Questions about treatment in Illinois

How do I get into treatment quickly in Illinois?

Call a center on this page and ask for the next intake appointment; many can see new patients within days. If you cannot wait, some hospital emergency departments can start buprenorphine the same day. SAMHSA's free helpline, 1-800-662-4357, can also find openings near you.

Does Illinois Medicaid cover methadone and buprenorphine?

Yes. Federal law requires every state Medicaid program, including the one in Illinois, to cover medications for opioid use disorder along with counseling. Ask the center whether it accepts your Medicaid plan.

Can I get treatment in Illinois without insurance?

Yes. State-funded programs, community health centers and sliding-scale clinics treat people without insurance. It is also worth checking whether you qualify for Medicaid in Illinois, since many people do without knowing it.

Where can I get naloxone in Illinois?

Pharmacies sell naloxone nasal spray without a prescription. Many local health departments and community programs give it out free.
