What You'll Learn
Enbrel's impact on the immune system
Enbrel (etanercept) is a prescription injection used to treat inflammation caused by certain autoimmune disorders. It is a type of drug called a tumor necrosis factor (TNF) blocker. TNF is a protein produced by the body that can cause inflammation (damage and swelling). Enbrel blocks TNF from working, decreasing inflammation.
Enbrel can cause mild or serious side effects. The more common side effects of Enbrel include respiratory infections, such as sinus infections or the flu, and injection site reactions, such as irritation, redness, discoloration, or pain. These side effects are usually mild and easily managed at home.
Serious side effects of Enbrel are rare but can include serious infections, allergic reactions, autoimmune reactions, blood disorders, neurological problems, and an increased risk of cancer. Enbrel lowers your body's ability to fight off infections, so infections are a common side effect. In clinical trials, 50% of people taking Enbrel had an infection over a 6-month period. Upper respiratory infections are the most common type of infection reported with Enbrel.
Enbrel can also increase the risk of serious or life-threatening infections, such as tuberculosis (TB). It can cause reactivated (pre-existing) TB or new TB if exposed, as it weakens the immune system. Before starting Enbrel, a doctor will test for TB and other serious infections, such as hepatitis B. They will also inquire about the patient's family history of cancer.
Serious allergic reactions can occur, which can be life-threatening and require immediate medical attention. Symptoms of a severe allergic reaction include swelling of the face, lips, mouth, tongue, or throat, trouble swallowing, and itching. Enbrel can also cause autoimmune reactions, such as lupus-like syndrome, which causes symptoms similar to lupus. Blood disorders, such as agranulocytosis, aplastic anemia, hemolytic anemia, low platelet levels (thrombocytopenia), and low white blood cell levels (leukopenia), have also been reported.
Neurological problems, including Guillain-Barré syndrome, multiple sclerosis, demyelinating disease, seizures, and optic neuritis (an eye condition that can lead to vision loss), have occurred rarely in people using Enbrel. A small number of people who used Enbrel have developed certain types of cancer, including leukemia, lymphoma, and skin cancer.

Allergic reactions
Enbrel (etanercept) is a prescription injection used to treat inflammation caused by certain autoimmune disorders, such as rheumatoid arthritis, psoriatic arthritis, and plaque psoriasis. While Enbrel can effectively manage these conditions, it may also cause various side effects, including allergic reactions that range from mild to severe.
Mild allergic reactions to Enbrel typically manifest as skin-related symptoms, such as a rash, itching, or hives. These reactions, while uncomfortable, are not life-threatening and often resolve without intervention. However, it is always advisable to consult a healthcare provider if any of these symptoms occur, as they can provide guidance on managing the reaction and ensuring your safety.
On the other hand, severe allergic reactions to Enbrel can be life-threatening and require immediate medical attention. Symptoms of a severe allergic reaction include:
- Swelling of the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs
- Trouble swallowing or throat tightness
- Breathing difficulties or wheezing
- Racing heart
- Fever or chills
- Stomach cramps
- Nausea or vomiting
- Dizziness, lightheadedness, or fainting
If you experience any of these symptoms after taking Enbrel, discontinue use and seek emergency medical help immediately. Do not wait for the symptoms to worsen, as prompt treatment is crucial in managing severe allergic reactions.
It is important to note that Enbrel can also increase the risk of infections, including serious and life-threatening infections. If you develop a fever, cough, flu-like symptoms, or other signs of infection while taking Enbrel, contact your healthcare provider right away. They may advise you to discontinue Enbrel temporarily or make adjustments to your treatment plan.

