Understanding the Severe Side Effects of Humira

## Introduction Humira (adalimumab) is a biologic medication widely used to treat various autoimmune conditions such as rheumatoid arthritis, Crohn's disease, psoriasis, psoriatic arthritis, ankylosing spondylitis, and ulcerative colitis. While it has been a game-changer for many patients, offering relief from debilitating symptoms, understanding its severe side effects is crucial for informed decision-making. ## How Humira Works Humira is a TNF (tumor necrosis factor) blocker that helps reduce inflammation and other autoimmune disease symptoms by inhibiting TNF, a substance in the body that causes inflammation and is involved in the immune response.

Non-Hodgkin's lymphoma 2. Skin cancer (melanoma and non-melanoma) 3. Leukemia 4. Hepatosplenic T-cell lymphoma (especially in young patients) For more information, visit the [American Cancer Society](https://www.cancer.org/). ### Neurological Complications > "Multiple sclerosis-like symptoms, seizures, and inflammation of the nerves of the eyes have been reported in patients taking TNF blockers, including Humira." - *FDA Warning* Common neurological side effects include: * Numbness or tingling * Vision problems * Weakness in legs * Dizziness * Seizures * Optic neuritis ### Blood Disorders Humira can affect blood cell production: | Condition | Symptoms | |-----------|----------| | Anemia | Fatigue, weakness | | Leukopenia | Frequent infections | | Thrombocytopenia | Easy bruising, bleeding | ### Liver Problems Warning signs include: * Yellowing of skin or eyes * Dark-colored urine * Severe abdominal pain * Unusual fatigue * Elevated liver enzymes * Hepatitis ### Cardiovascular Concerns Patients should watch for: - Shortness of breath - Swelling of ankles or feet - Sudden weight gain ## Monitoring and Management ### Preventive Measures 1.
