Mounjaro and Metformin Combination

Many patients successfully use Mounjaro alongside metformin treatment. During your clinical assessment, our prescribers will review your current metformin dosage and medical history to ensure safe combination therapy. This dual approach may help optimise your treatment outcomes when used alongside reduced-calorie diet and increased physical activity.

Why Choose Single Pens?

Single pens offer flexibility for patients transitioning from metformin monotherapy or wanting to trial specific doses. Perfect if you're working with your healthcare provider to find the right tirzepatide dose while maintaining your current metformin regimen. Each single pen provides one month of treatment with four weekly injections.

Quick Clinical Assessment Process

Our streamlined consultation covers your metformin treatment, diabetes management history, and suitability for combination therapy. Standard approval takes 3 working days, or upgrade to express 24-hour service for faster access to treatment. All assessments conducted by UK-registered prescribers familiar with diabetes combination therapies.
