Treatment for opioid use disorder in Denver
Denver is one of the few large U.S. cities where overdose deaths kept rising in 2025 while the national curve bent down. Preliminary city figures show 515 drug overdose deaths in Denver last year and a roughly 24 percent jump in fatal fentanyl overdoses, with about two-thirds of all overdose deaths involving fentanyl (Denver Department of Public Health and Environment, 2026). Effective medication treatment is available across the metro at both opioid treatment programs and office-based providers, and a strong network of harm reduction services operates alongside it. The clinics listed above serve Denver County and nearby Westminster, Littleton, Lakewood, Aurora, and Boulder. To start, browse the listings or call the helpline at the top of the page.
Your medication and setting options
Three medications are approved to treat opioid use disorder, and where you receive them depends on which one fits.
Methadone is dispensed only through a federally certified opioid treatment program (OTP), sometimes called a methadone clinic. It is not available at retail pharmacies for OUD. Most Denver-area OTPs also offer counseling and case management on site.
Buprenorphine, including the combination product Suboxone and the monthly injection Sublocade, can be prescribed in an ordinary doctor’s office by any clinician with a standard DEA registration, then filled at a pharmacy. This office-based pathway (sometimes called OBOT) became broadly available after the federal X-waiver was eliminated in 2023, and it is widely used across Denver primary care, addiction medicine, and behavioral health clinics. Buprenorphine is also offered inside OTPs.
Naltrexone, including the monthly Vivitrol injection, blocks opioids rather than activating their receptors. Any licensed prescriber can offer it, but treatment can only start after a person has been off opioids for a set time, which a clinician will time carefully. How methadone and buprenorphine compare can help you sort through which medication fits your situation. The right choice is one you make with a clinician based on what you have used, your medical history, your insurance, and how much daily structure you want.
Getting started: what intake looks like
An OTP intake usually includes a medical assessment, a substance use history, urine drug testing, a tuberculosis screen, and a same-day or next-day first methadone dose for people who qualify. Federal rules updated in 2024 also allow OTPs to begin methadone treatment through a telehealth visit in some cases. For buprenorphine, the main thing to plan with your clinician is timing. Starting buprenorphine too soon after using fentanyl can trigger sudden, severe withdrawal called precipitated withdrawal, because fentanyl lingers in the body longer than older opioids. Because fentanyl is involved in most Denver overdose deaths, clinicians here are familiar with this and often use a slower start or a micro-dosing protocol. Ask before your first appointment whether the clinic offers a same-day or next-day induction. See methadone treatment for fentanyl addiction for more on what to expect.
Take-home doses, telehealth, and current rules
Two recent federal changes affect day-to-day treatment. SAMHSA’s 2024 revision of 42 CFR Part 8 made permanent up to a 28-day supply of take-home methadone for patients who are stable in treatment, with a graduated schedule earlier on, and removed the older requirement that a person have a one-year history of addiction before being admitted to an OTP. Telehealth flexibilities for buprenorphine, including audio-only visits in many cases, run through December 31, 2026 under a fourth temporary DEA and HHS extension, alongside a permanent buprenorphine telemedicine rule that took effect at the end of 2025. Methadone for OUD is still dispensed only through an OTP. Take-home and telehealth eligibility are decided by your program based on your stability in treatment. See ongoing methadone treatment for what longer-term care looks like.
Paying for treatment in Colorado
Health First Colorado, the state’s Medicaid program, covers all three FDA-approved medications for opioid use disorder. Methadone is covered in outpatient narcotic treatment programs under both fee-for-service and managed care; buprenorphine and Suboxone are covered as a pharmacy benefit and appear on the state Preferred Drug List, with prior authorization on some formulations (Colorado Department of Health Care Policy and Financing, 2025). Most commercial plans sold in Colorado cover buprenorphine and naltrexone; methadone coverage varies more by carrier, so confirm with the clinic and your insurer. Medicare Part B covers OTP services with cost-sharing waived after the deductible, and Part D covers self-administered buprenorphine. If you are uninsured, the state’s Behavioral Health Administration can route you to providers that accept the SAMHSA block grant and other public funding, and many OTPs offer sliding-scale fees.
Denver’s overdose picture, and why it matters for treatment
The Denver Department of Public Health and Environment reported 346 fentanyl-involved deaths in 2025, up from 277 in 2024, the second highest annual total in the past five years (DDPHE preliminary data, 2026). Methamphetamine-involved deaths also rose, with most of those cases involving fentanyl as well. Statewide, fentanyl-related deaths fell about 28 percent over the most recent CDC reporting period, which makes the Denver figures a clear local exception (CDC; Colorado Department of Public Health and Environment, 2025). The Denver Office of the Medical Examiner has also noted fentanyl showing up more often as powder rather than counterfeit pills, which raises the risk of unintentional exposure for people who think they are using something else. None of this changes what works clinically. Medication treatment substantially lowers overdose mortality, and starting it sooner matters more than starting it perfectly. More on opioid use disorder.
