Mounjaro KwikPen is a once weekly injectable weight loss medication containing tirzepatide, a dual action GLP-1 and GIP receptor agonist. In December 2024, NICE recommended Mounjaro for weight management in the UK, and clinical trials have shown it produces some of the highest average weight loss results of any licensed medication.
At Newmans Pharmacy on Barking Road, Plaistow, we offer Mounjaro KwikPen through our pharmacist led private weight loss clinic, with face-to-face consultations, full eligibility checks and ongoing support.
The KwikPen is the multi-dose injector pen format of Mounjaro. Unlike single use pre-filled pens, the KwikPen contains multiple doses, which can be more convenient for ongoing maintenance treatment. It is designed for self-administration once weekly.

Mounjaro (Tirzepatide) is a dual-action medication that mimics two natural hormones in your body: GLP-1 and GIP. It works by slowing down digestion and signaling your brain to feel full for longer. This helps you reduce your calorie intake significantly. The KwikPen is a multi-dose, pre-filled device designed for easy once-a-week self-injection.
Mounjaro is a prescription-only medication (POM). At Newman’s Pharmacy, we offer a Weight Loss Clinic where our healthcare professionals can assess your eligibility. Generally, it is suitable for adults with a BMI of 30 or higher, or a BMI of 27 or higher if you have weight-related health conditions (like high blood pressure). Following a clinical consultation, we can provide the KwikPen and guide you on the correct titration (dosage increase) schedule.
