Copaxone (glatiramer acetate) is a prescription medication indicated for the management of symptoms associated with multiple sclerosis (MS). This medication is administered as an injection beneath the skin (subcutaneous injection) and is believed to work by stimulating healthy immune cell production, thereby reducing nerve damage caused by MS. Discuss Copaxone MS treatment side effects with your doctor before you begin using this medication.
Injection Site Reaction
The most common side effect associated with Copaxone treatment in patients with MS is injection site reaction. In clinical trials for this medication, the U.S. Food and Drug Administration (FDA) reports that at least 40 percent of Copaxone-treated patients experienced redness or pain at the site of injection. Additional injection site reaction symptoms can include itching, inflammation or swelling. Some patients can also develop a temporary lump at the injection site. To limit the severity of such reactions, the injection location should be rotated with each dose.
Stomach Upset
Stomach-related side effects can include nausea, vomiting, stomach pain or diarrhea. If you experience any of these symptoms after Copaxone treatment, you may also notice a decrease in your appetite. These symptoms can lead to body weight alterations in some patients.
Flu-like Symptoms
You can develop symptoms of fever, sore throat, chills, fatigue, headache or body aches, which can be uncomfortable. Certain patients can also experience pain within specific body regions--such as the joints, neck, stomach, ears or back--say health professionals at Drugs, a peer-reviewed drug information website. Fever caused by Copaxone treatment can lead to excess sweating or flushing (redness) of the skin.
Breathing Difficulties
When using Copaxone, you can develop a sensation of tightness or pressure within your chest, which can make it difficult for you to inhale normally. The FDA reports that 14 percent of Copaxone-treated patients experienced breathing difficulties (dyspnea) during clinical trials, while only 4 percent of placebo-treated patients reported similar side effects. Contact your doctor immediately if you experience chest pain or discomfort during treatment. Such side effects can be indicative of a more severe medical problem.
Swelling
While receiving treatment with Copaxone, you can develop abnormal swelling within your facial tissues or extremities. You may notice that your legs or feet appear enlarged or puffy, which can cause discomfort when you walk and move about normally. If you develop swelling of the mouth, lips or tongue, seek emergency medical care. These symptoms may be caused by an allergic reaction to this medication.
