The standard recommended dosage of Actemra for treating rheumatoid arthritis is 4 mg per kg of body weight. When used for systemic idiopathic juvenile arthritis, the dosage will also be based on weight. Your healthcare provider will administer this prescription medication intravenously (via an IV infusion, also called an IV drip) once every four weeks.
An Introduction to Actemra DosingThe dose of Actemra® (tocilizumab) your healthcare provider recommends will vary, depending on how you respond to the medication (especially if you develop certain side effects) and on your weight. As is always the case, do not adjust your dosing schedule (by missing or canceling doses) unless your healthcare provider specifically instructs you to do so.
Recommended Dosage of Actemra for Rheumatoid ArthritisThe recommended starting dose of Actemra for rheumatoid arthritis treatment is 4 mg per kg (about 1.8 mg per pound) once every four weeks. Your healthcare provider may increase the amount up to 8 mg per kg (about 3.6 mg per pound) once every four weeks. The medication is administered intravenously (via an IV infusion, also known as an IV drip) lasting one hour.
The maximum dosage is 800 mg per infusion.
Your healthcare provider should check your liver function and blood cell counts (using standard blood tests) before you start Actemra and periodically thereafter. If your liver enzymes are too high or your blood cell counts are too low, your dosage may need to be reduced (in mild cases), or you may need to stop taking this medication altogether (for more severe cases).
