Understanding Skyrizi (Risankizumab-rzaa): Uses, Dosage, and Side Effects

What is Skyrizi?

Skyrizi, with the active ingredient risankizumab-rzaa, is a prescription medication designed to manage certain inflammatory conditions. It works by targeting specific proteins in your immune system, thereby reducing the inflammation that triggers symptoms associated with conditions like plaque psoriasis, psoriatic arthritis, Crohn's disease, and ulcerative colitis. It's important to understand that Skyrizi is not a cure, but rather a treatment to help control these chronic conditions.

In India, access to advanced biologic therapies like Skyrizi is becoming more common, offering new hope for patients with severe autoimmune diseases. Your doctor plays a vital role in determining if Skyrizi is the right choice for you, considering your overall health and the severity of your condition.

Who Can Benefit from Skyrizi?

Skyrizi is generally prescribed for individuals who have not responded adequately to other treatments or have moderate to severe forms of the following conditions:

• Plaque Psoriasis: This is a chronic skin condition characterized by red, itchy, scaly patches, often on the knees, elbows, scalp, and trunk. Skyrizi helps to clear these skin lesions.
• Psoriatic Arthritis: A type of arthritis that affects some people who have psoriasis. It can cause pain, stiffness, and swelling in the joints.
• Crohn's Disease: A chronic inflammatory bowel disease that can affect any part of the gastrointestinal tract, leading to abdominal pain, diarrhea, fatigue, and weight loss.
• Ulcerative Colitis: Another inflammatory bowel disease that causes long-lasting inflammation and sores in your digestive tract, primarily affecting the colon and rectum. Symptoms include diarrhea, abdominal pain, and rectal bleeding.

How Does Skyrizi Work?

Skyrizi targets a protein called interleukin-23 (IL-23). IL-23 plays a significant role in the inflammatory processes that drive conditions like psoriasis and inflammatory bowel diseases. By blocking IL-23, Skyrizi helps to reduce the inflammation in your skin, joints, or gut, leading to symptom relief.

Understanding Skyrizi Dosage and Administration

The way Skyrizi is administered and the dosage schedule depend heavily on the condition being treated and your individual response. It's crucial to follow your doctor's specific instructions precisely.

Dosage for Plaque Psoriasis and Psoriatic Arthritis:

For these conditions, Skyrizi is typically given as an injection under the skin (subcutaneous injection). The initial treatment often involves:

1. Starter Doses: You'll usually receive two starter doses of 150 mg each, given 4 weeks apart.
2. Maintenance Doses: After the starter doses, you'll likely transition to a maintenance dose of 150 mg given once every 12 weeks.

Dosage for Crohn's Disease and Ulcerative Colitis:

Treatment for inflammatory bowel diseases often begins with intravenous (IV) infusions, followed by injections.

1. Induction Phase (IV Infusions): You will receive three starter doses of 600 mg each via IV infusion. These are typically given at weeks 0, 4, and 8 of treatment. This phase helps to quickly reduce inflammation in the gut.
2. Maintenance Phase (Injections): Starting at week 12, you will switch to subcutaneous injections. The maintenance dose is usually 180 mg or 360 mg, administered every 8 weeks. Your doctor will determine the most effective dose for you.

Important Administration Notes:

• IV Infusions: These are administered by a healthcare professional in a clinic or hospital setting and usually take at least an hour.
• Subcutaneous Injections: For maintenance therapy, your doctor may train you or a caregiver on how to administer these injections at home, offering greater convenience.

Potential Side Effects of Skyrizi

Like all medications, Skyrizi can cause side effects. It's important to discuss these with your doctor before starting treatment. Most side effects are mild to moderate, but some can be serious.

Common Side Effects:

• Upper respiratory infections (like the common cold)
• Headaches
• Fatigue
• Nausea
• Diarrhea
• Injection site reactions (redness, itching, or swelling where the injection was given)

Serious Side Effects:

While less common, serious side effects can occur. Seek immediate medical attention if you experience any of the following:

• Signs of infection: Fever, chills, cough, sore throat, or painful urination. Skyrizi can lower your ability to fight infections.
• Allergic reactions: Rash, itching, hives, swelling of the face, lips, tongue, or throat, or difficulty breathing.
• Liver problems: Jaundice (yellowing of the skin or eyes), dark urine, severe stomach pain, or persistent nausea/vomiting.

Your doctor will monitor you for side effects throughout your treatment.

Precautions and Warnings

Before starting Skyrizi, inform your doctor about:

• Any current infections or if you get infections often.
• Any upcoming vaccinations. You may need to stop Skyrizi before receiving certain live vaccines.
• Any other medical conditions you have, especially liver or inflammatory bowel diseases.
• All the medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements.
• If you are pregnant, planning to become pregnant, or breastfeeding.

Cost and Insurance Coverage

The cost of Skyrizi can be a significant consideration. Factors like your insurance plan, the dosage prescribed, and the duration of treatment all influence the overall price. Many patients in India explore options like:

• Insurance: Check with your health insurance provider about coverage for biologic medications.
• Manufacturer Support Programs: The manufacturer of Skyrizi may offer savings cards or patient assistance programs to help reduce out-of-pocket expenses.
• Hospital/Clinic Financial Aid: Some healthcare facilities provide financial counseling or assistance for patients undergoing expensive treatments.

It is advisable to discuss the cost and potential financial assistance options with your doctor's office or the hospital's billing department.

When to Consult Your Doctor

It's essential to maintain regular contact with your healthcare provider while on Skyrizi. Consult your doctor immediately if:

• You develop any signs of a new infection.
• You experience any severe or persistent side effects.
• Your condition does not seem to be improving or worsens.
• You have questions or concerns about your treatment.
