Mounjaro Dosages

Each Mounjaro dose contains the active ingredient tirzepatide. There are 6 Mounjaro doses available:

• 2.5 mg
• 5 mg
• 7.5 mg
• 10 mg
• 12.5 mg
• 15 mg

Mounjaro comes in the form of an injectable pen, with pre-filled doses. This means you don’t need to draw up your dose before injecting it. You should take Mounjaro once weekly, at the same time and day. This makes the medication most effective and can reduce side effects by keeping the medication at a steady level.

Mounjaro can be injected into the upper legs or abdomen. It may also be injected into the upper arms but only with help from someone else. Switch your injection site each week to prevent soreness and irritation. You can find out more about injecting Mounjaro in the image below:

For more information on taking Mounjaro, read the patient information leaflet before taking it for the first time.

The Mounjaro dosing schedule is as follows:

The starting dose of Mounjaro is always 2.5 mg, even if you’ve taken weight loss injections before. You’ll usually stay at each dose for 4 weeks before increasing to the next Mounjaro dose.

You may need to stay on a lower dose for longer if you’re:

• getting severe side effects
• happy with your weight loss results at a dose of 5 mg or 10 mg

You can choose to increase your Mounjaro dose at any time, as long as it’s been longer than 4 weeks.

You can’t take more than 15 mg once a week as this is the maximum maintenance dose. Taking more than 15 mg could cause severe side effects and serious illness.

Mounjaro dosage chart

Our Mounjaro dosage chart explains when to increase your dose, but always follow your doctor’s instructions:

Mounjaro follows a dosing schedule to give your body time to adjust to the new medication. Increasing the dose too quickly, or starting at a higher dose, could increase your risk of side effects or serious illness. Mounjaro has been studied by doctors and the Mounjaro dosing schedule was created to be the safest and most effective way of taking Mounjaro. Other weight loss injections, such as Wegovy, also follow their own dosing schedule.

Wegovy works similarly to Mounjaro, is taken once weekly, and contains the active ingredient semaglutide. This is also the active ingredient in Ozempic, a type 2 diabetes treatment. The Wegovy dosing schedule is similar to Mounjaro’s as you increase your dose every 4 weeks, but there’s only one maintenance dose: 2.4 mg. You can find out more about the similarities and differences between Wegovy, Mounjaro, and Ozempic in our comparison guide.

According to a clinical study, the most effective Mounjaro dosage for weight loss is 15 mg, although lower doses are still effective. After 72 weeks of treatment, patients lost on average:

• 22.5% of their starting body weight while taking the 15 mg maximum maintenance dose
• 21.4% of their starting body weight while taking the 10 mg maintenance dose
• 16% of their starting body weight while taking the 5 mg maintenance dose

Mounjaro works best when following a diet and exercise plan. If you get Mounjaro prescribed from Asda Online Doctor, we’ll provide you with a weight loss support pack so you can get the most from your treatment.
