Can You Inject Mounjaro in the Hip? (October 2026)

01 · Core answer

Which sites are licensed for Mounjaro?

Mounjaro is injected under the skin (subcutaneously) once a week, and only three areas are licensed: the stomach area, the front of the thigh, and the back of the upper arm if someone else gives the injection.¹ The hip is not on that list, so we do not recommend it.

02 · Next step

What should you do instead?

Choose the stomach or front of the thigh and move to a different spot each week. If you were drawn to the hip for the fat there, see our guide on injecting in love handles, or read where not to inject Mounjaro. If you have already used the hip once, do not panic: carry on with a licensed site next time and speak to your prescriber if you notice anything unusual.

New to the pen? You can start treatment through our Mounjaro pen consultation, and needles, a sharps bin and injection guidance come with every order.

03 · Rotating your site

Why rotating sites matters

The licensed guidance is to rotate the site with each dose.¹ A simple habit is to alternate between the left and right of the stomach, then the thighs. Staying within the licensed areas gives you plenty of room to vary the spot. For technique, see what angle to inject Mounjaro.

04 · Pen, timing and day

Timing and the pen

There is no best time of day: Mounjaro works the same morning or evening, with or without food. What matters is the same day each week.¹ Each KwikPen contains four weekly doses.¹ Prefer sitting? See injecting while sitting down.

05 · Hip pain and Mounjaro

If you have hip or injection-site symptoms

Tell your prescriber about any new or lasting symptom, and you can report suspected side effects through the MHRA Yellow Card scheme.¹⁹ Contact your clinical team if an injection-site reaction is spreading, hot, very painful, or lasts more than a week. Seek immediate medical help for severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); pain in the upper right abdomen, fever or yellowing of skin/eyes (possible gallbladder problems); or signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing.
