Understanding Actemra: Benefits, Dosage, and Side Effects #
Actemra is a powerful medication designed to control inflammation and alleviate symptoms associated with autoimmune diseases, including rheumatoid arthritis, vasculitis, and juvenile idiopathic arthritis. This medication should only be used under the guidance of a healthcare professional. The active ingredient in Actemra is tocilizumab, which works by inhibiting the production of interleukin 6 (IL-6), a substance that triggers inflammatory responses in the body. Excessive IL-6 can lead to severe inflammation, causing tissue damage and symptoms of autoimmune diseases.

Actemra for Pregnant and Breastfeeding Women #
Actemra falls under Category C for pregnant women, indicating that animal studies have shown adverse effects on the fetus, but there are no adequate studies on pregnant humans. Actemra should only be used when the potential benefits justify the potential risks to the fetus. It’s unclear if Actemra passes into breast milk, so breastfeeding mothers should consult their doctors before using this medication.
Important Considerations Before Using Actemra #
Before starting Actemra, it’s crucial to consider the following points:

- Mention any ongoing or frequent infections, such as fever, chills, cough, mouth sores, diarrhea, or painful urination. Also, inform about any chronic infections like tuberculosis or hepatitis B.

- Avoid contact with individuals with easily transmissible infections or those recently vaccinated with live vaccines.
- Notify your healthcare provider about any planned surgeries, including dental procedures, while using Actemra.
- Report all medications, supplements, or herbal products you are currently taking to avoid potential drug interactions.
- Inform your doctor if you are pregnant, breastfeeding, or planning pregnancy. Also, if using hormonal contraceptives, as Actemra can reduce their effectiveness.
