Mounjaro may be suitable for adults who:
All patients must be assessed by a qualified healthcare professional before starting Mounjaro. This includes reviewing current medications, blood pressure, blood glucose, and overall health status.
Before using Mounjaro, speak to a healthcare professional if you:
Avoid alcohol and fatty meals while on treatment, as they may increase side effects like nausea and indigestion.
Mounjaro is injected once a week, on the same day each week.
Inject it subcutaneously in one of the following areas:
Change injection sites with each dose to reduce irritation in a specific area of the skin. Do not inject into muscles or veins. If you have missed a dose, take the next dose within 4 days, and if 4 days have passed, skip the missed dose.
Always follow the instructions provided during your consultation and on the packaging of the weight loss medication.
The active ingredient in Mounjaro is tirzepatide.
Tirzepatide is a synthetic peptide that activates both Glucose-Dependent Insulinotropic Polypeptide (GIP) and Glucagon-Like Peptide-1 (GLP-1) receptors. By engaging these receptors, tirzepatide:
Each pen delivers 2.5–15 mg of tirzepatide per dose as the dosage increases over time.
Adjusts tonicity, ensuring patient comfort upon injection
Used to adjust the pH of the formulation to approximately optimise peptide stability and solubility
Sterile, pyrogen-free water that serves as the primary solvent for the peptide and excipients
Includes phosphate buffer components (disodium hydrogen phosphate and sodium dihydrogen phosphate) to maintain pH stability, and polysorbate 20 to prevent peptide aggregation during storage and administration
Mounjaro pens are made to high-quality standards under GMP (Good Manufacturing Practice) conditions. Each batch is carefully tested to ensure over 95% purity, is sterile, contains very low levels of toxins, and is free from particles. The pre-filled pen is also checked to make sure it delivers the correct dose and is easy to use.
Mounjaro is made with ingredients that help reduce allergic reactions and keep the medicine stable. It has no added preservatives and is meant for one person only. After use, throw away the pen and needle in a sharps bin approved for medical waste.
Managing discomfort can be challenging, so here are some tips:
Inject at the same time each week for consistency
Staying hydrated is key if experiencing nausea, vomiting, or diarrhoea. Drink plenty of water and fluids
Eat smaller, more frequent meals throughout the day rather than larger meals. Increase fibre intake and fruits like prunes or figs to avoid constipation
Staying active maximises the benefits of weight loss and controls sugar levels, enhancing the effects of Mounjaro
Take your time while eating, as it helps with digestion and reduces feelings of excessive fullness
While rare, some side effects require prompt medical attention. It is crucial to be aware of the signs:
Persistent, severe pain in your stomach, with or without vomiting, could indicate acute pancreatitis
Swelling of the face, lips, or throat, difficulty breathing or swallowing, or a very rapid heartbeat
Sudden loss of vision or blurred vision that interferes with daily tasks, or seeing flashing lights or spots
Before starting Mounjaro, inform your healthcare provider if you have or have had:

Exceptional service. We needed medicine for my parents. The pharmacy was able to arrange stock and deliver the medication on the same day. The team really went the extra mile.
Really good staff! Very helpful and prompt. I had a really bad experience at my previous pharmacy, really happy I moved over. Recommend to everyone especially because they’re open 7 days a week even on bank holidays!
I had an excellent experience at Star Pharmacy! The staff is incredibly friendly, knowledgeable, and always willing to help. They go above and beyond to answer questions and ensure you get the right medication. The store is clean, well-organized, and fully stocked with everything you need. Highly recommend this pharmacy for their outstanding customer service!
Excellent pharmacy, quick and kind. Now that I’ve moved house, I still travel all the way here even though I could pick somewhere closer. Just couldn’t go anywhere else!
Always really helpful & so friendly. Even when not dispensing my medicine, the pharmacist has given me second opinion and checked me over. Have ordered me needles in that I had trouble getting elsewhere also. So refreshing to find a pharmacy who wants to help and is kind!
