1. What is Dimethyl Fumarate Tecnigen and what is it used for

What is Dimethyl Fumarate Tecnigen

Dimethyl Fumarate Tecnigen is a medicine that contains dimethyl fumarateas the active substance.

What Dimethyl Fumarate Tecnigen is used for

Dimethyl Fumarate Tecnigen is used to treat relapsing-remitting multiple sclerosis (MS) in patients aged 13 years and over.

MS is a long-term disease that affects the central nervous system (CNS), which includes the brain and spinal cord. Relapsing-remitting MS is characterized by repeated attacks (relapses) of neurological symptoms. The symptoms vary from person to person but often include: difficulties with walking, balance problems, and vision problems (e.g., blurred or double vision). These symptoms can disappear completely when the relapse is over, but some problems may remain.

How Dimethyl Fumarate Tecnigen works

Dimethyl Fumarate seems to work by preventing the body's defense system from damaging the brain and spinal cord. This may also help to delay future disability in MS.

2. What you need to know before you take Dimethyl Fumarate Tecnigen

N

• If you are allergic to dimethyl fumarateor any of the other ingredients of this medicine (listed in section 6).

-i you suspect that you have a rare brain infection called progressive multifocal leukoencephalopathy (PML) or if PML has been confirmed

Warnings and precautions

Dimethyl Fumarate Tecnigen may affect your white blood cell count, kidneys, and liver. Before starting Dimethyl Fumarate Tecnigen, your doctor will do a blood test to get a white blood cell count and check that your kidneys and liver are working properly. Your doctor will do regular blood tests during treatment. If you have a low white blood cell count during treatment, your doctor may consider additional tests or stop your treatment.

Consult your doctorbefore starting Dimethyl Fumarate Tecnigen if you have:

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

Herpes zoster (shingles) may occur during treatment with Dimethyl Fumarate Tecnigen. In some cases, serious complications have occurred. You must inform your doctor immediatelyif you suspect you have any symptoms of shingles.

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

A rare but serious kidney disorder called Fanconi syndrome has been reported with a medicine containing 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 aches and pains, inform your doctor as soon as possible so that this can be investigated further.

Children and adolescents

Do not give this medicine to children under 10 years old because there is no data available for this age group.

• medicines that affect the body's immune system, including chemotherapy, immunosuppressants, or other medicines used to treat MS;
• medicines that affect the kidneys, includingsome antibiotics(used to treat infections), diuretics(pills that increase urine production), certain types of painkillers(such as ibuprofen or similar anti-inflammatory medicines, and over-the-counter medicines), and medicines containing lithium;
• the use of Dimethyl Fumarate Tecnigen and the administration of certain types of vaccines (live vaccines) could cause you to get an infection, and therefore, should be avoided. Your doctor will tell you if you should receive other types of vaccines (inactivated vaccines).

After taking dimethyl fumarate, 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

Dimethyl Fumarate 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 greater if you have previously taken a medicine that has made your immune system weaker.

The symptoms of PML can be similar to those of an MS relapse. The symptoms can 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 your MS is getting worse or if you notice any new symptoms while being treated with dimethyl fumarate. 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.
