Do Pharmacies Inform My GP About Mounjaro? A Complete Guide
If you’re prescribed Mounjaro (tirzepatide) for weight loss or diabetes, you might wonder: Do Pharmacies Inform My GP About Mounjaro Prescriptions? The short answer is yes—but let’s explore why this happens, how it works, and what it means for your care.
Do Pharmacies Inform My GP About Mounjaro? The Rules Explained
Under the General Pharmaceutical Council (GPhC) guidelines (2025), pharmacies must notify your GP when supplying high-risk medications, including Mounjaro. This ensures your medical records stay up-to-date and helps prevent potential health risks.
Why Do Pharmacies Inform My GP About Mounjaro?
There are three key reasons why this rule exists:
- Safety First – Mounjaro can interact with other medications or affect ongoing treatments. If your GP doesn’t know you’re taking it, they might prescribe something unsafe.
- Continuity of Care – Your GP oversees your long-term health. If they’re unaware of your Mounjaro prescription, they might misinterpret symptoms or test results.
- Legal & Ethical Responsibility – Pharmacies must follow strict guidelines to protect patients. Failing to update your GP could lead to medication errors or missed warnings.
How Do Pharmacies Inform My GP About Mounjaro?
The process is simple and transparent:
- At Checkout, You Fill In Your GP Details
- Before ordering Mounjaro, the pharmacy should ask you to verify your GP surgery.
- This ensures the notification goes to the correct practice.
- A Secure Notification Is Sent
- Once your prescription is approved, the pharmacy sends a digital or letter-based update to your GP.
- This includes:
- The medication name (Mounjaro) and dosage
- The date of your consultation
- A note confirming a clinician reviewed your health history
- Your GP Updates Your Records
- The surgery adds this information to your file, so future treatments align with your current regimen.
Can I Opt Out?
For lower-risk medications, some pharmacies allow you to decline GP notifications. However, Mounjaro is classified as high-risk, meaning pharmacies must inform your GP by law.
Remember: This is about keeping you safe, not judging your preferences

What Happens If My GP Isn’t Informed About Mounjaro?
If your GP doesn’t know you’re taking Mounjaro, several risks arise:
- Dangerous Drug Interactions – Your doctor might prescribe something that clashes with tirzepatide.
- Incomplete Health Monitoring – Mounjaro can affect blood sugar, kidney function, and digestion. Without proper records, your GP might miss early warning signs.
- Delayed Adjustments – If you experience side effects, your GP may not realise they’re linked to Mounjaro.
Will My GP Stop My Prescription?
Most GPs won’t interfere if an online pharmacy prescribes Mounjaro legally and safely. However, they might:
- Contact you to discuss side effects or alternatives.
- Suggest follow-up tests (e.g., blood sugar checks).
- Update your records for future prescriptions.
How Long Does It Take for My GP to Be Notified?
Most pharmacies send updates within 24–48 hours of dispensing. However:
- Digital systems (like NHS GP links) can process notifications instantly.
- Paper letters may take 3–5 working days to arrive after being posted, however the whole process can be a lot longer, including review.
If you’re unsure, ask your pharmacy for confirmation.
What If My GP Disagrees with My Mounjaro Prescription?
In rare cases, your GP might have concerns. If so, they may:
- Discuss alternative treatments (e.g., Wegovy, Ozempic).
- Request further tests before continuing.
- Refer you to a specialist (e.g., an endocrinologist).
