Actemra (tocilizumab) is an interleukin-6 (IL-6) receptor antagonist. It treats several inflammatory conditions in children and adults, including rheumatoid arthritis. It works by blocking IL-6, a chemical released by the immune system that causes inflammation and fever. Actemra (tocilizumab) is given as an injection (either through the veins or under the skin), typically weekly or every few weeks, depending on the condition you're taking it treat. Side effects include a higher risk of infections and headache.

Tips for using Actemra (tocilizumab) injections under the skin at home
Actemra (tocilizumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Actemra (tocilizumab) can make it more difficult for your body to fight off infections. This raises your risk of bacterial, viral, or fungal infections. The risk is higher for people who are taking or have recently taken other medications that weaken the immune system. Additionally, Actemra (tocilizumab) might reactivate (wake up) certain viruses that are already in your body, such as tuberculosis (TB) or hepatitis B. If you develop an infection, your provider will likely ask you to stop taking Actemra (tocilizumab) until your body fights off the infection. Let your provider know if you experience symptoms of these infections, such as fever, cough, difficulty breathing, or weakness.
Actemra (tocilizumab) might raise your risk or tears or damage to the stomach or intestines. Your risk can be higher if you have a history of certain stomach problems or are also taking NSAIDs. Stop taking Actemra (tocilizumab) and contact your provider right away if you experience stomach pain or blood in your urine or stool.
Though rare, Actemra (tocilizumab) can cause serious liver problems that can lead to liver failure. This can happen months to years after starting the medication. To be safe, your provider will order blood tests to check your liver health before you start Actemra (tocilizumab) and regularly during treatment to make sure your liver is working properly. Get medical attention right away if you notice swelling of your stomach, stomach pain, yellowing of your skin or the whites of your eyes, stool changes (black, tarry, or bloody stools), nausea, vomiting, confusion, or dark or brown urine. You might need to stop using the medication to prevent further liver damage.
Severe allergic reactions to Actemra (tocilizumab) are possible, including life-threatening reactions like facial swelling, shock, and anaphylaxis (closing of the throat). If you notice dizziness, a choking sensation, nausea, swelling around your eyes, swelling of the lips or tongue, or difficulty breathing after using Actemra (tocilizumab), get medical attention right away.
Although rare, people taking Actemra (tocilizumab) have experienced lower WBC and platelet counts. This can raise the risk of serious infections and bleeding. Because of this, your provider will check your blood cell counts before you start Actemra (tocilizumab) and regularly while you're taking this emdication. If your blood cell counts drop too low, your provider might ask you to stop taking Actemra (tocilizumab). If you develop any signs of infection (e.g., fever, tiredness, chills, cough, trouble breathing) or signs of blood problems (pale skin, fast heart rate, lightheadedness, blood in your urine or stool), contact your provider right away.
Actemra (tocilizumab) can raise your cholesterol (a type of fat). Your provider might order cholesterol blood tests every 1 to 3 months while taking Actemra (tocilizumab) to check your cholesterol level. If it's high, your provider might prescribe you cholesterol medication. To prevent high cholesterol levels, make sure to exercise regularly and eat a balanced diet.
There's limited information available on the effects of Actemra (tocilizumab) on your body's response to vaccines, including live vaccines. Make sure your shots are up-to-date before starting Actemra (tocilizumab). Talk with your provider before you receive any vaccines while receiving Actemra (tocilizumab) treatment. Avoid getting live vaccines while you're taking Actemra (tocilizumab) because there's a risk that you can get sick from them.
Actemra (tocilizumab) is given as an infusion through the veins (intravenous or IV) over 1 hour. It can also be given as an injection under the skin (subcutaneous or SC).
Your provider will decide your dose based on how well the medication is working for you, your body weight, if it's being given as an IV or SC injection, and if it's causing side effects.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.

People who took Actemra in clinical trials didn't report weight gain as a side effect. It's possible, but if it does happen, it appears to be only small changes in weight. A small study looked at the body weight of people who took Actemra with methotrexate for rheumatoid arthritis. Results showed that people taking this combination gained about 2 pounds after 5 months of treatment. Speak with your provider if you experience unusual weight changes while you're taking Actemra.
No, hair loss wasn't a side effect reported by people using Actemra in clinical studies. If you notice hair loss while you're taking Actemra, contact your provider so they can help you figure out possible causes.
Taking Actemra might raise the risk of cancer because it's an immunosuppressant. And some people have developed cancer during clinical studies of Actemra, but it's unclear whether the cancer was caused by this medication. More research is needed to help us understand the link between Actemra and cancer. Talk to your provider about your options if taking Actemra concerns you.
How long it takes for Actemra to work depends on why you're taking Actemra. For example, a study of people who took Actemra IV infusions for rheumatoid arthritis showed that the medication worked in as early as 2 weeks for some people in easing RA symptoms. Another study of people who took Actemra SC (in addition to a 6-month steroid taper) for giant cell arteritis showed that more people who took Actemra stayed in remission after 1 year compared to those who received the steroid taper alone. Ask your provider if you're not sure how quickly you can expect Actemra to help improve your condition.
There isn't a specific amount of time you need to take Actemra for giant cell arteritis (GCA). Your provider will likely have you continue taking the medication as long as it's working well for you and you're not having side effects. In a clinical study, people who took Actemra for giant cell arteritis received treatment, along with a 6-month steroid taper, for 1 year. At the end of the year, results showed that Actemra continued to control GCA even after steroids were stopped. Ask your provider if you're not sure how long you need to continue Actemra.
How long Actemra stays in your system depends on how many doses you've received, how long you've been taking this medication, and whether you're receiving it as an infusion or as an injection under the skin. In general, it takes about 2 to 4 months for most of Actemra to leave your body after you've been taking this medication for a while. This timeframe is estimated based on the half-life of Actemra. Talk with your provider if you're not sure how long this medication stays in your body.
Actemra should be stored in the fridge (36°F to 46°F) at all times. But if you're traveling and don't have access to a fridge, the Actemra prefilled syringe and autoinjector can be stored at room temperature for up to 2 weeks.
Ask your provider if you can drink alcohol while taking Actemra. Alcohol isn't known to directly interact with Actemra or affect how well it works. But both Actemra and alcohol can raise your risk of liver damage, as well as weaken your immune system so that it's harder for your body to fight off infections. Your provider will likly recommend that you avoid alcohol or limit how much alcohol you drink while you're taking Actemra.
