Mounjaro 5mg Injection

Q1: What is Mounjaro 5mg used for?

Mounjaro 5mg is either the first maintenance dose or a titration step in tirzepatide therapy. It delivers meaningful clinical benefit for weight reduction in obesity and for HbA1c control in type 2 diabetes.

Q2: Can some patients maintain on 5mg long-term?

Yes. Some patients who achieve their weight and glycaemic goals at 5mg may be maintained at this dose indefinitely without needing higher doses. Your prescriber will determine the appropriate long-term dose.

Q3: How does Mounjaro 5mg compare to Ozempic 1mg?

In head-to-head SURPASS-2 trials, tirzepatide 5mg produced greater HbA1c reduction (–2.01% vs –1.86%) and weight loss (–7.6 kg vs –5.7 kg) compared to semaglutide 1mg after 40 weeks, demonstrating the superiority of the dual mechanism.

Q4: Does Mounjaro 5mg cause hair loss?

Hair loss (telogen effluvium) can occur with rapid weight loss on any agent including Mounjaro. It is typically temporary and resolves as weight loss stabilises. Adequate protein intake helps minimise this effect.

Q5: How do I know if my injection was successful?

After pressing the button, you should hear a click and see the plunger move in the window. The injection window (if present on your pen model) will change to confirm delivery. Hold the pen in place for 10 seconds before removing.

Q6: Can Mounjaro 5mg cause low blood sugar on its own?

Tirzepatide alone has a low risk of hypoglycaemia because insulin secretion is glucose-dependent. Risk increases when combined with insulin or sulphonylureas; dose reductions of those agents are often needed.

Q7: Is Mounjaro suitable for patients with PCOS?

Weight management is a cornerstone of PCOS treatment. By reducing weight and improving insulin sensitivity, Mounjaro may improve menstrual regularity and hormonal profiles in PCOS. This is an emerging area of use; discuss with an endocrinologist.

Q8: Can I travel internationally with Mounjaro pens?

Yes. Carry a doctor's letter describing the medication. Bring pens in their original packaging. Unused pens should be kept cool (2–8°C or in a cooler bag). In-use pens can travel at room temperature for up to 21 days.

Q9: What is the difference between Mounjaro and Zepbound?

Both contain tirzepatide. Mounjaro is branded for type 2 diabetes management, while Zepbound is the brand name specifically approved for chronic weight management in the US. The formulation and dosing are identical.

Q10: Does Mounjaro 5mg affect the liver?

Clinical data suggests tirzepatide may improve non-alcoholic fatty liver disease (NAFLD) by reducing hepatic steatosis. This is a potential added benefit for patients with obesity-related liver disease.
