Kevzara (Sarilumab) Interactions: What You Need to Know

Kevzara, with the active ingredient sarilumab, is a prescription medication used to manage certain rheumatic diseases, particularly rheumatoid arthritis, in adults and certain children with polyarticular juvenile idiopathic arthritis. While it offers significant benefits for managing these conditions, it's crucial to understand its potential interactions with other substances, including medications and alcohol. Understanding these interactions can help prevent adverse effects and ensure the safe and effective use of Kevzara.

What is Kevzara and How Does it Work?

Kevzara is a type of drug known as a monoclonal antibody. It works by targeting and blocking a specific protein in the body called interleukin-6 (IL-6). IL-6 plays a key role in inflammation, which is a major component of diseases like rheumatoid arthritis. By reducing the activity of IL-6, Kevzara helps to decrease inflammation, pain, and joint damage associated with these conditions.

Potential Drug Interactions with Kevzara

Drug interactions occur when one substance affects how another substance works in the body. This can lead to unexpected side effects or reduce the effectiveness of one or both substances. It is essential to discuss all medications, supplements, and over-the-counter drugs you are taking with your doctor or pharmacist before starting Kevzara.

Corticosteroids (Steroids)

Kevzara can interact with corticosteroids, a class of drugs commonly used to treat inflammatory conditions like rheumatoid arthritis and polymyalgia rheumatica. Examples of corticosteroids include prednisone (Rayos) and methylprednisolone.

Risks of Combining Kevzara and Corticosteroids:

• Increased Risk of Infections: Both Kevzara and corticosteroids can weaken the immune system, making you more susceptible to infections. Combining them can further increase this risk.
• Gastrointestinal Perforation: Both medications can cause a tear in the stomach or intestines (gastrointestinal perforation). Taking them together can elevate this risk, especially if you have a history of diverticulitis or ulcers in your stomach or intestines.

It is important to note that Kevzara carries a boxed warning regarding the risk of serious infections. If you experience symptoms of an infection, such as fever, chills, cough, sore throat, or shortness of breath, contact your doctor immediately. Similarly, seek immediate medical attention if you develop severe abdominal pain, fever, nausea, or vomiting, which could indicate a gastrointestinal perforation.

Statins

Statins are medications used to lower high cholesterol levels. Kevzara can interact with certain statins, such as atorvastatin (Lipitor).

How the Interaction Works:

• When taken together, Kevzara can cause your body to break down certain statins more rapidly. This can lead to lower levels of the statin in your bloodstream, potentially making the medication less effective in managing cholesterol.

Increased cholesterol levels are also a potential side effect of Kevzara itself. Therefore, close monitoring of your cholesterol levels may be necessary if you are taking both Kevzara and a statin.

Other Potential Drug Interactions

While the table provided in the source material is not exhaustive, it's crucial to be aware that other medications might interact with Kevzara. Always inform your doctor about every medication you are taking, including:

• Other immunosuppressants
• Certain antibiotics
• Antifungal medications
• Other disease-modifying antirheumatic drugs (DMARDs)

Your doctor will assess the potential risks and benefits of combining Kevzara with other medications based on your individual health status.

Kevzara and Alcohol Interaction

Kevzara is not known to have a direct interaction with alcohol. However, both Kevzara and alcohol can affect the liver.

• Liver Enzyme Levels: Kevzara can increase liver enzyme levels, which can be an indicator of liver damage.
• Alcohol's Effect on the Liver: Consuming large amounts of alcohol can also damage the liver.

Therefore, drinking alcohol while taking Kevzara may increase your risk of liver damage. It is advisable to discuss your alcohol consumption habits with your doctor. They can provide personalized guidance on whether it is safe for you to consume alcohol during your treatment with Kevzara.

Contraindications and Allergic Reactions

The only known contraindication for Kevzara is a history of an allergic reaction to Kevzara or any of its ingredients. If you have experienced an allergic reaction in the past, your doctor will likely prescribe an alternative treatment. Signs of an allergic reaction can include rash, itching, swelling, dizziness, and difficulty breathing.

When to Consult Your Doctor

It is essential to maintain open communication with your healthcare provider throughout your Kevzara treatment. Consult your doctor or pharmacist if you:

• Are considering starting Kevzara and are taking other medications or have existing health conditions.
• Experience any new or worsening symptoms while taking Kevzara, especially signs of infection or gastrointestinal issues.
• Have questions about potential interactions between Kevzara and alcohol or other substances.
• Notice any unusual side effects or changes in your health.

Your doctor is your best resource for managing your health and ensuring the safe and effective use of Kevzara. They can help you navigate potential interactions and adjust your treatment plan as needed.
