When a new pharmacy assesses you, give the exact product and strength on your prescription, your real dose history and any symptoms. Do not work out your next dose from an old pack. Your prescriber decides the next step after reviewing your history. ## What Mounjaro (tirzepatide) is Mounjaro contains tirzepatide. The NHS describes tirzepatide as a prescription medicine for type 2 diabetes and obesity. Tirzepatide acts on GIP and GLP-1 pathways and comes as an injection. Diabetes care and weight-loss care may run under different arrangements. Tell a new pharmacy why you were prescribed Mounjaro. Keep the patient leaflet from your own pack. Start there for how to store and inject your product. ## Records to gather before you change Mounjaro pharmacy Write down these details before your consultation: - the exact product name and printed strength - the date you started your current strength - the date of your last dose - the dates of your recent orders Photograph the dispensing label (the pharmacy sticker on your box). If the label and an order page show different details, ask your current pharmacy to clear up the difference. Tell the new pharmacy if you also take diabetes medicines, if other treatment has changed or if you have had a pause. A new weight-loss service may not see records held by your GP or another provider. If you switch pharmacy every month (https://pharmacyhopper.co.uk/guides/switch-pharmacy-every-month/) to pay a new-customer price, have these details ready each time. ## Questions to ask at your Mounjaro consultation - Is staying on my current treatment right for me once you have reviewed my history? - What do you need to check my recent orders and use? - Who do I contact if the new order is delayed? - What check-ins or follow-up do you recommend? - Can you confirm the plan in writing, with the next treatment date? ## How to handle your Mounjaro pen Follow the leaflet and training supplied with your pen. Do not draw out extra medicine, follow click-counting instructions from forums or share pens. If you are unsure whether a pen was stored correctly or works, ask the dispensing pharmacy before you use the pen. This page gives no schedule for stepping up your dose and no restart advice. Those decisions need your health history. ## Mounjaro dose changes and missed doses Read going up, staying the same or reducing a Mounjaro dose (https://pharmacyhopper.co.uk/guides/increase-stay-reduce-dose/) for the questions to ask your prescriber. If you have missed treatment, use the missed-dose and longer-break guide (https://pharmacyhopper.co.uk/guides/treatment-gaps/) to build an accurate timeline. ## Frequently asked questions What medicine is in Mounjaro?
