The experience after an Actemra (tocilizumab) infusion varies among individuals, but it is helpful to be prepared for common sensations and potential side effects. The infusion process itself typically lasts around an hour, during which you are monitored by a healthcare professional. The days and weeks that follow can bring a range of feelings, some of which are a normal part of the medication's effect, while others may signal a need for medical attention.
What to Expect Immediately After Your Infusion
Directly following the procedure, and for up to 24 hours, you may experience mild infusion-related reactions. While infusion reactions are relatively uncommon and most patients tolerate the treatment well, the infusion center staff will monitor you closely to manage any issues. Common reactions can include:
- Headache
- Dizziness
- Nausea
- Changes in blood pressure, which could be higher or lower than usual
- Flushing or skin rash
Patients are typically observed for a period after the infusion to ensure there are no immediate adverse reactions. It is crucial to immediately inform the staff if you experience chest pain, difficulty breathing, or severe swelling of the face, lips, or tongue, as these could be signs of a serious allergic reaction.
Common Side Effects in the Days Following
In the period after the initial 24 hours, other side effects may arise. These are generally mild and may decrease with subsequent infusions as your body adjusts to the medication. Some of these can include:
- Upper Respiratory Infections: Colds, sinus infections, or sore throats are among the most frequently reported side effects. Because Actemra works by suppressing the immune system, you are more susceptible to infections.
- Fatigue: Many patients report feeling more tired than usual after their infusions. Some people may feel this tiredness more acutely in the week leading up to their next scheduled infusion, as the medication's effects start to wane.
- Gastrointestinal Issues: Abdominal pain, diarrhea, and mouth sores are possible side effects.
- Headaches: While also a potential immediate reaction, headaches can persist or develop in the days following the infusion.
- Bruising and Bleeding: Some patients report easier bruising or bleeding, which relates to the potential for reduced platelet counts.
Serious Side Effects to Monitor For
While less common, some side effects of Actemra are serious and require immediate medical attention. It is important to be vigilant and know the warning signs.
Life-Threatening Infections
Actemra carries a Boxed Warning—the FDA's most serious warning—due to the risk of serious infections. These can be bacterial, viral, or fungal, and in rare cases, can be fatal. Symptoms to watch for include:
- Fever, chills, or persistent cough
- Flu-like symptoms, aches, and tiredness
- Weight loss
- Skin sores or wounds that don't heal
- Pain during urination or frequent urination
Gastrointestinal Perforation
This serious condition involves a hole or tear in the stomach or intestines. While rare, the risk is higher for those with a history of diverticulitis or ulcers, or those also taking NSAIDs or corticosteroids. Seek immediate medical care if you experience:
- Fever and persistent, severe abdominal pain
- A noticeable change in bowel habits
Liver Problems
Changes in liver enzymes are a known side effect and are monitored via blood tests. In rare cases, more serious liver damage can occur. Call your doctor immediately if you have:
- Yellowing of the skin or eyes (jaundice)
- Dark-colored urine
- Pain in the upper right abdomen
- Unusual fatigue or loss of appetite
Hypersensitivity Reactions
A serious allergic reaction can occur with any Actemra dose, regardless of past reactions. Signs include:
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or wheezing
- Severe rash, hives, or itching
Comparison of Common Actemra Infusion vs. Subcutaneous Injection Side Effects
Though the focus is on the infusion, it is helpful to note the differences in administration and related side effects.
| Feature | Intravenous (IV) Infusion | Subcutaneous (SC) Injection |
|---|---|---|
| Administration | Into a vein over approximately one hour at an infusion center. | Under the skin via a pre-filled syringe or autoinjector. |
| Typical Side Effects | Headaches, nausea, dizziness, blood pressure changes. | Pain, redness, swelling, or itching at the injection site. |
| Onset of Reactions | Infusion-related reactions can occur during or up to 24 hours after treatment. | Injection site reactions are typically immediate and mild. |
| Overall Risk Profile | Safety profile is generally consistent, though infusion-related reactions differ. | Overall safety profile is similar to the IV form. |
Managing Your Recovery Post-Infusion
To help manage how you feel after your Actemra infusion, consider the following strategies:
- Rest and Recuperate: Many people feel fatigued after the treatment. Plan for a quiet day with limited activity to allow your body to rest.
- Stay Hydrated: Drinking plenty of water both before and after your infusion can help minimize potential side effects like headaches and nausea.
- Eat Lightly: A light meal before your appointment can help maintain energy levels. If you feel nauseous afterward, try bland, easy-to-digest foods.
- Monitor Your Symptoms: Keep a journal of any side effects and their severity. This can help you identify patterns and discuss them with your healthcare provider.
- Communicate Openly: Report any side effects to your doctor or nurse. They can offer advice on managing symptoms, such as approving over-the-counter pain relievers for headaches, or adjusting your treatment plan if needed.
- Avoid Live Vaccines: Because Actemra is an immunosuppressant, it's essential to avoid live vaccines and close contact with individuals who have recently received them. Discuss your vaccination schedule with your provider.
- Check Bloodwork: Your doctor will regularly order blood tests to monitor for changes in liver function, cholesterol levels, and blood cell counts. Keeping these appointments is a critical part of your treatment safety.
Conclusion
While the prospect of an Actemra infusion can be intimidating, understanding potential outcomes is an empowering step in your treatment journey. The most common experiences are manageable, with many patients tolerating the infusion well or experiencing mild, temporary side effects such as headaches, fatigue, or upper respiratory symptoms. Serious side effects are rarer but require prompt attention. By adhering to post-infusion care instructions, monitoring your body closely, and maintaining open communication with your healthcare team, you can navigate your treatment with confidence. Your experience is unique, and keeping your provider informed of how you feel is the best way to ensure your safety and maximize the therapeutic benefits of Actemra.
