Buy a Mounjaro Pen for Weight Loss

Once available, you will have the option to request the order Mounjaro weight loss pens online from our registered UK online pharmacy and doctor service. Mounjaro is a prescription weight loss treatment manufactured by Eli Lilly.

What is Mounjaro? Mounjaro is a weight loss treatment intended for individuals with a body mass index (BMI) over 30. It is an injection pen that contains the medication tirzepatide. The Mounjaro pen is a registered trademark of Eli Lilly.

It may also be suitable for individuals with a BMI over 27 who have been diagnosed with weight-related medical conditions, including:

Type 2 diabetes
High cholesterol
Obstructive sleep apnea
High blood pressure
How does it work? Mounjaro contains tirzepatide, an active ingredient belonging to a class of drugs called GLP-1 agonists. GLP-1 agonists regulate hunger and are released by the intestines after a meal.

By functioning similarly to GLP-1, Mounjaro helps control appetite, leading to a feeling of fullness and reduced hunger. This can result in consuming fewer calories and promoting weight loss. Combining Mounjaro with a reduced-calorie diet can further enhance its benefits.

Is it suitable for me? Mounjaro should only be considered for weight loss if you have already attempted and failed to lose weight through exercise and diet alone. Please note that it is not currently available for purchase in the UK. However, there are other GLP-1 drugs like Saxenda, Wegovy, and Ozempic that are available.

How effective is it? When using Mounjaro pens to suppress appetite, patients typically experience a weight loss of approximately 15-20% of their initial body weight upon completing the treatment.

Dosage Mounjaro is administered through an injectable pen. It is injected subcutaneously once a week. The recommended starting dosage is 2.5 mg weekly for four weeks. After one month, the dosage may be increased in 2.5 mg increments up to a maximum of 15 mg once weekly, as tolerated.

If you encounter problematic side effects while increasing the dosage and they persist for two weeks or longer, it is advisable to consult your doctor or pharmacist.

Alternatives The preferred and safest approach to weight loss is adopting a healthy diet and increasing physical exercise.

As alternatives to Mounjaro, other GLP-1 drugs available in the UK include Wegovy, Saxenda, and Ozempic.

For individuals who prefer non-injectable treatments, our weight loss service provides traditional weight loss pills like Orlistat. It contains 120 mg of the drug and works by preventing the absorption of approximately one-third of the dietary fat consumed.

How it works: Suppresses appetite

Effectiveness: Average patient experiences a 15-20% weight loss

Side effects: Common side effects may include fatigue, dizziness, and insomnia

What’s the difference between Mounjaro and Zepbound?

They are exactly the same medicine containing the same active ingredient (tirzepatide) and work in exactly the same way. The difference is the name: Zepbound is the US name for the weight loss management medicine, whereas in the UK it’s licensed under the name Mounjaro. Zepbound is not licensed in the UK.

How does Mounjaro work?

The active ingredient in Mounjaro is called tirzepatide.

Tirzepatide works on two different hormonal receptors: glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). You may have heard of GLP-1 from other weight loss injections.

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.

By mimicking the effects of both these naturally occurring hormones, Mounjaro has been shown to have greater weight loss potential than medicines that work on GLP-1 alone.

How to manage the side effects of Mounjaro

Common Mounjaro side effects should be mild and are likely to lessen or even disappear after your body gets used to the treatment. We understand that it’s still tough to live with these discomforts though and so we’ve put together some tips for managing these where possible:

• Make sure to inject yourself with the treatment at the same time and day each week so your body has a regular interval between each dose
• Stay hydrated, sipping water and other clear liquids if you’re experiencing nausea, vomiting or diarrhoea. It may also help to eat smaller meals more regularly and avoid anything that smells or tastes too strong
• If you’re struggling with constipation, increase your fibre intake, stay well hydrated and try eating small fruits such as prunes, figs or grapes. Make sure you’re also getting regular activity, such as going on short walks
• To ease a headache, spend time in a quiet space to relax, take a simple pain relief medicine like paracetamol, drink plenty of water, and try relaxation techniques such as meditation and DIY scalp massage

Where should I inject Mounjaro?

The best places to inject Mounjaro are ones with the most fat. These are: your tummy (although make sure to inject more than 5cm away from your belly button); the front of your thighs; or your upper arms. It’s important that you change injection sites regularly. You can inject in the same area (e.g. tummy) but choose a different spot in that area each time.

How long does it take for Mounjaro to work?

Mounjaro should start working straight away, but it could take several weeks until it has a noticeable effect on regulating your blood sugar level and impacting your appetite and eating habits.

Can I switch from Wegovy to Mounjaro?

If you’re using Saxenda or Wegovy, you’ll need to wait 1 month before switching to Mounjaro. This is called the 'washout' period, and gives the body time for the first drug to leave the system. All patients using Mounjaro for the first time will start with 2.5mg. Keep in mind, Mounjaro may not be suitable for you (even if you're using another weight loss medicine). We’ll assess if it’s right for you during your consultation.

Which treatment should I choose, Wegovy or Mounjaro?

Wegovy and Mounjaro are both weekly injection pens and work in similar ways to aid weight loss. Mounjaro has proven more effective in clinical trials, as it works on GLP-1 and GIP hormones, whereas Wegovy only works on GLP-1. However, Mounjaro is a new medicine in the UK so we don’t have as much safety data on it compared to other medicines in the long term. Deciding if or which medicine is right for you will depend on different factors, which we’ll assess during your consultation. If you’re already on Wegovy (or Saxenda) and losing weight, we recommend you keep using it. Keep in mind, weight plateaus are normal on your weight loss journey.

What are the main side effects of Mounjaro?

Mounjaro can cause some side effects to occur. Very common ones are gastrointestinal in nature: nausea, vomiting, diarrhoea and constipation. These are mainly seen with dose increases, and tend to settle with time.

Other common side effects could include: fatigue, feeling lightheaded, excess wind (flatulence), gallstones, gastroesophageal reflux, injection site reactions, hair loss and hypoglycemia in patients with type 2 diabetes.

In rare cases, there can be serious side effects, such as:

Pancreatitis – if you develop severe abdominal pain, with or without persistent vomiting, this may be a sign of pancreatitis and you need to get medical help immediately.

Anaphylaxis – if you experience difficulty breathing, swelling of the face, lips or tongue and difficulty swallowing, you may be having a severe allergic reaction (anaphylaxis) and you must seek immediate medical help.
