If you have plaque psoriasis, your doctor may recommend that you use Skyrizi.
Skyrizi is a prescription drug that’s used to treat moderate to severe plaque psoriasis in some adults. It’s prescribed for people who could use light therapy or systemic therapy for the condition. (Systemic therapy affects your whole body.)
With plaque psoriasis, you have thick red or dark-colored patches on your skin. To learn more about this condition and how Skyrizi is used to treat it, see the “What is Skyrizi used for?” section below.
Skyrizi comes as a solution inside prefilled syringes. You’ll take this drug by injecting it under your skin.
The active drug in Skyrizi is called risankizumab-rzaa.
Skyrizi is a biologic drug, which means it’s made from parts of living cells. It isn’t available in a biosimilar form. (Biosimilars are like generic drugs. But unlike generics, which are made for non-biologic drugs, biosimilars are made for biologic drugs.) Instead, risankizumab-rzaa comes only as the brand-name drug Skyrizi.
In this article, we describe how Skyrizi is taken, its side effects and uses, and more.
Your doctor will explain how you should take Skyrizi. They’ll also explain how much to take and how often. Be sure to follow your doctor’s instructions. Below are commonly used dosages, but always take the dosage your doctor prescribes.

Upper respiratory infection
You might get an upper respiratory infection (URI) while you’re taking Syrikiz. In fact, this was the most common side effect reported in studies of Skyrizi. Types of URIs include the common cold, sinus infections, and tonsillitis.
What might help
You can usually help relieve URI symptoms by taking over-the-counter drugs. A few suggestions are listed below:
- Antihistamines, which can help relieve sneezing and runny nose. Examples include loratadine (Claritin) and cetirizine (Zyrtec).
- Products that contain dextromethorphan, which can help reduce cough. An example of this kind of drug is Robitussin DM.
- Guaifenesin (Mucinex), which can help break up mucus in your chest.
- Decongestants, which can help relieve stuffy nose. Examples include oxymetazoline (Afrin) and pseudoephedrine (Sudafed).
Before taking any OTC medications, talk with your doctor or pharmacist. You can also try several home remedies that may ease URI symptoms.
If your URI symptoms aren’t improving, be sure to call your doctor.
The type of headache you have with Skyrizi can be different from person to person. Here are a few examples of different types of headaches you might have with this drug:
- tension headache, which can feel like a band around your forehead
- sinus headache, which can feel like pressure around your cheeks, forehead, eyes, or nose
- cervicogenic headache, a migraine-like headache causing pain at the bottom of your skull or in your neck
What might help
You can usually treat headache with OTC drugs, such as acetaminophen (Tylenol), ibuprofen (Advil), and naproxen (Aleve). It might also help if you apply a cold compress or heating pad to your head. Try doing this for 5 to 10 minutes several times throughout the day.
Ask your doctor or pharmacist before taking any medications with Skyrizi. And if your headache is severe, or it’s not getting better with these measures, be sure to call your doctor.
Pain, redness, or swelling at the injection site
After you get a Skyrizi injection, you may have pain, redness, or swelling at the site where the drug was injected. This side effect is called an injection site reaction. This was a common side effect in clinical studies of the drug.
What might help
You can try relieving symptoms of an injection-site reaction by applying a cold compress to the area affected. You can also try taking over-the-counter pain medications. These include acetaminophen (Tylenol), ibuprofen (Advil), and naproxen (Aleve). But check with your doctor or pharmacist before taking any medications with Skyrizi.
Avoid rubbing the injection site, as doing so can make your symptoms worse.
Some people may have an allergic reaction to Skyrizi. Symptoms of a mild allergic reaction can include:
- skin rash
- flushing (warmth, swelling, or redness in your skin)
A more severe allergic reaction is rare but possible. Symptoms of a severe allergic reaction can include swelling under your skin, typically in your eyelids, lips, hands, or feet. They can also include swelling of your tongue, mouth, or throat, which can cause trouble breathing.
Call your doctor right away if you have an allergic reaction to Skyrizi. But if you think you’re having a medical emergency, call 911 or your local emergency number.
If you have plaque psoriasis, your doctor may recommend Skyrizi treatment for you.
Skyrizi is prescribed to treat moderate to severe plaque psoriasis in some adults. It’s prescribed for people who could use light therapy or systemic therapy for the condition. (Systemic therapy affects your whole body.)
Plaque psoriasis is an autoimmune disorder. It causes thick, red or dark-colored patches of skin on the elbows, knees, lower back, and scalp. As an autoimmune disorder, plaque psoriasis is caused by your immune system attacking your own cells.
If you’re considering Skyrizi treatment, there are some important things you should discuss with your doctor. These include your overall health and any medical conditions you may have. These and other factors to consider before taking Skyrizi are described below.
Taking medications, vaccines, foods, and other things with a certain drug can affect how the drug works. These effects are called interactions.
Before taking Skyrizi, be sure to tell your doctor about all medications you take (including prescription and over-the-counter types). Also describe any vitamins, herbs, or supplements you use. Your doctor or pharmacist can tell you about any interactions these items may cause with Skyrizi.
Interactions with drugs or supplements

You shouldn’t receive live vaccines while you’re using Skyrizi. (Live vaccines are made from live forms of a virus.) Skyrizi can lower your ability to fight infections. So if you get a live vaccine, you may be more likely to get the infection the vaccine was meant to protect you from.
Before you get any vaccines while using Skyrizi, talk with your doctor or pharmacist.
Skyrizi may not be right for you if you have certain medical conditions or other factors that affect your health. Talk with your doctor about your health history before you take Skyrizi. Factors to consider include those in the list below.

Active infection or a history of reoccurring infections. You shouldn’t take Skyrizi if you have a current infection or if you’ve had reoccurring infections in the past. And be sure to tell your doctor right away if you get an infection while taking this drug.

How is Skyrizi different from other treatment options for plaque psoriasis?Anonymous patient
Skyrizi, like some other biologic drugs, is a systemic therapy. Systemic therapies are drugs that affect your entire body. With Skyrizi, the drug acts on your immune system to help reduce inflammation related to plaque psoriasis.
The other common type of treatment for plaque psoriasis is topical therapy. Topical therapies are applied directly to the site of inflammation or dryness. These drugs are typically corticosteroids that come as creams or ointments. Corticosteroids are drugs that lower the responsiveness of the body’s immune system.
