Proper Use of sarilumab
Sarilumab is given as a shot under your skin. Sarilumab may sometimes be given at home to patients who do not need to be in the hospital. If you or your child are using sarilumab at home, your doctor or nurse will teach you how to prepare and inject the medicine. Be sure that you understand exactly how to use sarilumab.
Sarilumab comes with a Medication Guide and patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions.
Sarilumab is available in 2 dosage forms: a prefilled syringe or aprefilled pen.
If you use sarilumab at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems.
Allow the medicine to warm to room temperature for 30 minutes (for the prefilled syringe) or 60 minutes (for the prefilled pen)before using it. Do not warm sarilumab in any other way.
Check the liquid in the prefilled syringe. It should be clear and colorless or slightly yellow. Do not use sarilumab if it is cloudy, discolored, if there are particles in it, or if the prefilled syringe is damaged or broken. Do not shake the medicine.
Do not inject into skin areas that are red, bruised, tender, hard, or have scars or stretch marks.
Do not remove the needle cap from the prefilled syringe or pen until you are ready to use it.
You might not use all of the medicine in each prefilled syringe or pen. Use each prefilled syringe and pen only one time. Do not save an open syringe or pen.
The dose of sarilumab will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of sarilumab. If your dose is different, do not change it unless your doctor tells you to do so.

Precautions While Using sarilumab
It is very important that your doctor check your progress at regular visits to make sure that sarilumab is working properly. Blood tests may be needed to check for unwanted effects.
Sarilumab injection will lower the number of some types of blood cells in your body. Because of this, you may bleed or get infections more easily. To help with these problems, avoid being near people who are sick or have infections. Wash your hands often. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers. Tell your doctor if you have any kind of infection before you start using sarilumab. Also tell your doctor if you have ever had an infection that would not go away or an infection that keeps coming back.
Call your doctor right away if you start to have a cough that will not go away, weight loss, night sweats, fever, chills, or flu-like symptoms, such as a runny or stuffy nose, headache, blurred vision, or feeling generally ill. These may be signs that you have an infection.
You will need to have a skin test for tuberculosis before you start using sarilumab. Tell your doctor if you or anyone in your home has ever had a positive reaction to a tuberculosis skin test.
Sarilumab may cause serious stomach and bowel problems, especially if you have a history of ulcers or diverticulitis (inflammation of the intestines). Check with your doctor right away if you start having severe stomach cramps or pain, black, tarry stools, diarrhea, fever, or vomiting that is severe and sometimes bloody while being treated with sarilumab.
Sarilumab may increase the amount of cholesterol and fats in your blood. If this condition occurs, your doctor may give you some medicines that can lower the amount of cholesterol and fats in the blood.
Sarilumab injection may increase your risk of having certain cancers. Talk to your doctor if you have unusual bleeding, bruising, or weakness, swollen lymph nodes in the neck, underarms, or groin, or unexplained weight loss. Also, check with your doctor right away if your skin has red, scaly patches, or raised bumps that are filled with pus.
Sarilumab may cause serious allergic reactions, including anaphylaxis. This can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after using sarilumab.
Do not have any live vaccines (immunizations) while you are being treated with sarilumab. Check with your doctor before having any vaccines.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
