What is Glatiramer Acetate?

Glatiramer acetate is a mixture of synthetic polypeptides composed of four amino acids (glutamic acid, lysine, alanine, tyrosine) in a specific molar ratio. It is FDA-approved for relapsing forms of multiple sclerosis. It works by shifting the immune response from pro-inflammatory Th1 to anti-inflammatory Th2, reducing MS relapses by approximately 30%.

Moderate

How It Works

Glatiramer acetate looks like the myelin coating on nerves that the immune system mistakenly attacks in MS. It acts as a decoy, redirecting the immune attack and shifting immune cells from harmful to protective mode.

Common Questions

Safety Information

Important Safety Notes

Common Side Effects

Injection site reactions (very common)Post-injection systemic reaction (flushing, chest tightness, anxiety — transient)Lipoatrophy at injection sites

Cautions

  • Injection site rotation is important
  • Post-injection reaction can be alarming but is self-limiting
  • Not for progressive MS

What We Don't Know

Well-characterized safety profile with over 25 years of clinical use. One of the safest MS therapies available.
