Prescribed Certolizumab? Here Is Everything You Need to Know About Your Treatment

Living with a long-term health condition that causes painful joints, skin rashes, or gut trouble can feel overwhelming. When standard medicines do not bring enough relief, your doctor might recommend a biologic medicine called certolizumab pegol to calm your immune system down.

Because this medicine works deep inside your body to change how your immune system behaves, learning how it works is very important. This guide will walk you through everything you need to know about taking certolizumab safely every single day.

What Is Certolizumab and What Is It Used For?

Simply put, certolizumab is a prescription medicine that helps control parts of your body's immune system. Sometimes your immune system mistakenly attacks healthy tissues in your body, causing painful swelling and lasting damage.

Doctors prescribe certolizumab to help calm this overactive response for several specific medical conditions. A very common brand name you might see on your prescription package is Cimzia.

Here are the primary health conditions that doctors treat with certolizumab:

• Rheumatoid Arthritis: Your own immune cells attack your joint linings, causing painful swelling and stiff joints in the morning.
• Psoriatic Arthritis: This is a painful joint inflammation that affects people who already live with the skin condition psoriasis.
• Ankylosing Spondylitis: This inflammatory condition mainly affects your spine, causing stiffness and making your spinal bones fuse together over time.
• Non-Radiographic Axial Spondyloarthritis: This condition causes chronic back inflammation, even though regular X-rays do not show obvious structural bone damage yet.
• Crohn's Disease: This is a long-term inflammatory condition that affects your digestive tract, especially your small and large intestines.
• Plaque Psoriasis: This common skin condition creates thick, red patches of skin covered with silvery scales that flake off.

Your doctor might sometimes prescribe this medicine for other health issues not listed here. If you have any questions about why you need this medicine, ask your doctor or pharmacist for clear answers.

What to Tell Your Doctor Before Starting Certolizumab.

Before you take your first dose of certolizumab, you must share your complete medical history with your doctor. This medicine affects your immune system, so it is not safe or suitable for every person.

Tell your doctor right away if any of the following health conditions apply to you:

• You currently have cancer or have battled cancer in the past.
• You live with diabetes mellitus or blood sugar regulation problems.
• You have Guillain-Barre syndrome or any nerve-related medical condition.
• You suffer from heart failure or a weakened heart muscle.
• You currently have hepatitis B or have had it in the past.
• You have any known primary weakness in your immune system.
• You catch frequent infections or have an active infection right now.
• Your routine blood tests show low blood counts like low white blood cells or platelets.
• You have multiple sclerosis or another demyelinating nervous system disorder.
• You recently received a vaccine or plan to get one soon, especially live vaccines.
• You have tuberculosis, a positive TB skin test, or close contact with someone who has TB.
• You have allergies to certolizumab, latex, rubber, foods, dyes, or preservatives.
• You are pregnant, planning to become pregnant, or trying to start a family.
• You are currently breastfeeding or plan to breastfeed your baby.

Sharing these details helps your doctor decide if this medicine is safe for you. Your doctor can also plan extra safety monitoring if needed.

How to Use Certolizumab Safely.

Certolizumab is given as an injection right underneath your skin, known as a subcutaneous injection. Most of the time, a doctor will give you this shot at a clinic or hospital.

Sometimes, your doctor will teach you or a caregiver how to give these injections at home. If you inject at home, make sure you learn the exact preparation and injection steps clearly.

Always take this medicine exactly as your doctor prescribes, following the correct schedule and dose. Never change your dose or take it more often without talking to your medical team first.

Important Sharps Disposal Rule:

Never throw used needles and syringes into your household trash bin. Always place them into a puncture-proof sharps container. Ask your pharmacist or doctor for a proper container if you do not have one.

When your pharmacy dispenses this medicine, they will include a medicine Guide patient leaflet. Read this guide carefully every time you pick up a refill because it contains updated safety details.

If children need this medicine, a pediatric specialist must manage the treatment carefully. Children require strict medical supervision and specialized dosing adjustments.

If you accidentally take too much medicine, contact your local poison control center or emergency room right away. Never share your prescription medicine with anyone else, even if they have the exact same symptoms you do.

What to Do If You Miss a Dose.

Taking your certolizumab injections on time is very important to keep your condition under control. If you miss your scheduled injection day, contact your doctor or nurse right away for guidance.

If you give yourself injections at home and miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely.

Never take a double dose or extra medicine to make up for a missed injection. If you feel confused about what to do after missing a dose, call your pharmacist for clear instructions.

Other Things That Can Interact With Certolizumab.

Certain medicines and substances can interact poorly with certolizumab, causing unwanted health problems. Do not take certolizumab alongside certain other specialized treatments.

Avoid taking certolizumab if you are currently using any of the following medical products:

• Other biologic medicines like abatacept, adalimumab, anakinra, etanercept, or golimumab.
• Additional biologics such as infliximab, natalizumab, rituximab, secukinumab, or tocilizumab.
• Ustekinumab or other immune-modulating biologic therapies.
• Live vaccines of any kind.
• Tofacitinib or similar targeted synthetic drugs.

This list may not include every possible drug interaction. Tell your doctor about every single product you take, including prescription drugs, over-the-counter medicines, herbal supplements, and vitamins.

Be sure to also tell your doctor if you smoke tobacco, drink alcohol, or use recreational substances. These lifestyle factors can interact with your treatment plan.

Important Safety Precautions While Taking Certolizumab.

You will need regular check-ups with your doctor to see how well the medicine is working. If your symptoms do not improve or get worse, let your doctor know right away.

Before you start taking certolizumab, your doctor will test you for tuberculosis. If you test positive or need treatment for latent TB, you must finish those TB medicines completely before taking certolizumab.

When to Seek Emergency Medical Help.

Call 911 (US/Canada), 999 (UK), or go to your nearest Emergency Department right away if you experience severe shortness of breath, sudden chest pain, swelling of your face, lips, or tongue, signs of a severe allergic reaction, or sudden high fever with shaking chills.

Because certolizumab lowers your immune system's fighting power, you can catch infections much more easily. Stay away from people who are sick with colds, flu, or other contagious illnesses whenever possible.

Discuss the long-term risk of certain cancers openly with your doctor. Taking immune-modulating biologic medicines can slightly increase your risk of developing specific types of cancer.
