GAMMAGARD LIQUID is the only IVIG in clinical trials shown to improve grip strength and reduce disability in MMN*

GAMMAGARD LIQUID is an antibody therapy that contains immunoglobulin G (IgG). The term Ig means antibodies, like the ones you have in your immune system to fight infections. However, with MMN, your body's immune system may mistakenly attack your motor nerves. Ig therapy infuses a specific type of antibody into your body to support a healthy immune system. Your doctor might also refer to GAMMAGARD LIQUID as an Ig treatment, intravenous Ig or IVIG.

*In a 60-week clinical study with 44 adults with MMN, GAMMAGARD LIQUID was shown to improve or maintain grip strength and reduce disability compared to placebo.

GAMMAGARD LIQUID is made from plasma donations

GAMMAGARD LIQUID is supported by a strong legacy of more than 60 years of experience in IgG therapies. IgG is derived from plasma, which is part of human blood. Every step of the process used to make GAMMAGARD LIQUID ensures that your therapy is reliable and meets high safety standards.

3 steps to meet high safety standards

The plasma that’s used to make GAMMAGARD LIQUID goes through a rigorous process to get rid of viruses that could have potentially been included during the collection.

STEP 1. Virus reduction

Plasma cells inactivating the viruses.

The plasma is treated with a solution that inactivates viruses within minutes

STEP 2. Virus removal

Plasma cells removing viruses.

The plasma goes through a filter process to remove small germs by size

STEP 3. Virus inactivation

Plasma in a temperature safe container.

The plasma is kept in special conditions to further inactivate viruses

Why are plasma donors needed?

They can save lives. For many rare diseases, including MMN, immunoglobulin is an important treatment available—and it can’t be made without plasma donations. Learn more and find a donor center near you.


If a BioLife Center is not in your area, you can also donate through the American Red Cross.
