As of April 2025, individuals relying on Mounjaro (tirzepatide) for weight management treatment in the UK are facing notable supply constraints, particularly concerning the higher-dose pens of 12.5mg and 15mg. These shortages have led to disruptions in treatment plans and raised concerns among patients and healthcare providers alike. Shortages expected to continue well into May 2025.
Understanding the Root Causes The scarcity of Mounjaro is primarily attributed to a surge in global demand for GLP-1 and GIP receptor agonists, a class of medications that includes Mounjaro, Ozempic, and Wegovy. This increased demand stems from the drugs' effectiveness in managing blood glucose levels and promoting weight loss.
Steps for Patients Amidst Shortages
- Proactive Communication: Reach out to your clinician ahead of your refill date, we suggest 2 weeks, to confirm the availability of your prescribed dose. Early communication can help in planning and avoiding treatment interruptions.
- Consult your Weight Medics Clinician: If your prescribed dose is unavailable, consult Weight Medics about possible alternatives. We may recommend adjusting the dosage or exploring other treatment options temporarily.
- Beware of Misinformation: Be cautious of unverified claims regarding Mounjaro availability. Some sources may disseminate misleading information for competitive advantage. Always rely on reputable weight loss clinic and providers and official health advisories for accurate updates.
- At Weight Medics, we prioritise transparency and reliability. We ensure that our patients are accurately informed about any Mounjaro stock shortages, expected delivery dates, and availability updates. We are committed to never knowingly prescribing a Mounjaro dose that isn’t currently in stock for immediate dispensing. Your health and confidence in our service matter to us, and we strive to provide clear communication and dependable care at every step.
Regulatory Measures and Patient Safety
In response to the growing demand and concerns over inappropriate prescribing practices, the UK's General Pharmaceutical Council (GPhC) has implemented stricter regulations for online pharmacies dispensing weight-loss medications like Mounjaro. These measures include mandatory verification of patient information beyond online questionnaires to ensure safe and appropriate use.
When Will Mounjaro Supply Improve?
Supplies of 12.5mg and 15mg pens are expected to remain limited into well into May 2025 with intermittent stock being received. Smaller doses (2.5mg, 5mg, 7.5mg, 10mg) are generally more available.
Looking Ahead
While supply challenges persist, efforts are underway to stabilize the availability of Mounjaro in the UK. Patients are encouraged to maintain open communication with their healthcare provider, stay informed through reliable sources, and adhere to prescribed treatment plans. By taking these proactive steps, individuals can navigate the current landscape effectively and continue their health journeys with confidence.
