The researchers call for a randomized DMT discontinuation trial in stable, older patients to help answer whether and when patients may stop DMT. Skip to main content. Conference Coverage. Neurology Reviews. However, Copaxone is called an immunomodulator, rather than an immunosuppressant. Biologics are drugs that are made from living cells.
Copaxone is made from chemicals. Examples of biologics used to treat MS include alemtuzumab Lemtrada , natalizumab Tysabri , and ocrelizumab Ocrevus. In general, you can keep taking it for as long as it continues to be safe and effective for you. In that case, your doctor will recommend an alternative treatment for you. Or you can contact the American Red Cross by visiting their website. When you get Copaxone from your pharmacy, your pharmacist will add an expiration date to the box of syringes and on the syringes themselves.
This date is typically 1 year from the date they dispensed the medication. The expiration date helps guarantee that the medication is effective to use during a certain period of time. If you have unused medication that has gone past the expiration date, talk to your pharmacist about whether you might still be able to use it. How long a medication remains good can depend on many factors, including how and where you store the medication. Instead, dispose of the syringe in a sharps container.
However, you can only store Copaxone at room temperature for up to 1 month. Doing this will protect the drug from light. This helps prevent others, including children and pets, from taking the drug by accident or harming themselves with the needle. You can buy a sharps container online, or ask your doctor, pharmacist, or health insurance company where to get one. This article provides several useful tips on medication disposal.
You can also ask your pharmacist for information on how to dispose of your medication. Some women have taken Copaxone during pregnancy. Animal studies have been done in pregnant females who were given Copaxone.
However, if you have certain side effects from Copaxone, such as flushing or nausea, drinking alcohol could worsen your side effects. After Copaxone was released onto the market, there were some reports of people using the drug having intolerance to alcohol.
With alcohol intolerance, you may have certain reactions right after consuming alcohol. These reactions could include flushing in your face or having a stuffy nose. If you drink alcohol, talk with your doctor about how much is safe for you to consume.
However, before taking Copaxone, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use. Sharing this information can help you avoid potential interactions. If you have questions about drug interactions that may affect you, ask your doctor or pharmacist. Copaxone is approved to treat relapsing forms of multiple sclerosis MS and clinically isolated syndrome CIS. MS is a long-term condition that gets worse over time.
It affects your central nervous system CNS , which is made up of your brain and spinal cord. Your CNS is also made up of nerves that send messages between your brain and the rest of your body. Each of these nerve fibers is surrounded by a protective layer of tissue called a myelin sheath. The myelin sheath is like the plastic coating that surrounds wires inside an electrical cable. With MS, your immune system starts mistakenly attacking myelin sheaths surrounding your nerves.
This causes inflammation that damages the myelin sheaths. The damage makes it harder for your nerves to send and receive messages. Depending on which nerves are damaged, your symptoms of MS can vary quite a bit. After your immune system attacks your myelin sheath, scar tissue can develop around the damaged areas. The scar tissue also makes it difficult for your nerves to send and receive messages. The areas of damage and scarring on your nerves are called lesions.
These periods are called remission. These periods are called relapses. Remission can also happen when your body makes new nerve pathways that bypass nerves that have been damaged by MS. Periods of remission can last from a few months up to a few years. Each episode of nerve damage and its resulting symptoms can last for a few days or a few months.
This is called an MS attack or MS relapse. Over time, the relapse symptoms may worsen or become more frequent. This worsening leads to difficulty in everyday tasks such as walking or speaking. Copaxone is called an immunomodulator. It works by changing the activity of certain cells in your immune system. These cells work in several ways to stop your immune system from attacking your myelin sheath tissue.
With fewer attacks to your myelin sheath, you should have fewer MS relapses. This is because the drug helps to prevent your condition from getting worse, rather than treating your current symptoms. But during treatment, your doctor may check to see if Copaxone is working for you. To do this, they may order certain imaging tests, such as an MRI scan. Before taking Copaxone, talk with your doctor about your health history.
Copaxone may not be right for you if you have certain medical conditions or other factors affecting your health.
These include:. Do not use more Copaxone than your doctor recommends. For some drugs, doing so may lead to unwanted side effects or overdose. You can also call the American Association of Poison Control Centers at or use their online tool. But if your symptoms are severe, call or go to the nearest emergency room right away.
Copaxone is a disease-modifying therapy that contains the active drug glatiramer acetate. It is an immunomodulating drug, although its mechanism of action is not fully understood. Glatiramer acetate is a synthetic protein molecule that is similar to one of the natural proteins found in myelin. It appears to activate T suppressor cells that suppress the immune response to myelin. Glatiramer thereby reduces the immune attack on myelin, resulting in both fewer MS relapses and slowed progression of the disease.
A significant amount of Copaxone is hydrolyzed in the subcutaneous tissue after administration. Both intact and hydrolyzed Copaxone enter the lymphatic and systemic circulation. The half-life of Copaxone is not known. Copaxone must not be used in people with a known allergy to either glatiramer acetate or mannitol. Keep the medication in the original packaging. Patients in the study were ages 40 and older, had experienced no relapses and reported stable disability progression measured by EDSS scores for at least 5 years, and had been taking medication for at least 3 years.
Once medications were ceased, patients were followed for at least three years. After discontinuing medication, 24 percent of patients experienced a clinician-reported relapse, 32 percent sustained three-month disability progression, and Researchers found 77 patients—or 42 percent—restarted medication after a median of 22 months.
Restarting medication was associated with a 59 percent risk reduction of disability progression. More than 2. Another way to know if the medication is not working is testing for neutralizing antibodies. As the name implies, these antibodies neutralize the medication, preventing it from working properly. Studies have demonstrated that up to 41 percent of patients develop persistent neutralizing antibodies on high dose interferon therapy within the first 12 to 24 months.
Other studies have questioned how important these antibodies are, and there is no clear consensus on testing for them. If you have high levels of neutralizing antibodies and no major relapses or MRI activity, your doctor may recommend that you be retested in three to six months.
If you have neutralizing antibodies to interferon and frequent relapses or excessive MRI activity, your doctor may recommend switching to another treatment not related to interferon. This is because sometimes you may benefit from a different concentration and formulation of the interferon. You may also change therapy from an interferon to glatiramer acetate or vice versa, or switch to natalizumab, mitroxantone, another chemotherapy, or possible combination of treatments.
It really depends on which treatment you and your doctor decide is best for you. You may decide to stop using MS treatments altogether. Please take into account that the natural history data suggest that of the 85 percent of the persons with relapsing remitting MS, 50 percent develop secondary progressive MS within 10 years and 90 percent within Delaying that progression until a better therapy option comes around may be the best option.
