1. What Skilarence is and what it is used for

What Skilarence is

Skilarence is a medicine that contains the active substance dimethyl fumarate. Dimethyl fumarate acts on cells of the immune system (the body's natural defenses), modifying their activity by reducing the production of certain substances involved in the development of psoriasis.

What Skilarence is used for

Skilarence tablets are used to treat moderate to severe plaque psoriasis in adults. Psoriasis is a condition that causes certain areas of the skin to thicken, become inflamed, or turn red, often covered with whitish scales.

In general, response to Skilarence can be seen as early as week 3 and improves over time. Experience with related medicines containing dimethyl fumarate has shown that the beneficial effects of treatment last for at least 24 months.

2. What you need to know before taking Skilarence

Do not take Skilarence

• if you are allergic to dimethyl fumarate or any of the other ingredients of this medicine (listed in section 6)
• if you have severe stomach or intestinal problems
• if you have severe liver or kidney problems
• if you are pregnant or breastfeeding

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Skilarence.

Monitoring

Skilarence may cause problems with your blood, liver, or kidneys. You will have blood and urine tests before starting treatment and then periodically during treatment. These tests are performed to ensure you are not experiencing these complications and to confirm you can continue taking this medicine. Depending on the results of these blood and urine tests, your doctor may decide to increase the dose of Skilarence according to the recommended schedule (see section 3), maintain the current dose, reduce the dose, or stop treatment completely.

Infections

White blood cells help your body fight infections. Skilarence may reduce the number of white blood cells. Talk to your doctor if you think you have an infection. Symptoms include fever, pain, muscle aches, headache, loss of appetite, and general weakness. If you develop a serious infection before or during treatment with Skilarence, your doctor may advise you to stop taking Skilarence until the infection has resolved.

Gastrointestinal disorders

Inform your doctor if you have or have had stomach or intestinal problems. Your doctor will advise you on any precautions to take during treatment with Skilarence.

Children and adolescents

Children and adolescents under 18 years of age should not take this medicine, as it has not been studied in this age group.

Other medicines and Skilarence

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

In particular, inform your doctor if you are taking the following:

• Dimethyl fumarate or other fumarates: the active substance in Skilarence, dimethyl fumarate, is also used in other medicines, such as tablets, ointments, and bath preparations. You should avoid using other products containing fumarates to prevent overdose.
• Other medicines for psoriasis, such as methotrexate, retinoids, psoralens, cyclosporine, or other medicines that affect the immune system (such as immunosuppressants or cytostatics). Taking these medicines together with Skilarence may increase the risk of adverse effects on your immune system.
• Other medicines that may affect kidney function, such as methotrexate or cyclosporine (for psoriasis), aminoglycosides (for infections), diuretics (to increase urination), non-steroidal anti-inflammatory drugs (for pain relief), or lithium (used for bipolar disorder and depression). Taking these medicines together with Skilarence may increase the risk of adverse effects on your kidneys.

If you experience severe or prolonged diarrhoea due to Skilarence, other medicines may not work as effectively. If you have severe diarrhoea, consult your doctor. If you are taking an oral contraceptive (the pill), this is especially important, as its effectiveness may be reduced and you may need to use additional contraceptive methods to prevent pregnancy. Please refer to the instructions in the contraceptive's package leaflet.

If you need to be vaccinated, consult your doctor. Certain types of vaccines (attenuated vaccines) may cause an infection if used during treatment with Skilarence. Your doctor can advise you on the best course of action.

Taking Skilarence with alcohol

Do not consume strong alcoholic drinks (more than 50 ml of spirits containing over 30% alcohol by volume) during treatment with Skilarence, as alcohol may interact with this medicine. This interaction between alcohol and the medicine could cause stomach and intestinal problems.

Pregnancy and breastfeeding

Do not take Skilarence if you are pregnant or planning to become pregnant, as Skilarence may harm the unborn baby. Use effective contraception to avoid pregnancy during treatment with Skilarence (see also “Other medicines and Skilarence” above).

If you have stomach or intestinal problems that could reduce the effectiveness of oral contraceptives, consult your doctor, who will advise you on alternative contraceptive methods.

You must not breastfeed during treatment with Skilarence.

Driving and using machines

Skilarence has a minor influence on the ability to drive and use machines. You may feel dizzy or tired after taking Skilarence. If affected, take care when driving or operating machinery.

Skilarence contains lactose

If your doctor has informed you of an intolerance to certain sugars, consult with them before taking this medicine.

Skilarence contains sodium

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; this is essentially “sodium-free”.

3. How to take Skilarence

Follow exactly the instructions for use of this medicine given by your doctor or pharmacist. If in doubt, please consult your doctor or pharmacist again.

Dosage

Your doctor will start treatment with a low dose of Skilarence using 30 mg tablets. This helps your body adapt to the medicine and reduces the risk of side effects, such as stomach and intestinal problems. The dose will be increased weekly by an additional 30 mg, as indicated in the following table. Once the dose of Skilarence 120 mg per day is reached, usually from week 4 onwards, you may switch to 120 mg tablets for convenience. When switching from the 30 mg to the 120 mg dose, make sure that the tablet and dose you are taking are correct.

Your doctor will monitor how your condition improves after you start taking Skilarence and whether you experience any adverse effects. If you experience severe adverse effects after your dose has been increased, your doctor may recommend that you temporarily return to the previous dose. If the adverse effects are not very bothersome, the dose will be gradually increased until your disease is well controlled. You may not need the maximum dose of 720 mg per day as indicated in the table above. Once your condition has improved sufficiently, your doctor will consider gradually reducing your daily dose of Skilarence to the lowest dose required to maintain improvement.

Instructions for use

Skilarence tablets must be swallowed whole with liquid. Take the tablet(s) during a meal or immediately after a meal. Do not crush, split, dissolve, or chew the tablets, as they have a special coating that helps prevent stomach irritation.

If you take more Skilarence than you should

If you think you have taken too many Skilarence tablets, contact your doctor or pharmacist.

If you forget to take Skilarence

Do not take a double dose to make up for missed doses. Take the next dose at the usual time and continue taking the medicine exactly as described in this leaflet or as agreed with your doctor. If in doubt, consult your doctor or pharmacist.

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