What Is Copaxone?
Copaxone is a brand-name prescription medication of glatiramer acetate, which is used to treat multiple sclerosis (MS) and prevent further relapses of the condition. The medication is made up of amino acids and combines them in order to affect the immune system in order to prevent it from attacking the nerves in MS. Although Copaxone is not effective in completely curing multiple sclerosis, it can minimize the incidences of relapses.
Who Manufactures Copaxone?
Copaxone is manufactured by Teva Pharmaceuticals, an Israeli pharmaceutical company headquartered in Tel Aviv. The company’s specialty is in generic versions of brand-name drugs, an industry in which it is the largest company in the world, competing primarily with Pfizer. Teva Pharmaceuticals does also have its own proprietary medications as well, including Copaxone.
Who Is Teva Pharmaceuticals?
The company was founded in its earliest form as a wholesale drug company in Jerusalem in 1901. At that period in history, Jerusalem was still located within the Ottoman Empire rather than within the independent country of Israel. By the 1930s and 1940s, the company began to take on its present form after the founders grew the company with loans from immigrants to the area. In the 1950s, the company went public before later merging with Assia and Zori, acquiring its current name, Teva Pharmaceuticals, Ltd. at that time.
Is Copaxone FDA-Approved?
The medication is currently approved by the FDA for patients who are diagnosed with MS. The purpose of the medication is to reduce the occurrence of relapses of MS. The drug is also approved for use with individuals who have gone through an initial clinical episode for clinically isolated syndrome and have MRI results consistent with an MS diagnosis.
What Is Multiple Sclerosis?
Multiple sclerosis (MS) is a brain and nervous system disease in which the body’s immune system attacks the myelin sheath that coats the nerve fibers. This results in communication problems between the body and the brain. MS can, over time, cause the nerve fibers to deteriorate and can cause permanent damage to the body’s nervous system.
Is There a Cure for Multiple Sclerosis?
There is no cure for MS. However, medications like Copaxone can help to manage symptoms, aid in recovery after an attack, and modify the disease’s course.
What Are the Symptoms of Multiple Sclerosis?
The symptoms of MS can include:
- Lack of coordination
- An unsteady gait
- Inability to walk
- Vertigo
- Numbness in one or more limbs on one side of the body
- Weakness in one or more limbs on one side of the body
- A tingling feeling
- Certain neck movements cause electric shock sensations
- Double vision (prolonged)
- Partial loss of vision in one eye at a time
- Complete loss of vision in one eye at a time
- Pain during eye movement
- Blurred vision
- Slurred speech
- Fatigue
- Cognitive problems
- Mood problems
- Sexual function problems
- Bladder function problems
- Bowel function problems
Which symptoms someone experiences can vary. One person’s experience of multiple sclerosis can be very different from someone else’s. The symptoms may also change over the course of the disease depending on which nerves in the body are impacted.
What Are the Types of MS?
Multiple sclerosis typically progresses as a cycle of remission and relapse. Each relapse may result in different symptoms that can develop over a period of days or weeks. Relapses are then followed by periods of remission in which symptoms either partially improve or go away completely. Remission periods can last for months or even up to years before symptoms start to return. In some people, MS is just a cycle of relapses and remissions while in others, the symptoms gradually get worse.
What Is Clinically Isolated Syndrome (CIS)?
In CIS, you can develop some of the symptoms of multiple sclerosis for a period of a minimum of 24 hours. In some, CIS can eventually develop into MS.
What Is Relapsing-Remitting Multiple Sclerosis (RRMS)?
RRMS is the type of multiple sclerosis in which you experience a cycle of relapses and remissions. There are periods in which the MS symptoms flare up and then other periods in which the symptoms either improve or go away altogether.
What Is Secondary Progressive Multiple Sclerosis (SPMS)?
SPMS is a type of multiple sclerosis in which symptoms steadily get worse over time. There still may be cycles of relapse and remission with SPMS, but here, the relapse periods involve symptoms that are worse than usual and symptoms persist through remission periods but just aren’t as severe during those times.
What Causes Multiple Sclerosis?
In those who are suffering from multiple sclerosis, their immune systems attack the myelin sheath that coats the endings of nerves in the spinal cord and the brain. The myelin sheath functions similarly to the plastic insulation on the exterior of an electrical wire. If that exterior coating is damaged, it can interfere with the proper functioning of the wires. Similarly, if the myelin sheath on nerves is damaged, the messages those nerves transmit can be slowed or even blocked.
