Medication options
Mounjaro and Wegovy: what’s the difference?
Mounjaro and Wegovy are prescription-only treatments for medical weight loss. Your GP will discuss the available options and help decide which is suitable for you.
Wegovy
-
Active ingredient: Semaglutide
-
How it works: Wegovy is a GLP-1 receptor agonist. It acts on appetite and fullness signals, helping reduce hunger, food cravings and calorie intake.
-
Dose: Available as a daily tablet or a weekly injection. Your GP will explain the starting dose, gradual increases and how to take your prescribed treatment.
-
Evidence: In a major clinical trial, people taking Wegovy injections lost around 15% of their body weight on average over 68 weeks. Individual results vary.
-
Your GP will consider: Your weight, medical history, current medicines, diabetes or eye history, stomach or pancreas problems, pregnancy plans and side-effect risk.
Mounjaro
-
Active ingredient: Tirzepatide
-
How it works: Mounjaro is a dual GIP and GLP-1 receptor agonist. It acts on appetite, fullness and blood-sugar pathways, helping reduce hunger, cravings and calorie intake.
-
Dose: Treatment usually starts at 2.5mg once weekly and is increased gradually if tolerated.
-
Evidence: In a major clinical trial, people taking Mounjaro lost around 15–21% of their body weight on average over 72 weeks, depending on dose. Individual results vary.
-
Your GP will consider: Your weight, medical history, current medicines, diabetes treatment, stomach or pancreas problems, pregnancy plans and side-effect risk.
Treatment options
Daily tablets or weekly injections?
Both are prescription-only treatments. The right option depends on your health, current medicines, treatment history and which routine you are most likely to follow consistently. Tablets are not automatically safer, easier or more effective than injections. Switching must always be planned by a prescriber; do not overlap treatments or calculate a switching dose yourself.
Daily tablets
-
Available option: Wegovy tablets
-
How often: One tablet every day
-
How it is taken: Swallowed whole
-
Important routine: Take Wegovy tablets after fasting for at least eight hours, with no more than 120ml of water. Wait at least 30 minutes before eating, drinking or taking other oral medicines.
-
May suit: People who prefer to avoid injections and can consistently follow the daily fasting routine.
Weekly injections
-
Available options: Wegovy and Mounjaro
-
How often: One injection on the same day each week
-
How it is taken: Injected under the skin using a pre-filled pen
-
Important routine: There is no daily fasting routine, but you must be comfortable using and storing an injection pen.
-
May suit: People who prefer weekly treatment or who take several medicines in the morning.
