I had to go through applying via a site Humira provided. And i had to confirm I had commercial drug insurance coverage through my employer. But Abbvie covered my entire cost for $5 contribution a month from me.

Enbrel has a similar program if you have employer drug coverage. These drugs are so expensive - but enbrel is on the list of drugs congress will be negotiating a steeply discounted cost for.
… The Biden administration selected Enbrel as one of the first 10 drugs for Medicare drug price negotiations under the Inflation Reduction Act (IRA) in 2023. The negotiations are expected to take place in 2023 and 2024, with the negotiated prices going into effect on January 1, 2026. The Centers for Medicare and Medicaid Services (CMS) is expected to publish the maximum fair prices by September 1, 2024.

Good luck!
