Teva-Glatiramer Acetate: Uses, Side Effects and Dosage

What is TEVA-GLATIRAMER ACETATE used for?

TEVA-GLATIRAMER ACETATE 20 mg/mL (once-daily) is used to treat patients with Relapsing Remitting Multiple Sclerosis (RRMS), including those who have experienced one episode of nervous system symptoms and who have abnormalities on their brain scan that may be the first signs of Multiple Sclerosis.

TEVA-GLATIRAMER ACETATE 40 mg/mL (three times-a-week) is used to treat patients with Relapsing Remitting Multiple Sclerosis (RRMS).

TEVA-GLATIRAMER ACETATE is not a cure. Patients treated with TEVA-GLATIRAMER ACETATE experience fewer relapses (flare-ups of the disease).

How does TEVA-GLATIRAMER ACETATE work?

Multiple Sclerosis (MS) is thought to be a disease where your immune system causes your body to attack its own cells. This leads to loss of myelin, a substance that covers your nerve fibers. The loss of myelin eventually leads to the symptoms of MS.

TEVA-GLATIRAMER ACETATE is a mixture of small proteins. These small proteins are similar to a protein found in myelin. TEVA-GLATIRAMER ACETATE is thought to work by modifying the immune processes that are believed to cause MS.

What are the ingredients in TEVA-GLATIRAMER ACETATE?

Medicinal ingredients: Glatiramer acetate

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take TEVA-GLATIRAMER ACETATE. Talk about any health conditions or problems you may have, including if you:

Each pre-filled syringe should be:

• used only once.
• used only for subcutaneous injection.

• TEVA-GLATIRAMER ACETATE 20 mg/ mL pre-filled syringe is injected once a day.
• TEVA-GLATIRAMER ACETATE 40 mg/ mL pre-filled syringe is injected 3 times each week on the same 3 days each week, if possible (for example, Monday, Wednesday and Friday). The injections are given at least 48 hours (2 days) apart.

INSTRUCTIONS FOR USE FOR THE PRE-FILLED SYRINGE

Step 1: Gathering the materials

• With clean hands, collect one of each of the items you will need on a clean, flat surface in a well-lit area.

  • 1 TEVA-GLATIRAMER ACETATE pre-filled syringe. (Each syringe is contained inside a protective blister. Holding the package of syringes, tear off only 1 blister at a time. Keep all unused syringes in the refrigerator)

  • Alcohol swab (not supplied) or access to soap, water and a clean towel

  • Dry cotton ball (not supplied)
• Ensure that the solution is at room temperature. Let the unopened blister containing the syringe stand at room temperature for at least 20 minutes.
• Do not use if the medication is frozen. If TEVA-GLATIRAMER is frozen, or has ever been frozen, discard the product.
• Small air bubbles may be present in the liquid, which are harmless and can be injected. Do NOT try to force small air bubbles out of the syringe before injecting the medicine.

Step 2: Choosing the site for injection

You should have a planned schedule for your chosen injection sites and make note of it in a diary.

• There are 7 possible areas on your body for injection (see Figure 1):

  • back of upper arms (right and left)
  • front and outside of thighs (right and left)
  • upper buttocks/rear of hips (right and left)
  • stomach (abdomen)
• If you are taking TEVA-GLATIRAMER ACETATE 20 mg / mL (once-daily), pick a different area each day (one for each day of the week).
• If you are taking TEVA-GLATIRAMER ACETATE 40 mg /mL (three times-a-week), pick each injection area only once per week.
• Within each of the 7 areas there are many sites where you can inject the drug. Rotate the injection sites within the chosen area. Choose a different injection site each time.

Figure 1:

• Please note: do NOT inject in any area that is:

  • painful.
  • discoloured.
  • where you feel firm knots or lumps.
  • where skin depression has occurred (a “dent” at the injection site). Further injections in these sites may make the depression deeper.

Hard to inject areas: There may be some areas on your body that are hard for you to inject the drug yourself (such as the back of your arms). You should ask your healthcare professional for instructions on how to inject TEVA-GLATIRAMER ACETATE in these areas.

Step 3: Injection

1. 1. Before you inject wash and dry your hands. Avoid touching your hair or skin, after you have washed your hands. This will help prevent infection.
2. 2. Remove the syringe from its protective blister by peeling back the paper label. Place the syringe back on the clean, flat surface.
3. 3.

   Clean the site you have chosen to inject by using:

   1. • a fresh alcohol swab. (Let it air dry for 1 minute to reduce any stinging)
   2. • or
   3. • soap and water (dry with a clean towel)
4. 4. Using the hand you write with, pick up the syringe as you would a pencil. Remove the needle cap from the needle.
5. 5. With your other hand, pinch about a 5 centimeter (2 inch) fold of skin between your thumb and index finger (See Figure 2).
6. 6. While resting the heel of your hand against your body, insert the needle at a 90° angle. When the needle is all the way in the skin, let go the fold of skin (See Figure 3).

Figure 2 Figure 3

1. 7. To inject the medication, hold the syringe steady and push down on the plunger. This should take only a few seconds. (See Figure 3)
2. 8. Pull the needle straight out.
3. 9. Press a dry cotton ball on the injection site for few seconds.
4. 10. Throw out the syringe and the needle cap in a safe hard-walled plastic container.

Proper disposal of needles:

• Throw out all used syringes in a hard-walled plastic container (such as a Sharps container from a pharmacy).
• Keep the cover of this container closed tight and out of the reach and sight of children.
• When the container is full, check with your healthcare professional about proper disposal.
