What is SILIQ ?
SILIQ is a psoriasis injection (biologic) for adults with plaque psoriasis who have tried other systemic treatments (oral or injection). It works inside your body — with your body’s chemistry — to block the processes that are causing psoriasis. Learn more about SILIQ.
How do I take SILIQ ?
SILIQ is a medicine that you inject in your skin. Your first 3 doses will be injected 1 week apart. After that, you will inject SILIQ every other week. Remember that SILIQ works best when taken regularly on time. Get more information on injecting SILIQ.
How does SILIQ work?
SILIQ works differently than other psoriasis injections (biologics). SILIQ is targeted, which means that it only works against the proteins involved in psoriasis. Some other targeted psoriasis injections (biologics) work against 1 protein involved in psoriasis. SILIQ blocks 4 proteins that are involved in psoriasis. Watch a video on how SILIQ works.
How long does it take for SILIQ to work?
In medical studies, most patients (87%) saw half or more of their plaque psoriasis go away in the first month of treatment. Some patients (10%) became totally clear in the first month. Many patients (69%) eventually became totally clear with more time. See how long it took SILIQ to work in patients like you.
How long do SILIQ results last?
Every patient is different. In medical studies, 68% of patients were totally clear at the end of the first year and 69% were totally clear at the end of the second year. On average, patients saw about 95% clearance by the end of the third month and that remained consistent for nearly 4 years when the study ended. See more data on how long results with SILIQ last.
What should I do if I miss a dose?
Please talk to your doctor if you miss a dose. Learn more about using SILIQ.
How is SILIQ stored?

SILIQ should be stored in the refrigerator. If you forget to put SILIQ in the refrigerator, it can stay at room temperature for up to 14 days before using it. However, if you leave it out at room temperature, you cannot put it back in the refrigerator.

Store SILIQ in its original box to keep it protected from light or damage. Learn more about how to store SILIQ.

What should I do if my syringe is damaged?
If you drop your syringe, it becomes frozen, or the needle cap is missing, use a different syringe and call 1-800-321-4576 to ask about additional replacement doses.
Can I travel with SILIQ?
Yes. You should keep SILIQ cold in a cooler bag with cold packs while you are traveling. Be sure to request a refrigerator for your hotel room. Learn more about how to store SILIQ.
How do I dispose of the needles and syringes?
You should dispose of your injection materials in a needle disposal container. Your pharmacy will provide instructions on how to dispose of the filled container and how to get a new one. Learn more about disposing SILIQ materials.
