Do Enbrel (etanercept) injections hurt?

Medically reviewed by Carmen Pope, BPharm. Last updated on May 26, 2025.

Official Answer by Drugs.com

Enbrel (etanercept) is a subcutaneous (under the skin) injection that is administered either once or twice a week and is approved to treat several inflammatory conditions such as psoriasis and rheumatoid arthritis. It belongs to the class of medicines called TNF inhibitors.

Enbrel, like most other biologics, is unable to be given orally because it is such an unstable molecule it barely gets absorbed. Which is why it needs to be given by injection.

People who give themselves Enbrel do report stinging for a short period (up to 20 seconds) after administration.

But there are several things you can do to make the process less painful.

How do I give myself an Enbrel injection?

Enbrel should be kept refrigerated at between 36°F to 46°F (2°C to 8°C) until it needs to be administered.

Each Enbrel autoinjector is administered just one time only.

Enbrel may be left unrefrigerated for a maximum of 14 days, as long as it is kept at room temperature between 68°F to 77°F (20°C to 25°C) and not exposed to light or a heat source. If Enbrel is not used within 14 days after being taken out of the fridge, throw it away in an approved sharps container.
