follow a healthy & balanced diet. Focus on creating balanced meals that contain adequate protein and fibre. Make sure to drink plenty of fluids too.

You should drink at least 6 - 8 servings of water a day (one serving is a 250ml glass).

Try to avoid drinking with meals as this can cause you to feel too full and stop you from being able to eat your meal. We advise drinking water at least 30 minutes before or after a meal.

Aim for 3 meals a day, with snacks in between if needed, to provide your body with steady energy throughout the day. A balanced meal should look like:

Filling half your plate with non-starchy vegetables, salad or fruit
Filling a quarter with wholegrain carbohydrates
Filling the other quarter with lean protein
Include a small serving of healthy fats within your meal

What vitamin supplements should I take on Mounjaro?

While losing weight there may be a risk of not consuming all of the vitamins you need caused by eating less food. We strongly recommend taking a daily multivitamin to ensure you are getting all you need.

Some people have reported temporary hair loss with weight loss, this can be supported by a daily skin, hair and nails vitamin-containing biotin, zinc and selenium.

You may want to also make sure you are getting enough vitamin B and iron to reduce tiredness caused by eating fewer calories.

What is the best exercise to do on Mounjaro?

Any exercise is great but to get the best results from your weight loss journey you should consider alternating different forms of exercise. Such as light aerobatic exercises like walking and brisk walking or jogging and strength training such as lifting weights and doing squats help build muscle and boost your metabolism.

Do I have to stay on Mounjaro long term?

According to studies, Mounjaro is most effective if it is taken continuously for 12 months or longer.

After 12 months, you can also decide whether you will stop treatment or stay on a maintenance dose.

You can stop Mounjaro at any point in your treatment, this is completely up to you. If you stop treatment we advise that you continue to maintain a healthier lifestyle to prevent any unwanted weight gain.

You can speak to a member of our trained team if you have any questions about stopping or continuing your treatment with Mounajro.

What happens when you stop taking Mounjaro?

When you stop using Mounjaro, you will notice your appetite increasing or returning in full within a few weeks. If you haven't made any necessary lifestyle adjustments, you could regain some of the weight you lost. Regular exercise and healthy eating are two ways to stay on top of your weight loss and prevent regaining it.

There are not any reports of people experiencing withdrawal symptoms when discontinuing the use of Mounjaro. The medicine can take up to 25 days to entirely leave your system, so any side effects you are experiencing should also go by then.
