Glatiramer acetate is an injectable immunomodulator used to treat relapsing forms of multiple sclerosis (MS) in adults. This guide covers glatiramer acetate uses, how it works, dosage, side effects, precautions, drug interactions, use in pregnancy and breastfeeding, brand names and its approximate price in India.
What is Glatiramer Acetate?
Glatiramer acetate is an immunomodulator used to treat relapsing forms of multiple sclerosis (MS). It is approved for adults with a first attack that looks like MS (clinically isolated syndrome), relapsing-remitting MS, and active secondary progressive MS. In MS, the immune system attacks the protective cover of nerve fibers in the brain and spinal cord. This damage causes relapses. Glatiramer acetate helps lower how often relapses happen. It does not cure MS.
How Glatiramer Acetate Works
The exact mechanism of action in multiple sclerosis is not fully understood. Glatiramer acetate is thought to modify immune responses involved in MS. This is why it is called a disease-modifying therapy. It aims to reduce the immune attacks on the nerves, not to treat each symptom.
When Glatiramer Acetate Is Used
Multiple sclerosis: It is shown to reduce the number of relapses. Your neurologist decides if it suits your type of MS.
Glatiramer Acetate Dosage and How to Take It
The dosage details below are based on the U.S. prescribing information. Approved products and instructions can differ by country, so always follow the leaflet and advice for the product your doctor prescribes. Do not mix doses between different products.
- Adult dose: 20 mg injected under the skin once a day, or 40 mg injected three times a week, at least 48 hours apart. The two strengths are not interchangeable, so never switch between them on your own.
- Pediatric use: Safety and effectiveness have not been established in people under 18 years.
Your doctor chooses the strength and schedule for you. - How to inject: It is for injection under the skin only. Never inject it into a vein. The first injection should be given with a healthcare professional present, who will teach you the technique. Let the syringe warm to room temperature for about 20 minutes before use. The liquid should be clear and colorless to slightly yellow. Change the injection area each time. This lowers the risk of skin damage.
- Storage: Keep it in the refrigerator. If needed, it can stay at room temperature for up to one month. Do not freeze it.
Take this medicine only as advised by your doctor or healthcare professional. Do not start, stop, or change the dose on your own.
Side Effects of Glatiramer Acetate
Injection site reactions: These are the most common side effects. They include redness, pain, swelling, lumps and itching where the injection was given.
Other side effects seen in studies: Flushing, rash, shortness of breath and chest pain. Some of these can also be part of an immediate post-injection reaction, described below.
Serious side effects need medical care
- Immediate post-injection reaction: Within seconds to minutes after an injection, some people have flushing, chest pain, fast heartbeat, anxiety, breathing trouble, throat tightness or hives. These reactions can be short and settle on their own. But call your doctor if they happen. Do not take another injection until your doctor tells you to. Symptoms that are severe, get worse, do not go away, or look like a serious allergy need urgent medical care. This is because the signs can look the same as anaphylaxis.
- Anaphylaxis (severe allergy): It can be life-threatening. It can start after the first dose, or after months or even years of treatment. Most cases happened within an hour of an injection. Signs include widespread rash, swelling of the face, eyelids, lips, mouth, throat or tongue, sudden shortness of breath or wheezing, trouble swallowing or speaking, fainting or feeling dizzy, and uncontrolled shaking. Stop the medicine and get emergency help right away.
- Chest pain: Short episodes of chest pain can happen after an injection or on their own, usually starting a month or more after treatment begins. Do not assume chest pain is harmless. Tell your doctor about any chest pain. Get prompt medical help if the pain is severe, lasts long, keeps coming back, gets worse, or comes with breathlessness, sweating or fainting
- Skin damage: Fat under the skin can shrink at injection sites, leaving a dent that may be permanent. Skin death is rare. Rotating sites helps lower this risk.
- Liver problems: Liver injury, including liver failure, has been reported. It can happen days to years after starting. Tell your doctor promptly if you have yellow skin or eyes, dark urine, pale stools, loss of appetite, nausea or unusual tiredness. Your doctor may order liver tests when clinically appropriate.
Who Should Not Use Glatiramer Acetate, and Precautions
Do not use it if you are allergic to glatiramer acetate or mannitol. Anyone who has had anaphylaxis with this medicine should not use it again unless a clear other cause is found.
Glatiramer acetate can change immune responses, so it may affect how the immune system works. There is no evidence that it weakens the body’s defense against infections or tumors, but this has not been studied in a systematic way. Tell your doctor if you get frequent or serious infections.
Glatiramer Acetate in Pregnancy and Breastfeeding
Pregnancy: Available human data have not identified an increased risk of major birth defects or miscarriage, although the available studies have limits. So pregnancy cannot be called risk-free. Tell your doctor if you are pregnant or plan a pregnancy. Your doctor will weigh the benefits and risks with you.
Breastfeeding: There are no data on the medicine in breast milk. Very little reaches the blood, so the baby is not expected to get a meaningful amount. Your doctor will help you decide.
