Mounjaro 7.5mg Injection

Q1: What is Mounjaro 7.5mg used for?

Mounjaro 7.5mg is a dose escalation step in tirzepatide therapy, used for 4 weeks before advancing to 10mg. It delivers meaningful weight loss and glycaemic benefit and may serve as a maintenance dose for patients who meet their goals at this level.

Q2: Is 7.5mg considered a maintenance dose for Mounjaro?

For some patients, particularly those who achieve satisfactory weight loss and glycaemic control at 7.5mg, the prescriber may choose to maintain this dose rather than escalate further. The target dose is individualised.

Q3: How much weight loss is expected at Mounjaro 7.5mg?

In the SURMOUNT-1 trial, participants achieving steady-state tirzepatide doses in the 7.5–10mg range lost approximately 17–19% of body weight over 72 weeks with lifestyle intervention.

Q4: Can I take Mounjaro 7.5mg with insulin glargine?

Yes. Tirzepatide is studied in combination with basal insulin. When added to insulin, significant hypoglycaemia risk reduction is possible — many patients can reduce or eliminate insulin. Close blood glucose monitoring is essential.

Q5: Do the GI side effects get better at higher doses?

Side effects typically peak during dose escalation and improve as the body adapts. At 7.5mg, most patients who tolerated 5mg well experience only mild ongoing nausea that diminishes within 2–4 weeks.

Q6: Why is the Mounjaro escalation schedule slower than Wegovy?

Both programmes use 4-week escalation steps. Mounjaro uses increments of 2.5mg at each step, while Wegovy's increments vary. Both are designed to minimise GI adverse effects; neither should be rushed.

Q7: Can Mounjaro 7.5mg improve sleep apnoea?

Yes. Significant weight loss from Mounjaro substantially reduces severity of obstructive sleep apnoea. The SURMOUNT-OSA trial specifically demonstrated this benefit, with semaglutide-naïve patients showing dramatic reductions in apnoea-hypopnoea index scores.

Q8: What should I eat on Mounjaro 7.5mg?

A reduced-calorie diet rich in lean protein, vegetables, and fibre is recommended. Adequate protein (1.2–1.6 g/kg ideal body weight) is important to preserve lean muscle mass during rapid weight loss. Avoid large fatty meals that worsen nausea.

Q9: Can I stop Mounjaro 7.5mg if I feel I've lost enough weight?

Discuss any plans to stop with your prescriber. Weight typically returns after stopping. If you wish to discontinue, your prescriber may taper the dose rather than stopping abruptly, and will help you plan a maintenance strategy.

Q10: Is Mounjaro 7.5mg safe with cholesterol-lowering medications?

No clinically significant interactions are expected between tirzepatide and statins, ezetimibe, or fibrates. As weight loss progresses, lipid levels often improve and statin doses may be able to be reduced by your prescriber.