What causes the immune system to start attacking the myelin sheaths in the body’s nervous system is still unknown, however. It’s thought that a combination of genetic and environmental factors may be at play.
What Are the Risk Factors of Multiple Sclerosis?
The following are risk factors that can increase your chances of developing multiple sclerosis:
- Genetics
- Family history
- Smoking
- Climate (cooler climates)
- Low vitamin D levels
- Gender/sex (women)
- Age (20-40)
- Race (white)
- Obesity
- Certain autoimmune disorders
- Certain infections
What Complications Can Occur from Multiple Sclerosis?
Multiple sclerosis can result in the following complications:
- Muscle spasms
- Muscle stiffness
- Severe weakness, especially in the legs
- Paralysis, especially in the legs
- Bladder problems
- Bowel problems
- Sexual dysfunction
- Forgetfulness
- Cognitive difficulties
- Depression
- Anxiety
- Mood swings
- Rare seizures
How Does Copaxone Work?
Copaxone is delivered as an injection under the skin. Some individuals may have a more serious reaction than others. Make sure you inform your doctor about whether or not you are allergic to Mannitol or Glatiramer prior to taking Copaxone. You should also inform your doctor if you plan to become pregnant or are currently pregnant.
Glatiramer is a synthetic protein used for treating MS and works by simulating myelin’s basic proteins that insulate the spinal cord and nerve fibers in the brain. Although the mechanism for doing so is not entirely understood at this time, the drug works by blocking T-cells that damage myelin.
What Are the Side Effects of Copaxone?
The side effects of taking Copaxone can range from common to severe. Bear in mind that other medications may also interact with Copaxone including vitamins, over-the-counter medicines, herbal products, and prescription drugs, causing some side effects. You should always talk to your doctor if you have concerns about medications interfering with one another prior to taking a new one.

Why Is Teva Pharmaceuticals Facing Copaxone Lawsuits?
Teva Pharmaceuticals is facing Copaxone lawsuits from both the United States government and insurance companies over accusations of the company receiving kickbacks and using shady marketing practices in order to sell more Copaxone.
What Copaxone Lawsuits Are There?
In 2013, former sales reps for Teva sued the company as whistleblowers, claiming that the company was paying doctors kickbacks to prescribe Copaxone and Azilect at so-called “educational” events that weren’t actually educational but were instead shams set up to facilitate sales of the drugs.
In 2020, the United States government filed a complaint against Teva Pharmaceuticals USA, citing the False Claims Act. This complaint alleged that Teva had paid kickbacks to boost its Copaxone sales through charitable organizations. This, according to the lawsuit, resulted in the submission of false claims to Medicare.
In 2022, Blue Cross and Blue Shield of Vermont and the Vermont Health Plan filed a lawsuit against Teva Pharmaceuticals alleging that the company used overly aggressive marketing tactics in order to sell more Copaxone. The plaintiffs claimed that Teva issued coupons to consumers that would encourage them to buy Copaxone instead of a cheaper generic alternative. During this period, from 2002 to 2019, Teva made more than $30 billion from sales of Copaxone. The insurance companies sued because while individuals benefited from the discounted price of Copaxone, those companies ended up paying the difference between the generic version of the drug and the price Teva was charging for the brand name Copaxone.
Teva Pharmaceuticals faces another 2022 lawsuit, this time from the country of Israel, which claims that the company has failed to pay $100 million in royalties. Teva owned the rights to market Copaxone, but the drug itself was developed by scientists at the Weizmann Institute of Science and therefore were owed royalties from Teva’s sales of the drug.
What Is the False Claims Act?
The False Claims Act is a federal law that holds any person or organization that defrauds a US government program liable for that fraud. This act, also called the Lincoln Act, is the government’s primary legal means for combating any fraud perpetrated against it. In the case of Teva, the False Claims Act complaint was that Medicare had been defrauded through false claims.
What Is a Kickback?
A kickback is a type of bribery in which a person or an organization receives a commission for a service that has been rendered. Teva has been accused of paying kickbacks through charities in order to bribe a boose in sales for Copaxone.
What Copaxone Lawsuit Settlements Are There?
In 2020, Teva Pharmaceuticals paid a $54 million settlement in a lawsuit claiming that the company had paid kickbacks in order to boost Copaxone sales. Other cases are still ongoing regarding Teva’s alleged kickbacks, aggressive marketing, and violations of the False Claims Act.
Notwithstanding claims relating to this product, the drug/medical device remains approved by the U.S. FDA.
