Understanding BNF Guidelines for Mounjaro Treatment
What does the BNF say about Mounjaro classification?
The British National Formulary classifies Mounjaro (tirzepatide) as a prescription-only medicine for weight management in adults. According to BNF guidance, this weekly injectable treatment may be prescribed alongside reduced-calorie diet and increased physical activity following clinical assessment by a UK-licensed prescriber. The BNF emphasizes that Mounjaro is designed to support weight management as part of a comprehensive treatment approach, not as a standalone solution.

The formulary notes that treatment suitability must be assessed on an individual basis, with prescribers considering multiple clinical factors before determining appropriateness for each patient.
