How is Siliq given?
Use Siliq exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Siliq is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
Siliq is usually given once a week for 3 weeks, and then once every 2 weeks thereafter. Follow your doctor's dosing instructions very carefully.
Read all instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Do not shake the medicine. Prepare your dose only when you are ready to give an injection. Do not use the medicine if it looks cloudy or has large particles in it. Call your pharmacist for new medicine.
Store prefilled syringes in their original container in the refrigerator. Protect from light and do not freeze.
Take the medicine out of the refrigerator and allow it to reach room temperature for 30 minutes before injecting your dose. Do heat the medicine in a microwave oven or place it into hot water. Leave the needle cap in place while the medicine warms to room temperature.
You may store a syringe for up to 14 days at room temperature. Keep the syringe in its original container and protect it from heat and light.
Any syringe warmed to room temperature should not be placed back into a refrigerator.
Each single-use prefilled syringe is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Brodalumab can lower blood cells that help your body fight infections. You may get an infection more easily. Call your doctor if you have signs of infection such as fever, chills, flu symptoms, diarrhea, painful urination, and skin warmth or redness.
It may take several weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after 12 weeks of using Siliq.
Siliq comes with a Medication Guide and a Patient Wallet Card that lists the symptoms of a serious side effect. Read this information carefully and carry the Wallet Card with you at all times so you will know what symptoms to watch for.
