2. What you need to know before you take Dimforda

Do not take Dimforda

• if you are allergic to dimethyl fumarateor any of the other ingredients of this medicine (listed in section 6).
• if you suspect that you have a rare brain infection calledprogressive multifocal leukoencephalopathy (PML) or if PML has been confirmed.

Warnings and precautions

Dimforda may affect your white blood cell count,kidneysand liver.Before starting Dimforda, your doctor will perform a blood test to check your white blood cell count and ensure that your kidneys and liver are working properly. Your doctor will perform regular blood tests during treatment. If you experience a decrease in white blood cell count during treatment, your doctor may consider additional tests or interrupt your treatment.

Consult your doctorbefore starting Dimforda if you have:

• severe kidney disease
• severe liver disease
• a stomach or intestinal disease
• a severe infection(e.g., pneumonia)

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

If you think that your MS is getting worse (e.g., weakness or changes in vision) or if you notice any new symptoms, talk to your doctor directly, as they could be symptoms of a rare brain infection called progressive multifocal leukoencephalopathy (PML). PML is a serious disease that can cause death or severe disability.

A rare but serious kidney disorder (Fanconi syndrome) has been reported with a medicine that contains dimethyl fumarate in combination with other fumaric acid esters, which is used to treat psoriasis (a skin disease). If you notice that you are urinating more, are thirstier, and drink more than usual, your muscles seem weaker, you break a bone, or simply have pains and discomfort, inform your doctor as soon as possible so that this can be investigated further.

Taking Dimforda with alcohol

After taking Dimforda, you should avoid consuming more than a small amount (more than 50 ml) of strong alcoholic beverages (with an alcohol content of more than 30%, such as spirits) for the first hour because alcohol may interact with this medicine.

4. Possible side effects

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

Serious side effects

Dimforda may decrease your lymphocyte count (a type of white blood cell). A low white blood cell count can increase the risk of infection, including a rare brain infection called progressive multifocal leukoencephalopathy (PML). PML can cause death or severe disability. PML has occurred after 1 to 5 years of treatment, so your doctor will continue to monitor your white blood cells during treatment, and you should remain alert to any possible symptoms of PML, as described below. The risk of PML may be higher if you have previously taken a medicine that has weakened your immune system.

The symptoms of PML can be similar to those of an MS relapse. The 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 difficulty speaking and communicating that may persist for more than several days. Therefore, it is very important that you talk to your doctor as soon as possible if you think that your MS is getting worse or if you notice any new symptoms while being treated with Dimforda. Also, inform your partner or caregivers about your treatment. It is possible that symptoms may arise that you are not aware of on your own.
