Teplizumab-mzwv injection

pronounced as (tep liz' ue mab)

Why is this medication prescribed?

Teplizumab-mzwv injection is used to slow the progression of Stage 2 Type 1 Diabetes Mellitus (T1DM) to Stage 3 T1DM in adults and children age 8 years and older. Teplizumab-mzwv is in a class of medications called monoclonal antibodies. It works by partly blocking the immune system's attack on insulin-making cells in the pancreas.

How should this medicine be used?

Teplizumab-mzwv injection comes as a solution (liquid) to be given by a doctor or nurse intravenously (into the vein). It is given once a day for 14 days. Each teplizumab-mzwv infusion will take about 30 minutes. Your doctor will prescribe you several medicines to take in the days leading up to your first injection to reduce the chance of adverse effects happening.

Your doctor will order labs for you prior to starting teplizumab-mzwv injection to help determine if this medication will be safe for you. You will also be asked to be up to date on vaccines before starting teplizumab-mzwv therapy.

Teplizumab-mzwv injection slows the progression of T1DM but does not cure it. It is important that you finish your course of teplizumab-mzwv even if you feel well.