Nervous system problems
Enbrel (etanercept) is a prescription injection used to treat multiple conditions, including rheumatoid arthritis, psoriatic arthritis, and plaque psoriasis. It is classified as a tumor necrosis factor (TNF) blocker, which helps to reduce inflammation caused by certain autoimmune disorders.
While Enbrel is a helpful medication for many, it can cause a range of side effects, some of which are mild and temporary, while others are more serious. One of the serious side effects associated with Enbrel is nervous system problems. These issues are rare but can have significant impacts.
Guillain-Barré Syndrome
Guillain-Barré syndrome is a rare disorder where the body's immune system attacks the nerves. It can cause muscle weakness and even paralysis in severe cases. Enbrel may increase the risk of developing this syndrome or exacerbate existing cases.
Multiple Sclerosis
Multiple sclerosis (MS) is a nervous system disease where the protective covering of nerves is damaged, slowing or blocking electrical signals between the brain and the body. Enbrel has been associated with an increased risk of developing MS or experiencing MS relapses in those already diagnosed.
Demyelinating Disease
Demyelinating diseases are a group of conditions that affect the myelin sheath, a protective covering that surrounds and insulates nerves. Enbrel may contribute to the development or progression of these diseases, leading to nerve damage and impaired nerve function.
Seizures
Seizures are a result of sudden abnormal electrical activity in the brain, leading to uncontrollable muscle movements and, sometimes, loss of consciousness. Enbrel has been linked to an increased risk of seizures in a small number of patients.
If you experience any symptoms indicative of nervous system problems, such as vision changes, muscle weakness, changes in behavior or thinking, or seizures, it is imperative to seek immediate medical attention. Your healthcare provider can advise you on managing these side effects and determining whether Enbrel is the best treatment option for you.

Cancer risk
Enbrel (etanercept) is an injectable medication that treats inflammation caused by certain autoimmune disorders. It is prescribed for arthritis, psoriasis, and other conditions. While Enbrel is effective in managing these conditions, it is associated with several side effects, including an increased risk of cancer.
Additionally, Enbrel use has been associated with an increased risk of skin cancer. In clinical trials, there was a reported rate of 0.41 cases of skin cancer per 100 patient years of Enbrel use. This equates to approximately one case of skin cancer per 100 individuals taking Enbrel for two years. As a result, periodic skin examinations are recommended for individuals taking Enbrel to facilitate early detection of any potential skin cancer development.
The risk of cancer associated with Enbrel use is not limited to lymphoma and skin cancer. There have also been reports of leukemia, a type of blood cancer, occurring in individuals taking Enbrel. Furthermore, combining Enbrel with certain other medications, such as cyclophosphamide, has been linked to an increased risk of specific cancer types, including lung and breast cancer.
It is important to note that the overall risk of getting cancer from Enbrel use is generally low. However, certain individuals may have a higher risk. People with active rheumatoid arthritis may be at an elevated risk of developing lymphoma while taking Enbrel. Additionally, children and teenagers who use Enbrel may have an increased risk of developing cancer. Therefore, it is crucial to discuss any family history of cancer and undergo a thorough evaluation with a healthcare provider before starting Enbrel treatment.

Injection site reactions
Enbrel is a medication injected under the skin to treat certain autoimmune disorders. Injection site reactions are common, especially during the first few months of treatment. These reactions appear in the area where the injection is given. Common symptoms include redness, irritation, pain, swelling, itching, bruising, and bleeding.
These symptoms are usually mild and will go away on their own within 3 to 5 days. To ease the discomfort, you can try using a cool compress to soothe the area or take pain relievers. It is recommended to rotate injection sites by changing where you inject Enbrel each time to reduce the chance of injection site reactions.
If the symptoms persist or worsen, or if you experience fever, trouble breathing, or signs of bleeding, seek medical care immediately as these could be signs of a more serious condition or infection. Enbrel lowers your body's ability to fight off infections, so it is important to be vigilant about any potential symptoms.
It is important to note that injection site reactions typically decrease as you continue to use Enbrel. However, if you are concerned about injection site reactions or if they are bothersome, it is recommended to consult your healthcare provider. They can provide guidance on proper injection techniques and ensure that you are using Enbrel correctly.
