What is Mounjaro and How Does it Work?

Mounjaro is a treatment for weight loss. It is available as a prefilled pen that you inject yourself once a week. Mounjaro is the UK-licensed version of Zepbound, which is licensed in the US. 

The active ingredient in Mounjaro is Tirzepatide. Trizepatide attaches to receptors of hormones called GIP and GLP-1. GLP-1 and GIP are produced naturally in the body when you eat something. 

Once tirzepatide is attached to the receptors, it mimics the same way GIP and GLP-1 work and tells the body to increase the amount of insulin from the pancreas. This helps the body regulate (control) blood sugar levels and reduce the amount of food you eat. It also helps: 

  • The body releases insulin (hormone) when blood sugar levels are high 
  • Stop the liver from making and releasing too much sugar 
  • The body removes excess sugar (glucose) from the blood
  • Reduce how much food you eat 
  • Slow down how fast food leaves the stomach

How Effective is Mounjaro?

When using Mounjaro kwikpens to suppress appetite, you can expect to lose around 15-20% of your initial body weight after completing treatment with a balanced diet and exercise. This is the most effective of all the released GLP-1 medications so far including Wegovy.

These figures have been achieved by patients who have maintained on the highest strength of Mounjaro, which is the 15mg strength.

In a trial carried out by Eli Lilly, it was shown that patients who maintained dose at 10mg lost an average of 17% of their body weight whilst patients who maintained dose at 5mg, lost around 15%.

Weight Loss Pills & Capsules

  • Xenical 120mg: The brand name version of Orlistat. These tablets contain the active ingredient orlistat and break down dietary fats into smaller pieces before your body absorbs them. 

The Science Behind Mounjaro 

Mounjaro has been approved for use by the FDA (American regulatory authority) and the UK MHRA and has been proven to be safe and effective for treating weight loss in obese patients and patients with type 2 diabetes. 

Data has shown that patients can experience weight loss in as little as 4 weeks. Further weight loss can be observed until the study ends at 40 weeks. Patients at an optimal dose experienced a total weight loss of ~ 20% of their starting weight after 40 weeks.

Mounjaro Weight Loss Pen Dosage & Directions of Use

How to Use a Mounjaro KwikPen 

Mounjaro comes in a pre-filled pen that is designed to deliver the medication under your skin (subcutaneously). The pen comes with a complete guide on how to use it. It is important to read and understand it before using the pen. To take your weekly dose of Mounjaro, follow these steps: 

  • Remove the KwikPen from the packaging, and check the expiration date
  • Next, make sure that the site of the skin on your stomach, upper arm, or thigh is clean and dry
  • Remove the cap from the pen and wipe the injection site with an alcohol swab
  • Choose a new needle. This helps prevent infections and any blocked needles
  • Push the capped needle straight into the pen and twist it until it is tight
  • Pull off the outer needle shield (cap) and keep it. You will reuse it later 
  • Hold the pen with firm pressure against the skin at a 90-degree angle. Then press the button to retract the needle
  • Once the needle is inserted into your skin, hold the pen still for 5 seconds, then release the button to retract (remove) the needle
  • Throw away the used pen, and put the needle in a sharps container or follow your doctor's instructions for safe disposal

Mounjaro needs to be taken weekly. It is important to take it at the same time every week. Avoid injecting the medication into the same spot (site) every time to prevent skin irritation. 

Mounjaro Dosages 

Multiple doses of Mounjaro are available, as treatment typically begins at a low dose and slowly increases over a few months. This process is called dose titration. How your doses increase depends on how your weight loss journey is progressing and how well you are tolerating the treatment. 

The starting dose for all new patients is 2.5mg of Mounjaro. Patient dosages typically follow: 

Month Dosage (per week)
12.5mg (starting dose)
25mg (maintenance dose)
410mg (maintenance dose)
615mg (maintenance dose)

It is important to remember that everyone's weight loss journey is different. Talk to your doctor or pharmacist about any side effects you experience, how well you are tolerating the dosage strength and any concerns about your weight loss that you may have.
