Discover how this dose fits into your treatment plan, what it costs and key information to help you stay on track.

What is Mounjaro 7.5mg?

Mounjaro (tirzepatide) is a once-weekly injectable medication that is used in weight loss management. The 7.5mg dose is the third step in the recommended dose escalation schedule.

The usual dosing schedule is:

  • Weeks 1-4: 2.5mg

  • Weeks 5-8: 5mg - maintenance dose

  • Weeks 9-12: 7.5mg

  • Weeks 13-16: 10mg - maintenance dose

  • Weeks 17-20: 12.5mg

  • Weeks 21-24: 15mg - maintenance dose

What does Mounjaro 7.5mg feel like compared to the lower doses?

Everyone responds differently to the medication but most will notice effects becoming more noticeable at 7.5mg.

You may experience:

  • Feeling fuller after smaller meals

  • Reduced appetite between meals

  • Less food cravings

  • Better portion control

Is weight loss faster at 7.5mg?

Some individuals may notice greater weight loss when they have increased to 7.5mg because the medication has a stronger effect on appetite and food intake. However, this does not mean that weight loss will be faster for everyone.

Weight loss depends on many factors, including:

  • Your starting weight

  • Diet and physical activity

  • Treatment consistency

  • Individual response to treatment

  • Other medical conditions

Sustainable, steady weight loss is much better than rapid weight loss.

Nausea

Nausea is the most common side effect. Here are some tips to help you reduce this side effect:

  • Eat smaller meals more frequently, rather than a few large meals

  • Avoid fatty and spicy food

  • Stay well hydrated

  • Eat slowly

  • Stop eating when you are satisfied with your meal

If nausea is severe, persistent, or prevents you from eating or drinking normally, contact your prescriber.

How long do side effects last?

Side effects are most noticeable during the first few days after a dose. These often improve after a few days, as the body adjusts to the medication.
If your side effects are severe or don’t seem to be getting any better, get in touch with your prescriber.

If you experience any severe abdominal pain, seek immediate medical attention.

Should I increase to 10mg?

The regular dosing schedule follows an increase in dose every 4-weeks. However, you do not have to increase your dose every month. Mounjaro has 3 maintenance doses: 5mg, 10mg, and 15mg - all of which can serve as a long-term dose.

You can also continue on your current dose if:

  • You are losing weight steadily

  • Your appetite is well controlled

  • You’re experiencing side effects that may need more time to settle.

If your 7.5mg dose is working for you and side effects are manageable, you can continue with it for more than 4-weeks.

What if Mounjaro 7.5mg is not working?

If you feel that Mounjaro 7.5mg is not producing the results you expected, don’t just stop your treatment.

You can always increase to the 10mg which may have the desired effect.

Get in touch with your prescriber if you’re unsure. This will give them the opportunity to review:

  • Your injection technique

  • Your dosing schedule

  • Your progress so far

  • Lifestyle factors such as diet and exercise

  • Whether it may be ideal for you to increase your dose

Remember that weight loss is often gradual, and progress is not always linear. You may have achieved non-scale victories as a result of your treatment - the number on the scales is not the only measure of progress.
