INTACEPT 25 mg Injection contains etanercept, a medication used to treat various autoimmune and inflammatory conditions just in a lower dose. Etanercept works by inhibiting tumor necrosis factor (TNF), a substance in the body that causes inflammation. By blocking TNF, etanercept helps reduce inflammation, pain, and damage caused by certain conditions. Intacept 25 mg dose is often preferred in specific situations, such as for patients needing gradual dose escalation, children, or those who can't tolerate the higher 50 mg dose.
