Cimzia is given as a subcutaneous injection, which means it is injected just under the skin. The injection is typically administered in the thigh or abdomen. It is important to follow your healthcare provider’s instructions when giving yourself the injection at home.

Here are some general guidelines for using Cimzia:

1. Self-Administration: Your doctor or healthcare provider will show you how to properly inject Cimzia. You should receive training before performing the injection yourself. Follow the step-by-step instructions carefully.
2. Injection Sites: Rotate injection sites to avoid irritation or injury at the same site. Do not inject into areas that are red, bruised, or irritated.
3. Preparation: Before injecting, make sure the Cimzia syringe is at room temperature. Remove the syringe from the fridge and allow it to warm up for about 30 minutes. Do not heat it directly (e.g., by microwaving).
4. Proper Disposal: After administering the injection, dispose of the needle and syringe properly in a designated sharps container.
5. Missed Doses: If you miss a dose, follow your doctor’s advice on what to do. Usually, it is recommended to take the dose as soon as possible unless it’s almost time for the next one. In that case, skip the missed dose and continue with the regular dosing schedule.
6. Regular Monitoring: When using Cimzia, your doctor will likely schedule regular check-ups to monitor for side effects and assess the effectiveness of the treatment. Blood tests, imaging studies, and regular evaluations of your condition will help guide the treatment plan.

Cimzia works by targeting and blocking tumor necrosis factor-alpha (TNF-alpha), a cytokine (a type of protein) that plays a significant role in inflammation. In autoimmune diseases, the immune system mistakenly attacks healthy tissues, leading to chronic inflammation. TNF-alpha is one of the key drivers of this inflammation.

By inhibiting TNF-alpha, Cimzia helps reduce the inflammation associated with diseases like rheumatoid arthritis and Crohn’s disease. This reduction in inflammation can lead to less pain, less swelling, and a decreased risk of joint or tissue damage. Additionally, the medication can improve overall quality of life by preventing the symptoms of these chronic conditions from interfering with daily activities.

Like all medications, Cimzia can cause side effects. Not everyone will experience them, but it is important to be aware of possible side effects:

1. Infections: Since Cimzia suppresses the immune system, it may increase the risk of serious infections, including tuberculosis, bacterial infections, fungal infections, and viral infections.
2. Injection Site Reactions: Some people may experience pain, redness, or swelling at the injection site.
3. Headache: Headaches are a common side effect, particularly during the early stages of treatment.
4. Gastrointestinal Issues: Nausea, vomiting, or diarrhea can occur, especially during the beginning of treatment.
5. Rashes: Skin rashes may develop in some patients, though these are typically mild.
6. Liver Issues: In rare cases, Cimzia can cause liver problems, which may lead to jaundice (yellowing of the skin or eyes), dark urine, or abdominal pain.
7. Heart Problems: Some patients may experience heart failure or heart problems while on Cimzia, especially those with a history of heart disease.
8. Blood Disorders: Cimzia may cause low blood cell counts, which can increase the risk of infections or bleeding.

If you experience any serious side effects or signs of an allergic reaction (such as difficulty breathing, swelling of the face or throat, or a severe rash), seek immediate medical attention.

Before using Cimzia, there are several important warnings and precautions:

1. Infections: Since Cimzia weakens the immune system, you should not start treatment if you have an active infection. Your doctor may test for tuberculosis (TB) and other infections before starting treatment.
2. Pregnancy and Breastfeeding: Cimzia is classified as a pregnancy category C drug, meaning its safety during pregnancy is not fully established. It should only be used during pregnancy if the potential benefit justifies the potential risk. Cimzia can pass into breast milk, so talk to your doctor if you plan to breastfeed.
3. Liver Disease: People with liver disease should be closely monitored while on Cimzia, as the medication may cause liver problems in some cases.
4. Heart Disease: Cimzia may worsen heart failure or cause heart-related side effects. Inform your doctor if you have any history of heart disease or heart failure.
5. Cancer Risk: TNF inhibitors like Cimzia may increase the risk of developing certain cancers, such as lymphoma. This risk should be discussed with your doctor before starting treatment.

Cimzia may interact with other medications, and it is important to inform your doctor about all the medications you are currently taking. Some key drug interactions include:

1. Other TNF Inhibitors: Combining Cimzia with other TNF inhibitors (like etanercept, infliximab, or adalimumab) is not recommended, as it may increase the risk of serious infections and other side effects.
2. Immunosuppressive Medications: Drugs that suppress the immune system, such as methotrexate or azathioprine, can interact with Cimzia. Combining these medications may increase the risk of infections or decrease the effectiveness of treatments.
3. Live Vaccines: Live vaccines (such as the measles, mumps, and rubella vaccine) should be avoided while taking Cimzia because the medication can weaken the immune system, making it harder for the body to fight off infections.
4. Medications for Infections: If you are being treated for an infection, be sure to inform your doctor, as certain infections can worsen while using Cimzia. Your doctor may decide to delay treatment with Cimzia until the infection is resolved.
5. Other Immunomodulatory Drugs: Medications that affect the immune system, such as corticosteroids, may interact with Cimzia, leading to increased susceptibility to infections.

Always talk to your doctor before starting any new medications while using Cimzia, including over-the-counter drugs and supplements, to avoid any harmful interactions.

Cimzia dosage depends on the condition being treated. The usual starting dose is 400 mg, given as two 200 mg injections at weeks 0, 2, and 4. After that, the maintenance dose is either 200 mg every 2 weeks or 400 mg every 4 weeks.

Different diseases may require slightly different schedules, such as for rheumatoid arthritis, Crohn’s disease, or psoriasis. Older adults usually don’t need a different dose but may be monitored closely.

Always follow your doctor’s instructions and never change the dose on your own. Missing doses can affect how well the medicine works.

Cimzia is a prescription-only medicine, meaning you must get it from a doctor. You cannot buy it without a medical prescription. Your doctor will first check your health, review your medical history, and run tests like TB and hepatitis B screening.

Only certain specialists, like rheumatologists or dermatologists, can prescribe Cimzia. Insurance companies may also ask for extra approval (prior authorization) before covering the cost.

You’ll need regular checkups and lab tests while using Cimzia. The prescription is not permanent it must be renewed regularly, usually every month or two.
