Glatiramer is part of a drug class known as immunomodulators. It slows down the worsening of MS by reducing the actions of immune cells that cause nerve damage. It also increases the time between relapses.
What Is Glatopa Used For?
Glatopa (glatiramer acetate) is a prescription drug used to reduce the number of relapses or set back with multiple sclerosis (MS).
How to Use Glatopa
The following steps outline how to use Glatopa:
Inject under the skin of your arms, hips, thighs, or stomach as directed by your healthcare provider. Wash your hands before and after use. Leave the syringe at room temperature for 20 minutes to warm up. Inspect the syringe. The liquid in the syringe should be clear and colorless. It may have a slight yellow tint to it. Do not use it if it is cloudy or has particles in it. Clean your injection site. Hold the syringe like a pencil. Remove the needle cover. Inject at a 90 degrees angle straight into your skin, slowly pushing down the plunger. Once injected, pull the needle straight out. Discard the needle correctly in a Food and Drug Administration (FDA)-cleared sharps disposal container. Gently dab a dry, clean cotton ball on the injection site for a few seconds.
Glatiramer is available in 20 milligrams per milliliter (mg/mL) and 40 milligrams per milliliter (mg/mL) injections. These strengths are not interchangeable. If injected three times a week, space it apart by at least 48 hours.
Rotate injection sites. Do not use the needle in the same spot more than once weekly.
Avoid getting live-attenuated vaccines if you are on this medicine or recently stopped using this injection, except if your healthcare provider tells you to.
Storage
Store Glatopa in the refrigerator and do not freeze. If it freezes, do not use it. Although refrigeration is preferred, you may store this drug at room temperature (68 to 77 degrees Fahrenheit or 20 to 25 degrees Celsius) for up to 30 days. Do not store in the bathroom. Throw away any unused medicine after 30 days.
Store this drug away from heat and intense light. Keep Glatopa away from children and pets.
Avoid pouring unused and expired drugs down the drain or in the toilet. Ask your pharmacist or healthcare provider about the best ways to dispose of this medicine.
