Actemra Pen

Actemra Pen is a prescription medication used to treat moderate to severe rheumatoid arthritis (RA) and other autoimmune conditions. It contains the active ingredient tocilizumab and is administered via subcutaneous injection. Here is some detailed information about Actemra Pen that patients should know:

Dosage and Administration:

Actemra Pen is available in a pre-filled, single-use pen that contains either 162 mg or 324 mg of tocilizumab. The exact dosage and administration schedule will depend on the patient's weight and the severity of their condition, and should be determined by a healthcare provider.

Actemra Pen should be injected subcutaneously (under the skin) in the abdomen or thigh by the patient or a caregiver. The injection site should be rotated each time to reduce the risk of skin reactions. The medication should be refrigerated until use and allowed to come to room temperature for 30 minutes before injecting.

It's important to follow the instructions for use provided with the medication and to never inject more than the prescribed dose. If a dose is missed, it should be injected as soon as possible, and the regular schedule should be resumed.

Possible Side Effects:

As with any medication, Actemra Pen may cause side effects. The most common side effects reported include upper respiratory tract infections, headache, and injection site reactions such as redness, swelling, or pain. These side effects are usually mild to moderate in severity and resolve on their own.

However, some patients may experience more serious side effects, including liver problems, decreased blood cell counts, and infections such as tuberculosis. Patients should seek medical attention right away if they experience any signs of an allergic reaction, such as difficulty breathing, swelling of the face or throat, or hives.


Before starting Actemra Pen, patients should inform their healthcare provider of any medical conditions they have, especially a history of infections or liver disease. Actemra Pen should not be used in patients with active infections or a history of allergic reactions to tocilizumab or any of its ingredients.

Patients taking Actemra Pen may have an increased risk of serious infections and should be monitored closely for signs of infection during treatment. They should also be tested for tuberculosis before starting the medication and periodically during treatment.

Pregnant or breastfeeding women should talk to their healthcare provider before taking Actemra Pen, as its effects on fetal development and milk production are unknown.


Actemra Pen is a valuable treatment option for patients with moderate to severe rheumatoid arthritis and other autoimmune conditions. With proper dosage and administration, patients can benefit from its therapeutic effects while minimizing the risk of side effects. As always, patients should discuss any questions or concerns with their healthcare provider before starting any new medication.
