How many units is 5 mg of Tirzepatide at 5 mg/mL?

Draw

100units

1.00 mL on a U-100 insulin syringe

5 mg ÷ 5 mg/mL × 100 = 100 units

This dose exceeds 50 units (0.5 mL). Volumes greater than 0.5 mL may be uncomfortable for subcutaneous injection. Consult your provider about splitting the dose into two injections.

About the 5 mg Dose

The 5 mg dose is the first escalation step for both Mounjaro and Zepbound, used during weeks 5 through 8 of treatment. After completing four weeks at the 2.5 mg starting dose, patients double their dose to 5 mg. Some patients with type 2 diabetes may remain at 5 mg as a maintenance dose if they achieve adequate glycemic control with Mounjaro.

Frequently Asked Questions

In a 5 mg/mL vial, 5 mg tirzepatide equals 100 units. The calculation is (5 / 5) x 100 = 100 units. In a 10 mg/mL vial, it would be 50 units, and in a 25 mg/mL vial, it would be 20 units.

The 5 mg dose is used during weeks 5 through 8 of the Mounjaro and Zepbound titration schedules. It is the second dose level, following the 2.5 mg starting dose. After 4 weeks at 5 mg, patients typically escalate to 7.5 mg. However, some Mounjaro patients may stay at 5 mg if their diabetes is well-controlled.

The SURMOUNT-1 clinical trial showed that patients on 5 mg tirzepatide lost an average of 15% of their body weight at 72 weeks, which is a meaningful result. However, higher doses of 10 mg and 15 mg showed even greater weight loss of approximately 20% and 22.5% respectively. Your provider will determine if escalation beyond 5 mg is appropriate.

Some patients experience a temporary increase in gastrointestinal side effects when escalating from 2.5 mg to 5 mg, including nausea, decreased appetite, and occasional diarrhea. These effects typically subside within one to two weeks as your body adjusts. Eating smaller meals and staying hydrated can help manage these symptoms.
