What TECFIDERA is used for

TECFIDERA is used to treat relapsing multiple sclerosis (MS).
TECFIDERA slows down the progression of physical disability in people with relapsing forms of MS and decreases the number of flare ups (relapses).
Some people feel better when they start to take TECFIDERA. However TECFIDERA cannot repair damage that has already been caused by MS. When you start TECFIDERA you might not notice an improvement, but TECFIDERA may still be working to help prevent your MS from becoming worse.
The cause of MS is not yet known, MS affects the brain and spinal cord. In MS, the body's immune system reacts against its own myelin (the 'insulation' surrounding nerve fibres). In relapsing forms of MS, people have 'exacerbations' from time to time (e.g. blurred vision, weakness in the legs or arms, or loss of control of bowel or bladder function). They are followed by periods of recovery. Recovery may be complete or incomplete. If it is incomplete there is 'progression of disability'.
TECFIDERA contains the active ingredient dimethyl fumarate. Dimethyl fumarate decreases the inflammation in your brain that is caused by MS and thereby reduces nerve damage.
TECFIDERA works by reducing inflammatory responses in cells and helps to protect the central nervous system cells against attack. Inflammation of the brain is an important part of the MS disease process.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
TECFIDERA has not been studied in patients with chronic progressive MS.
This medicine is not addictive.
It is available only with a doctor's prescription.

How to take TECFIDERA

Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How much to take

The recommended starting dose of TECFIDERA is 120 mg given twice daily. After 7 days the recommended dose is 240 mg twice daily.

How to take it

Swallow each capsule whole with a glass of water. Do not crush, divide or dissolve the capsule or its contents.

When to take it

Take one capsule twice a day.
Taking it at the same time each day (e.g. at morning during breakfast and at night during dinner) will help you remember when to take it.
TECFIDERA can be taken with or without food. For those patients who experience gastrointestinal side effects or flushing, taking TECFIDERA with food may help reduce these effects.
Your doctor may tell you to take TECFIDERA with aspirin or may temporarily reduce your dose.
Do not reduce your dose unless your doctor tells you to.

How long to take it

Continue taking your medicine for as long as your doctor tells you.
This medicine helps to control your condition, but does not cure it. The positive effects of TECFIDERA may not be seen immediately. It is important to keep taking your medicine even if you feel well.
It is important not to interrupt treatment with TECFIDERA unless your doctor tells you to.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (in Australia telephone 13 11 26, in New Zealand telephone 0800 764 766) for advice, or go to Emergency at the nearest hospital, if you think that you or anyone else may have taken too much TECFIDERA. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.

While you are taking TECFIDERA

Things you must do

If you are about to have any blood or urine tests, tell your doctor that you are taking TECFIDERA.
TECFIDERA may decrease lymphocyte (white cell) counts that will show up in results of a full blood count.
Before you start TECFIDERA, your doctor will do a blood test to count the number of your white blood cells. Your doctor will test these periodically during treatment.
TECFIDERA may cause increases in the level of liver enzymes that will show up in a blood test.
TECFIDERA may cause proteins (albumin) to be detected in a urine test.
Take TECFIDERA exactly as your doctor has prescribed.
Tell your doctor as soon as possible if you notice any new or worsening medical conditions e.g., fever or infection.
Tell your doctor if you are going to be vaccinated.
Tell your partner or caregiver about your treatment.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking TECFIDERA.
Tell any other doctors, dentists, and pharmacists who treat you that you are taking this medicine.
If you become pregnant while taking this medicine, tell your doctor immediately.
Keep all of your doctor's appointments so that your progress can be checked.
Your doctor may do some blood and urine tests before and during your treatment.

Things you must not do

Do not take TECFIDERA to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.
Do not stop taking your medicine or lower the dosage without checking with your doctor.

Things to be careful of

Tell your doctor straight away if you think you have an infection, have fever, or feel like you have the flu.
TECFIDERA may decrease lymphocyte (white cell) counts. White blood cells fight infection. You may get infections more easily while you are taking TECFIDERA. Any infection that you already have may get worse. Infections could be serious and sometimes life-threatening.
Tell your doctor straight away if you think you are experiencing symptoms similar to an MS relapse, new or worsening weakness on one side of the body; clumsiness; changes in vision, thinking, or memory; or confusion or personality changes lasting for more than several days.
Having a low white blood cell count for a long period of time may increase your risk of a rare brain infection called progressive multifocal leukoencephalopathy (PML). The symptoms of PML may be similar to an MS relapse.
Your doctor will periodically do a blood test to count the number of your white blood cells while you are taking TECFIDERA.
