What is Mounjaro?
Mounjaro is the brand name for tirzepatide. It is a prescription treatment approved in the UK for people with type 2 diabetes. People who are overweight or with obesity can also get this treatment to lose weight because it can be prescribed off-label. And should be taken under your doctor’s supervision.
By helping your body use insulin more effectively, Mounjaro supports better blood sugar control. It can reduce your appetite by helping you to feel fuller for longer. When you combine your Mounjaro with healthy eating and lifestyle changes, it can support your steady and meaningful weight loss.
How Mounjaro Works
Mounjaro is given as a once-a-week injection under the skin. One reason it’s okay to take it at different times of the day is because it stays in your body for several days.
Mounjaro builds up steady levels in your body over time, unlike daily medicines that work in short bursts. That’s why doctors focus on taking it once every week, rather than at a specific time of the day.
Best Time of Day to Take Mounjaro
If you are new to Mounjaro and still have no idea what is the best time of the day to take it, what we can say is that: there is no “best” time for that.
According to medical experts, it doesn’t matter if you take your Mounjaro on morning, afternoon, or evening because it does not change its effectiveness. What really matters is that you inject it on the same day each week.
In practice, the best time of the day is the time that you will not forget to inject.
