How to use
Enbrel comes in several different forms, but all forms of the drug are given by subcutaneous injection.
You’ll likely get your first Enbrel injection at your doctor’s office. Your doctor or pharmacist may then show you how to give yourself Enbrel injections at home. Enbrel injections can be given in your thigh, upper arm, or belly (except for within 2 inches of your belly button).
The Enbrel website contains detailed step-by-step instructions and videos on how to use Enbrel, depending on the form of the drug your doctor prescribed for you.
How often to use
For treating psoriatic arthritis, it’s recommended that you get one 50-mg Enbrel injection every week. You should try to have your Enbrel injections on the same day each week. This helps keep a stable level of the medication in your body.
Below are some frequently asked questions about using Enbrel to treat psoriatic arthritis.
Can Enbrel relieve joint pain?
In a clinical study, adults with psoriatic arthritis treated with Enbrel reported better relief of joint pain compared with people who received a placebo.* Joint pain was defined as tenderness and swelling in joints.
If you have additional questions about Enbrel and relieving joint pain, talk with your doctor or pharmacist.
* A placebo is a treatment with no active drug.
Can I use NSAIDs together with Enbrel to treat psoriatic arthritis?
As long as your doctor approves, it’s safe to take nonsteroidal anti-inflammatory drugs (NSAIDs) with Enbrel. There aren’t any known drug interactions between Enbrel and NSAIDs.
When taken for psoriatic arthritis, NSAIDs may help relieve joint swelling and morning stiffness, and they may help improve joint range of motion. Examples of NSAIDs include:
Although many NSAIDs are available over the counter, it’s very important that you don’t take these medications with Enbrel without first talking with your doctor. Your doctor can work with you to determine the best treatments for your psoriatic arthritis.
Enbrel is approved to treat psoriatic arthritis. This is a type of arthritis that people with psoriasis may have. The condition causes joint pain and swelling, as well as psoriasis plaques on your skin. Plaques are scaly, discolored patches of skin.
Psoriatic arthritis is caused by your immune system attacking certain tissues in your body, such as your joints. This causes inflammation (damage and swelling).
The way Enbrel works
Enbrel contains the active drug etanercept. Etanercept works by blocking a protein called tumor necrosis factor (TNF). TNF is a protein produced by your body that causes inflammation. People with psoriatic arthritis have higher levels of TNF in their joints, which causes too much inflammation in the affected area.
Enbrel lowers the amount of inflammation in your body, including in your joints, by blocking TNF. This can help reduce symptoms of psoriatic arthritis.
How long does it take for Enbrel to work for psoriatic arthritis?
Enbrel starts working to treat psoriatic arthritis as soon as you have your first injection. But you may not notice any improvements in your symptoms for a few weeks after you start the drug. In a clinical study, people taking Enbrel reported an improvement in their psoriatic arthritis symptoms 4 weeks after they began taking the drug.
It can be hard to predict how quickly Enbrel may work to treat psoriatic arthritis, and this may differ in each person. If you have questions about how to evaluate whether Enbrel is working for you, talk with your doctor.

Researchers compared how people rated certain psoriatic arthritis symptoms before and after 6 months of treatment. These symptoms included joint pain and the number of swollen and tender joints people had. For treatment, people took either Enbrel or a placebo (a treatment with no active drug).*
At the end of the study, the people who’d taken Enbrel reported better improvement in their psoriatic arthritis symptoms compared with the people who’d received a placebo.

Before you use Enbrel, there’s some important information to keep in mind. The drug may not be a safe option for you if you have certain medical conditions or other factors that affect your health. Some of these are mentioned below.

Serious infections. Enbrel works by weakening your immune system. For this reason, you may have an increased risk for developing serious infections while taking Enbrel. In some cases, these infections have been serious enough to lead to hospitalization and, rarely, death.
If you develop any symptoms of a serious infection while taking Enbrel (such as fever, nausea, vomiting, or diarrhea), contact your doctor right away. Before you start treatment, your doctor will test you for tuberculosis. If your test result is positive, your doctor will likely treat your infection before you start taking Enbrel. And, as you’re taking Enbrel, your doctor will watch for any signs or symptoms of serious infections. If you develop a serious infection, your doctor may decide to have you stop taking Enbrel.
Cancers. In children and young adults taking Enbrel, there have been reports of certain types of cancers, such as lymphoma (a type of blood cancer). People with very severe psoriasis or rheumatoid arthritis were at higher risk for developing cancer than those whose condition was mild or moderate. If you have concerns about your cancer risk, or if you develop any possible symptoms of cancer while taking Enbrel, talk with your doctor.
In addition to boxed warnings, Enbrel has other warnings.
