Wegovy and Mounjaro are two popular injectable weight loss treatments that work by regulating appetite and supporting reduced calorie intake. As their use has grown in the UK, many patients want to understand the differences between them and whether one may be better suited to fasting during Ramadan.
Regulated access to both treatments is available at The Care Pharmacy, supported by professional assessment and ongoing guidance. This comparison covers how Wegovy and Mounjaro function, their side effect profiles, and important points to consider during fasting. Contact us to explore your options, or start an online consultation form to review your suitability.
Wegovy contains semaglutide and works by mimicking a hormone involved in appetite control. It helps you feel full sooner and reduces hunger signals. Mounjaro contains tirzepatide and works on two hormone pathways linked to appetite and blood sugar regulation.
Both are taken once weekly using an injection pen. Both aim to support gradual, sustainable weight loss when combined with healthy lifestyle habits.

Both Wegovy and Mounjaro can cause digestive side effects, particularly during the early weeks or after dose increases. Common symptoms include nausea, diarrhoea, reduced appetite, and mild fatigue.
Symptoms often improve for many patients once the body gets used to the treatment. Smaller meals, lower fat food choices, and consistent hydration can help reduce discomfort.
Side effects may feel more noticeable during fasting if calorie intake drops significantly. Professional review before Ramadan is recommended.
Ramadan fasting involves abstaining from food and drink from dawn to sunset. Both Wegovy and Mounjaro are once weekly injections and do not contain calories, so the injection itself does not break the fast.
However, fasting changes hydration levels, meal timing, and blood sugar balance. As both treatments reduce appetite and slow digestion, some patients may experience stronger side effects during fasting.
Start an online consultation form to review your treatment plan and ensure safe continuation during Ramadan.
There is no single answer that applies to everyone. Some patients find Wegovy easier to tolerate during fasting, while others feel comfortable continuing Mounjaro. The decision often depends on previous side effects, current dose, and individual health factors.
Patients who are stable on their current dose and not experiencing significant side effects are often able to continue treatment with careful hydration and balanced evening meals.
A professional review is particularly important if you have diabetes or any other medical conditions.
