How does Enbrel work?
Plaque psoriasis is a chronic autoimmune condition. It causes the immune system to mistakenly activate and trigger inflammation, leading to tissue damage and plaques on the skin.2
Enbrel is a type of biologic drug called a tumor necrosis factor-alpha (TNF-alpha) blocker. TNF-alpha is a type of chemical messenger that plays a key role in triggering inflammation. People with psoriasis have too much TNF-alpha. Enbrel works by blocking TNF-alpha, which in turn disrupts the cycle of inflammation and reduces psoriasis symptoms.1
What are the possible side effects?
The most common side effects of Entrel include:
- Injection site reactions, such as redness, itching, pain, swelling, bleeding, or bruising
- Sinus infections
Enbrel has a boxed warning, the strictest warning from the US Food and Drug Administration (FDA). It has this warning because:1
- It can increase your risk of serious infections
- Cancer has been reported in children and teens treated with Enbrel
These are not all the possible side effects of Enbrel. Talk to your doctor about what to expect when taking Enbrel. You also should call your doctor if you have any changes that concern you when taking Enbrel.
Other things to know
Enbrel is given as an injection under the skin. Your doctor may decide that you or a caregiver can give the injections at home. If so your doctor will train you or your caregiver on how to prepare, store, and inject Enbrel. Your doctor will also tell you how often you should use Enbrel.1
