Why is it important to keep my appointments with the doctor?

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • You may need to have routine blood tests (e.g. neutrophil and platelet count, liver function test, lipid profile) while you are being treated with Sarilumab. Your doctor will advise you about how often you will need to have these tests.
  • Your doctor may periodically conduct a test for TB and other infections while you are being treated with this medicine.
What side effects could I experience?
Sarilumab may cause any of the following side effects: cold sores, common cold, sore throat, upper airway infection, bladder infection, unusual bleeding or bruising, itching and redness at the site of injection.

Sarilumab will cause the level of your white blood cells and platelets to drop.

White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.

Platelets help your blood to clot when there is a cut in the skin. A fall in the level of your platelets may put you at risk of bleeding more than usual. Do not take part in activities where you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises, especially if the bruises appeared on their own) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).

Some side effects may need immediate medical help. Alert your doctor quickly if you experience fever, chills, or mouth sore. These could be signs of serious infection.

Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Can I use this with other medicines?
