How Weight Loss Injections Are Supplied Through Pharmacies
Mounjaro and Wegovy are both prescription-only medicines, which means they can only be dispensed by a registered pharmacy against a valid prescription issued by an authorised prescriber. This applies whether you access them through a publicly funded healthcare programme (such as an NHS specialist weight-management service in the UK) or through a private prescribing route — the dispensing step always goes through a licensed pharmacy.
What to expect when collecting your pen
Pharmacies dispense these medicines as pre-filled injection pens. When you collect yours, the pharmacist or a member of their team should confirm your name, check the prescription details, and hand over the pen along with a patient information leaflet. If anything about the pack, the dose strength, or the instructions is unclear, ask the pharmacy team before you leave — they are there to help with dispensing questions.
Storage after collection
Injectable medicines like these generally require refrigerated storage until first use. Always read the patient information leaflet that comes with your pen, or check the electronic Medicines Compendium (eMC) entry for your specific medicine, for the exact storage requirements — figures can vary between products and it is important to follow the guidance for your particular pen.
Injection sites and rotation
Once you have your pen, injections are typically given into one of three areas: the abdomen, the front of the thigh, or the upper arm. Rotating between sites — rather than injecting into the same spot each time — is a commonly recommended practice to allow the skin and tissue at each site to recover. Your prescriber or doctor, and the instructions supplied with your medicine, are the right sources for guidance on technique. For a broader overview of injection considerations, see our guide to weight loss injections, or explore Mounjaro injection specifics in more detail.
If you have questions about whether your pharmacy can supply a particular dose strength, or whether your prescription covers a specific formulation, those are best directed to the dispensing pharmacy or your prescriber directly.

Tracking the right four numbers — weight, waist, protein and dose — turns a noisy chart into a clear story. That's the loop GLP-1 users keep coming back for.
AI Meal Tracking. Built for GLP 1 Appetites.
Point your camera at any meal and let our AI do the rest. Breakfast, doses, weight, mood all tracked in seconds.
Staying on Track After Every Pharmacy Collection
Collecting your pen is only the start — the consistency of your weekly injection schedule is what shapes your experience over time. That is where GLP Trackr is built to help.
Injection-site tracking and rotation reminders
GLP Trackr lets you log each injection as you give it: the date, the dose strength, and the site you used (abdomen, thigh, or upper arm). The app then tracks your rotation history and suggests your next site automatically, so you never have to rely on memory to avoid repeating the same spot. After a pharmacy collection, logging the new pen takes seconds and keeps your entire schedule in one place.
Dose reminders and missed-dose logging
Because Mounjaro and Wegovy are once-weekly injections, missing a dose is easier to do than it sounds — especially around busy weeks or a delayed pharmacy collection. GLP Trackr's dose reminders keep your weekly schedule visible, and if a dose is ever missed, you can log it in the app to discuss with your prescriber at your next appointment. Any decision about what to do after a missed dose belongs with your prescriber, not an app — but having a clear record to show them is genuinely useful.

If you ever experience a side effect that feels severe, persistent, or worrying after an injection, contact your healthcare professional promptly. GLP Trackr helps you record what you experience so you have an accurate account to share with them — it is not a substitute for their advice.
