Considerations to communicate to your doctor
Copaxone may be impacted by other medications; as well as affect the way other medications work. Your doctor will be able to tell you if any medications you are currently taking fall into these categories, or if they might impact your treatment with Copaxone. Pregnant or nursing mothers should discuss the use of Copaxone, as it is not known if the medication will impact a developing fetus, or if Copaxone is excreted through breast milk.
Administering Copaxone injections
Copaxone comes in a blister pack with prefilled syringes. Visually inspect each syringe for particulate matter and discoloration prior to use. The solution should appear clear, colorless to slightly yellow. If particulate matter (things floating around) or discoloration is observed, discard the syringe.
A healthcare professional should train patients or caregivers in the proper technique for administering subcutaneous injections. Typical injection sites are the abdomen, back of the upper arm, and thigh. Sites should be rotated to minimize the chance of injection site reactions. Injections should not be administered where the skin is bruised, irritated or red, infected, or scarred. Safe disposal practices should be used for needles and syringes.
Copaxone is the brand name for the compound glatiramer acetate. In recent years the FDA has approved two generic version of the medication. Glatiramer acetate injection is the therapeutic equivalent to Copaxone. The generic is comparable to the original in dosage, strength, and route of administration, quality, effectiveness, and intended use.
