Taspoglutide Dosing Calculator

Taspoglutide: once-weekly GLP-1 receptor agonist by Roche/Ipsen.

Pre-filled with the most-reported clinical reconstitution protocol for Taspoglutide. See how 1 mL and 2 mL of bacteriostatic water change concentration and syringe-draw volume, then adjust the calculator below for your own vial.

Quick answer · Clinical protocol

A 5 mg vial of Taspoglutide reconstituted with 2 mL of bacteriostatic water yields a concentration of 2.50 mg/mL. At that concentration, a 10 mg dose of Taspoglutide equals 400 units on a U-100 insulin syringe (4.000 mL). Taspoglutide is typically administered once weekly.

Taspoglutide reconstitution: 1 mL vs 2 mL bac water

Bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 5 mg vial.

Based on a 5 mg vial of Taspoglutide reconstituted with bacteriostatic water. Insulin-syringe units assume a standard U-100 syringe (100 units = 1 mL).

Alternative Taspoglutide protocols

Beyond the default above, Taspoglutide is also reported in the following protocols. Use these as starting points and recalculate with the tool above.

Type 2 Diabetes (T-emerge Phase 3 Protocol - High Dose)

Clinical
Dose
20 mg subcutaneous injection once weekly. The higher dose used across T-emerge trials.
Frequency
Once weekly subcutaneous injection
Duration
24-52 weeks in clinical trials

Never approved for clinical use. HbA1c reduction of -1.31% in T-emerge 2. Greater nausea and vomiting rates (59% nausea, 37% vomiting) compared to 10 mg dose.

Taspoglutide reconstitution & storage

Taspoglutide was supplied as a zinc-based depot suspension for subcutaneous injection. Specific reconstitution details were not widely published as the drug never reached market. The zinc formulation required careful preparation to ensure uniform suspension.

Clinical trial supplies were stored refrigerated at 2-8 degrees C. As taspoglutide never reached commercial availability, no official storage guidelines were published.

Taspoglutide dosing FAQ

How much bacteriostatic water should I add to a 5 mg vial of Taspoglutide?

The community standard is 2 mL of bacteriostatic water for a 5 mg Taspoglutide vial. That gives a concentration of 2.50 mg/mL, so a 10 mg dose is 400 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 5.00 mg/mL and halves the draw to 200 units. Less water = smaller injection volume but harder to measure precisely.

How many syringe units is a 10 mg dose of Taspoglutide?

On a standard U-100 insulin syringe, a 10 mg dose of Taspoglutide is 400 units when the 5 mg vial is reconstituted with 2 mL of bacteriostatic water (2.50 mg/mL). If you use 1 mL of bac water instead, draw 200 units (5.00 mg/mL).

What is the standard Taspoglutide dose?

Clinical protocols for Taspoglutide typically use 10 mg–2 mg once weekly via subcutaneous injection. 10 mg is a common starting dose. Never approved for clinical use. HbA1c reduction of -1.24% in T-emerge 2. Lower dose had somewhat fewer GI side effects than 20 mg.

Where do you inject Taspoglutide?

Taspoglutide is typically injected subcutaneously. Common sites reported in the literature and by users include: Abdomen, Thigh. Rotate sites with each injection to reduce localized irritation.

Can I use sterile water instead of bacteriostatic water for Taspoglutide?

Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like Taspoglutide because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
