1. What Tecfidera is and what it is used for

What Tecfidera is

Tecfidera is a medicine that contains the active substance dimethyl fumarate.

What Tecfidera is used for

Tecfidera is used to treat relapsing-remitting multiple sclerosis (MS) in adult patients.

MS is a long-term condition that affects the central nervous system (CNS), including the brain and the spinal cord. Relapsing-remitting MS is characterised by repeated attacks (relapses) of nervous system symptoms. Symptoms vary from patient to patient, but typically include walking difficulties, feeling off balance and visual difficulties (e.g. blurred or double vision). These symptoms may disappear completely when the relapse is over, but some problems may remain.

How Tecfidera works

Tecfidera seems to work by stopping the body’s defence system from damaging your brain and spinal cord. This may also help to delay future worsening of your MS.

2. What you need to know before you take Tecfidera

Do not take Tecfidera

• - if you are allergic to dimethyl fumarate or any of the other ingredients of this medicine (listed in section 6).

• - if you are suspected to suffer from a rare brain infection called progressive multifocal

leukoencephalo­pathy (PML) or if PML has been confirmed.

Warnings and precautions

Tecfidera may affect your white blood cell counts , your kidneys and liver. Before you start Tecfidera, your doctor will do a blood test to count the number of your white blood cells and will check that your kidneys and liver are working properly. Your doctor will test these periodically during treatment. If your number of white blood cells decreases during treatment, your doctor may consider additional analytic measures or discontinue your treatment.

Talk to your doctor before taking Tecfidera if you have:

• - severe kidney disease

• - severe liver disease

• - a disease of the stomach or bowel

• - a serious infection (such as pneumonia)

Herpes zoster (shingles) may occur with Tecfidera treatment. In some cases, serious complications have occurred. You should inform your doctor immediately if you suspect you have any symptoms of shingles.

If you believe your MS is getting worse (e.g. weakness or visual changes) or if you notice any new symptoms, talk to your doctor straight away because these may be the symptoms of a rare brain infection called progressive multifocal leukoencephalopathy (PML). PML is a serious condition that may lead to severe disability or death.

A rare but serious kidney disorder (Fanconi Syndrome) has been reported for a medicine containing dimethyl fumarate, in combination with other fumaric acid esters, used to treat psoriasis (a skin disease). If you notice you are passing more urine, are more thirsty and drinking more than normal, your muscles seem weaker, you break a bone, or just have aches and pains, talk to your doctor as soon as possible so that this can be investigated further.

Children and adolescents

Tecfidera is not recommended for use in children and adolescents because there is limited experience in the use of Tecfidera in this population.

Other medicines and Tecfidera

Tell your doctor or pharmacist if you are taking, have recently taken or might take any medicines, in particular:

• – medicines that contain fumaric acid esters (fumarates) used to treat psoriasis

• - medicines that affect the body’s immune system including other medicines used to treat

MS , such as fingolimod, natalizumab, teriflunomide, alemtuzumab, ocrelizumab or cladribine, or some commonly used cancer treatments (rituximab or mitoxantrone).

• - medicines that affect the kidneys including some antibiotics (used to treat infections), “water tablets ” (diuretics ), certain types of painkillers (such as ibuprofen and other similar antiinflammatories and medicines purchased without a doctor’s pres­cription) and medicines that contain lithium

• – Taking Tecfidera with certain types of vaccines (live vaccines ) may cause you to get an infection and should, therefore, be avoided. Your doctor will advise whether other types of vaccines (non-live vaccines) should be given.

Tecfidera with alcohol

Consumption of more than a small quantity (more than 50 ml) of strong alcoholic drinks (more than 30% alcohol by volume, e.g. spirits) should be avoided within an hour of taking Tecfidera, as alcohol can interact with this medicine. This could cause inflammation of the stomach (gastritis ), especially in people already prone to gastritis.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Do not use Tecfidera if you are pregnant unless you have discussed this with your doctor.

Breast-feeding

It is not known whether the active substance of Tecfidera passes into breast milk. Tecfidera should not be used during breast-feeding. Your doctor will help you decide whether you should stop breastfeeding, or stop using Tecfidera. This involves balancing the benefit of breast-feeding for your child, and the benefit of therapy for you.

Driving and using machines

The effect of Tecfidera on the ability to drive or use machines is not known. Tecfidera is not expected to affect your ability to drive and use machines.

3. How to take Tecfidera

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.

Starting dose

120 mg twice a day.

Take this starting dose for the first 7 days, then take the regular dose.

Regular dose

240 mg twice a day.

Tecfidera is for oral use

Swallow each capsule whole , with some water. Do not divide, crush, dissolve, suck or chew the capsule as this may increase some side effects.

Take Tecfidera with food – it may help to reduce some of the very common side effects (listed in section 4).

If you take more Tecfidera than you should

If you have taken too many capsules, talk to your doctor straight away. You may experience side effects similar to those described below in section 4.

If you forget to take Tecfidera

If you forget or miss a dose, do not take a double dose.

You may take the missed dose if you leave at least 4 hours between the doses. Otherwise wait until your next planned dose.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Serious effects

Tecfidera may lower lymphocyte counts (a type of white blood cell). Having a low white blood cell count can increase your risk of infection, including the risk of a rare brain infection called progressive multifocal leukoencephalopathy (PML). PML may lead to severe disability or death. PML has occurred after 1 to 5 years of treatment and so your physician should continue to monitor your white blood cells throughout your treatment, and you should remain observant of any potential symptoms of PML as described below. The risk of PML may be higher if you have previously taken a medicine impairing the functionality of your body’s immune system.

The symptoms of PML may be similar to an MS relapse. Symptoms may include new or worsening weakness on one side of the body; clumsiness; changes in vision, thinking, or memory; or confusion or personality changes, or speech and communication difficulties lasting for more than several days. Therefore, if you believe your MS is getting worse or if you notice any new symptoms while you are on Tecfidera treatment, it is very important that you speak to your doctor as soon as possible. Also speak with your partner or caregivers and inform them about your treatment. Symptoms might arise that you might not become aware of by yourself.

^ Call your doctor straight away if you experience any of these symptoms

Severe Allergic reactions

The frequency of severe allergic reactions cannot be estimated from the available data (not known).

Reddening of the face or body (flushing ) is a very common side effect. However, should flushing be accompanied by a red rash or hives and you get any of these symptoms:

• – swelling of the face, lips, mouth or tongue (angioedema)

• – wheezing, difficulty breathing or shortness of breath (dyspnoea, hypoxia)

• – dizziness or loss of consciousness (hypotension)

then this may represent a severe allergic reaction (anaphylaxis)

^ Stop taking Tecfidera and call a doctor straight away

• – reddening of the face or body feeling warm, hot, burning or itchy (flushing)

• – loose stools (diarrhoea)

• – stomach pain or stomach cramps

^ Taking your medicine with food can help to reduce the side effects above

Talk to your doctor about how to manage these side effects. Your doctor may reduce your dose. Do not reduce your dose unless your doctor tells you to.

Uncommon side effects
