Heroin reaches the brain within seconds of use, converts to morphine, and binds to opioid receptors that regulate pain, reward, and breathing. The surge of dopamine it triggers teaches the brain to prioritize heroin above food, relationships, and safety.
According to the National Institute on Drug Abuse (NIDA), repeated heroin use physically changes the brain, creating tolerance that demands higher doses, dependence that punishes any attempt to stop, and cravings that persist long after the drug is gone. That is why willpower alone fails so often. Heroin addiction is a chronic medical condition, and it responds to medical treatment.[1]
Our approach pairs FDA-approved medications with around-the-clock clinical care, then carries you directly into therapy that addresses why you started using in the first place. Heroin addiction is one form of opioid addiction, and our full opioid treatment program covers prescription painkillers and synthetic opioids as well.

Heroin withdrawal is one of the main reasons people keep using even when they desperately want to stop. It is rarely life-threatening on its own, but it is intensely uncomfortable, and complications like dehydration from vomiting and diarrhea can become medical emergencies. Because fentanyl now dominates the supply and clears the body more slowly, many people experience a delayed onset and a longer, harsher course than the classic heroin timeline below. Our medical team adjusts your protocol to what your body actually shows us, not just the calendar.
Anxiety, restlessness, drug cravings, muscle aches, watery eyes, runny nose, yawning, and sweating start within 6 to 12 hours of the last dose. This is the window when most home detox attempts fail, because using again makes everything stop instantly. In our care, this is when Suboxone induction typically begins, once withdrawal is clearly established.
Symptoms reach maximum intensity: nausea, vomiting, diarrhea, abdominal cramping, chills and gooseflesh, bone and muscle pain, insomnia, elevated heart rate and blood pressure, and overwhelming cravings. Our nursing team monitors you around the clock, manages hydration, and titrates medications so the peak stays tolerable.
The worst physical symptoms taper off. Appetite begins to return, sleep slowly improves, and energy comes back in stretches. This is also when the psychological work begins: cravings remain strong, and the temptation to leave treatment early peaks. Moving directly into residential care at this stage protects the progress you just fought for.
After acute detox, many people experience protracted symptoms: insomnia, anxiety, irritability, low mood, fatigue, difficulty concentrating, and intermittent waves of craving. These post-acute withdrawal symptoms are a normal part of the brain healing, and they are a major relapse driver when faced alone. Ongoing therapy, structure, and medication support like Suboxone or naltrexone carry you through this phase.

Medication-assisted treatment (MAT) is the evidence-based standard of care for opioid use disorder. Combining FDA-approved medications with counseling significantly improves treatment retention and reduces opioid use and overdose risk compared with abstinence-only approaches. Our MAT program is built on several medications, two of which include: Suboxone for withdrawal management and stabilization, continued as maintenance when clinically appropriate, and Vivitrol (injectable naltrexone) which is a relapse-prevention option for some clients, though it is rarely started during Residential treatment because many insurance plans require documented failure of or intolerance to Suboxone before approval.

Detox alone is not treatment for heroin addiction. Medical detox manages withdrawal safely, but without continued care, most people return to use, and for opioid use disorder the agency recommends at least 90 days of treatment engagement for meaningful results. That is why our entire continuum lives under one roof in Cedar Rapids, with one clinical team that already knows you by the time you finish detox. There is no discharge gap, no referral to a stranger across town, and no week of waiting where relapse can take hold.

Heroin is one of the most addictive substances known. It crosses the blood-brain barrier within seconds, converts to morphine, and floods the brain’s reward circuitry with dopamine. According to the National Institute on Drug Abuse, repeated use changes the brain’s structure and chemistry, creating tolerance, physical dependence, and powerful cravings that can persist long after a person stops using. That is why heroin addiction is treated as a chronic medical condition, not a failure of willpower.
Acute heroin withdrawal typically begins 6 to 12 hours after the last dose, peaks between days 1 and 3, and subsides over days 4 to 7. Because most street heroin now contains fentanyl, which leaves the body more slowly, withdrawal can start later and last longer than these classic windows. Post-acute withdrawal symptoms such as insomnia, anxiety, low mood, and cravings can continue for weeks to months and are addressed in ongoing treatment.
Yes. Suboxone (buprenorphine/naloxone) is a foundation of our medication protocol for heroin detox. Our medical providers time the first dose carefully based on your withdrawal severity to avoid precipitated withdrawal, then stabilize and taper you under 24/7 nursing supervision. After detox, Vivitrol (naltrexone) is available as a monthly, non-opioid option that blocks heroin’s effects and supports long-term recovery.
We strongly advise against it. Heroin withdrawal is rarely fatal on its own, but vomiting, diarrhea, and sweating can cause severe dehydration, and the misery of withdrawal drives most home attempts back to use within days. The greater danger comes after: detox lowers your tolerance, so a return to a previous dose can cause fatal overdose, especially with fentanyl in the supply. Medically supervised detox is safer and far more likely to succeed.
Because most of it is not just heroin anymore. The CDC and DEA report that the majority of street heroin is now mixed with or replaced by illicitly manufactured fentanyl, a synthetic opioid up to 50 times stronger than heroin. Doses are unpredictable from bag to bag, which is why overdose deaths involving synthetic opioids have risen so sharply. Anyone using heroin today should assume fentanyl exposure, and treatment plans need to account for it.
Medical detox usually takes 5 to 7 days for heroin. From there, we recommend residential treatment in 30, 60, or 90-day pathways, followed by step-down care through PHP, IOP, and outpatient programming.
In most cases, yes. We are in-network with Wellmark Blue Cross Blue Shield, TriWest Healthcare Alliance, Midlands Choice, Cigna Healthcare, Health Choice, and Medical Associates, and we work with many other plans. Substance use disorder treatment is an essential health benefit under federal parity law. Call (319) 270-2890 or use our confidential insurance verification form, and our admissions team will confirm your exact coverage at no cost and with no obligation.
Recovery is common, but it usually takes sustained treatment. Relapse means treatment needs adjustment, not that recovery is impossible. People who complete detox, continue into residential and outpatient care, and use medications like Suboxone or Vivitrol have significantly better long-term outcomes than those who stop at detox alone.
We work to admit you the same day or within 24 hours whenever a bed is available, because we know the window of willingness with heroin can close fast. Call (319) 270-2890 any time, day or night. Our admissions team will complete a phone screening, verify your insurance, and coordinate your arrival at our Cedar Rapids facility, including travel guidance for families coming from across Iowa.Yes.
Detox clears heroin from your body, but it does not treat the addiction itself. After detox, most of our residents step directly into residential treatment at our Cedar Rapids facility, where the same clinical team continues your care with individual therapy, group work, dual diagnosis treatment, and Vivitrol if appropriate. From residential, you can step down to PHP, IOP, and outpatient care while staying connected to our alumni community.
IOP at Radix means keeping your job, your family, your life while getting the real clinical support that makes lasting recovery possible. Start as soon as tomorrow.