Overdose prevention and harm reduction in Denver
Denver has one of the most developed harm reduction networks in the Mountain West, and it works alongside medical treatment rather than in place of it. Three syringe access programs operate in the city: the Harm Reduction Action Center at 112 East 8th Avenue, Access Point at Colorado Health Network, and Vivent Health’s Lifepoint mobile unit. All three distribute naloxone, fentanyl test strips, safer use supplies, and referrals to medication treatment, and combined they served thousands of unique participants in recent years (Denver Syringe Access Program Needs Assessment, 2023).
Naloxone (Narcan) reverses an opioid overdose within minutes. In Colorado, anyone can pick it up at participating pharmacies without a personal prescription under a statewide standing order issued by CDPHE’s chief medical officer (SB 15-053). The Stop the Clock Colorado pharmacy finder lists participating locations. Health First Colorado covers naloxone without prior authorization, and the CDPHE Opioid Antagonist Bulk Purchase Fund supplies it free to eligible community agencies, including all Colorado methadone programs. Colorado’s 911 Good Samaritan Law (C.R.S. §18-1-711) protects both the person calling for help and the person experiencing the overdose from prosecution for certain possession offenses, and C.R.S. §18-1-712 protects anyone administering naloxone in good faith. See methadone overdose and what to watch for if you or someone you care about is starting or in treatment.
Treatment during pregnancy and for people experiencing homelessness
Two situations carry particular weight in Denver and warrant a closer look.
Pregnancy and the perinatal period. Both methadone and buprenorphine are recommended treatment for opioid use disorder during pregnancy. Untreated OUD carries higher risks for the pregnancy than medication does, and Colorado law explicitly protects this care: HB12-1100 and HB19-1193 prevent drug screens, test results, and conversations about substance use obtained through prenatal or behavioral health care from being used in criminal prosecution of the pregnant person. Colorado uses a Plan of Safe Care, coordinated by the Colorado Department of Human Services Division of Child Welfare in partnership with SuPPoRT Colorado, to support the family and connect them to treatment, with the explicit aim of keeping families together rather than triggering removal. The Colorado Hospital Substance Exposed Newborns Collaborative (CHoSEN) sets standardized care practices for babies who were exposed prenatally. Methadone and pregnancy covers what the medication does and does not do during pregnancy and lactation.
People experiencing homelessness. Overdose is the leading cause of death among people experiencing homelessness in Denver, and fentanyl is involved in most of those cases (Metro Denver Homeless Initiative; The Colorado Sun, 2025). Several Denver clinics list outreach or low-barrier programs in their service descriptions, and Denver Health’s mobile and integrated programs work alongside the city’s syringe access programs to connect people to buprenorphine and methadone. If you are helping someone without stable housing, ask the clinic about same-day intake, no-ID options, and any partnership with street outreach. Information for families covers more on supporting someone through treatment.
Common questions about Denver methadone clinics and MOUD
Do I have to go to a clinic every day on methadone?
Daily dosing is typical at the start. As you stabilize, federal rules now allow OTPs to provide take-home doses on a graduated schedule, up to a 28-day supply for patients who are stable in treatment. The exact pace is decided by your program based on your progress, attendance, and clinical picture.
Can I start Suboxone by telehealth in Colorado?
In most cases yes, as of this writing. Federal flexibilities for buprenorphine telehealth, including audio-only visits where appropriate, run through December 31, 2026, and a permanent buprenorphine telemedicine rule is now in effect. Confirm current options with the provider you contact, because the rules are still being finalized.
What does it cost if I don’t have insurance?
Many Denver OTPs and office-based providers offer sliding-scale fees, and some accept the SAMHSA block grant. The Behavioral Health Administration’s OwnPath Care Directory and Colorado LIFTS can also help you find a provider that fits your budget. Ask about cost when you call.
Is methadone just trading one drug for another?
No. Methadone and buprenorphine are evidence-based medical treatments for a chronic condition. At a steady dose, methadone does not cause the highs and lows of opioid use and is associated with substantially lower overdose mortality. Reputable U.S. clinical bodies, including SAMHSA and NIDA, describe long-term medication as legitimate care, not a stopgap. See addiction, dependence, and methadone for the distinction.
What if I’m transferring from another clinic or another state?
OTPs in Denver routinely accept transfers, including guest dosing for short trips. Bring your current dose, last dosing date, and program contact information. Most clinics aim to avoid any gap in dosing.
