How Mounjaro Is Prescribed and Dispensed
Because Mounjaro is a prescription-only medicine, a qualified healthcare professional — such as a doctor or specialist prescriber — must assess your suitability before it can be issued. That assessment considers your medical history, current medicines, and whether this treatment is appropriate for you. Suitability is always an individual clinical decision.
The role of your prescriber
Your prescriber determines your starting dose, monitors your progress over time, and decides whether your dose should be adjusted. This is not something to manage independently — any changes to your regimen should always happen in conversation with the person who prescribed it. For a fuller look at how Mounjaro works and what the treatment involves, see our complete Mounjaro guide.
Collecting your prescription from a pharmacy
Once a prescription has been issued, Mounjaro is dispensed by a registered pharmacy. In some healthcare systems a doctor's practice may work closely with a specific pharmacy, while in others you may take a prescription to any registered dispenser. Your prescriber or the pharmacy team can advise on the process in your area. It is worth noting that Mounjaro comes as a pre-filled injection pen and must be stored correctly — check the patient information leaflet that came with your pen for storage guidance, as conditions such as refrigeration requirements are product-specific.
A note on "extracting" medicine from the pen
Occasionally people search for information about how to extract Mounjaro from the pen. The device is a single-use pre-filled pen designed to deliver one dose as intended — it is not meant to be disassembled or used in any other way. If you have questions about how to use your pen correctly, your prescriber, pharmacist, or the patient information leaflet are the right sources of guidance. You may also find it useful to read about what the process of getting Mounjaro from a doctor involves in more detail.
Mounjaro is not currently available as a tablet — it is an injectable medicine only. For context on what forms it comes in, see our page on Mounjaro tablets.

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 Once You Have Your Prescription
Having a prescription is the beginning of the journey, not the end — and consistency matters. One of the most practical things you can do once you start Mounjaro is keep a clear record of every dose: when you took it, which strength, and where you injected. That record becomes genuinely useful when you speak to your prescriber at follow-up appointments.
GLP Trackr is built specifically for this. The app's dose logging feature lets you record each injection — date, time, and dose strength — so nothing gets lost or forgotten across a weekly schedule. Pair that with the injection-site rotation tracker, which logs where you injected and suggests your next site, making rotation automatic rather than something to mentally keep track of. If you ever want to share a clear summary of how your treatment has been going, the app's doctor report pulls your logged data into a format you can bring to a prescriber appointment.
GLP Trackr is a tracking companion — it is not a medical service and does not offer clinical advice. All decisions about your prescription, your dose, and your treatment plan belong with your prescriber or doctor, who knows your full history. If anything about your treatment concerns you, contact your healthcare professional directly.
