Ten things to note during Adalimumab injection

Adalimumab is a fully humanized monoclonal antibody targeting tumor necrosis factor--α (TNF-α). It is widely used in the treatment of a variety of autoimmune diseases, including rheumatoid arthritis, psoriasis, ankylosing spondylitis, etc. Due to its immunomodulatory effect, patients need to pay special attention to many aspects while using adalimumab to ensure the safety and efficacy of treatment. This article will introduce in detail the top ten precautions during adalimumab injection to help patients use the drug scientifically and maximize the effect of the drug.

1. Strictly follow the doctor’s instructions and inject on time

Adalimumab is usually administered by subcutaneous injection. The frequency of administration varies depending on the condition and specific regimen, but is usually once every two weeks. Patients should strictly abide by the dosage and schedule prescribed by the doctor and avoid missing injections or adjusting the medication time at will. Regular medication can ensure stable drug concentration in the body, thereby maintaining the therapeutic effect.

2. Pay attention to the selection and hygiene of the injection site

The injection site is usually the skin on the abdomen, thigh, or outside of the upper arm. Repeated injections at the same site should be avoided for each injection to prevent local skin induration or irritation. Before injecting, be sure to disinfect the injection site with an alcohol cotton ball to keep the skin clean and prevent infection. Injection equipment should be kept sterile and disposed of promptly after use.

3. Monitoring the risk of infection

By inhibiting TNF-α, adalimumab may reduce the body's resistance to infection and increase the risk of tuberculosis, pneumonia, viral infections, etc. Tuberculosis screening (e.g., tuberculin test, chest X-ray) should be performed before use, and medication should be delayed if there is active infection. If symptoms such as fever, cough, and frequent urination occur during treatment, you should seek medical treatment in time.

4. Pay attention to vaccination contraindications

Live vaccinations are generally contraindicated during treatment with adalimumab to prevent the risk of infection caused by the vaccines. Although inactivated vaccines can be used, the immune response may be weakened. It is recommended that patients complete necessary vaccinations before treatment and should consult their doctor for specific plans.

5. Perform regular hematology and liver function tests

Long-term use of adalimumab may cause hematological abnormalities (such as leukopenia), liver function damage and other side effects. Patients should undergo regular blood routine and liver function tests to detect abnormalities promptly and adjust treatment plans.

6. Be aware of allergies and injection reactions

Some patients may experience local redness, swelling, itching, and pain during or after the injection, and a few may experience allergic reactions, such as difficulty breathing, facial swelling, etc. If severe discomfort occurs, stop taking the medication and seek medical advice immediately.

7. Avoid abuse with other immunosuppressants

When adalimumab is used in combination with other immunosuppressants (such as methotrexate and cyclosporine), it must be strictly under the guidance of a doctor to avoid excessive suppression of the immune system and increase the risk of infection. Patients should not take multiple immunosuppressive drugs together without permission.

8. Use with caution during pregnancy and lactation

Adalimumab can pass through the placental barrier, and its use by pregnant women may affect the fetal immune system, so it should be used with caution. Breastfeeding women also need to weigh the pros and cons when taking medication and follow the doctor's advice. Patients who plan to become pregnant or breast-feeding should inform their doctor in advance.

9. Storage and transportation precautions

Adalimumab should be stored refrigerated to avoid freezing. Avoid high temperature or direct sunlight during transportation to ensure drug quality. Patients should properly store injections according to drug instructions to avoid misuse or deterioration.

10. Pay attention to mental health and lifestyle adjustments

Long-term chronic diseases and injection treatments may affect patients' mental state. They should maintain a positive attitude and arrange their lives reasonably. Eating a balanced diet, exercising moderately, avoiding tobacco and alcohol, and improving physical fitness will help improve the treatment effect and quality of life.

In summary, the use of adalimumab requires patients to cooperate closely with their doctors, abide by medication instructions, and do infection prevention and control and regular examinations. Only by fully understanding and paying attention to the above matters can we ensure the safe and effective use of drugs and help patients improve disease symptoms and restore a healthy life. In case of abnormal situations, professional medical staff should be consulted in time to ensure smooth treatment.
