Medical detox for codeine, lean, and purple drank, with medical provider-led Suboxone protocols and 24/7 nursing throughout.
Radix Recovery provides medically supervised codeine addiction treatment in Cedar Rapids, Iowa, with 24/7 nursing, medical provider-led Suboxone protocols during withdrawal, Vivitrol support after a period of Suboxone treatment, and a direct transition into residential treatment under the same clinical team. Codeine is a prescription opioid, and it is the active narcotic in lean and purple drank. Whether your codeine use started with a prescription cough syrup, a pain prescription, or with lean, the path off it is the same medical path, and we can typically arrange admission within 24 hours.
Codeine withdrawal can start within hours of the last dose, which is what drives most home attempts back to use.
Lean and purple drank are recreational forms of prescription codeine cough syrup, usually with promethazine added.
The liver converts codeine into morphine, so codeine addiction is one form of opioid addiction.
Suboxone during detox and stabilization, with Vivitrol considered later after a period of Suboxone treatment, are the medical tools that make stopping safer and more durable.

A simple, guided path into treatment fast
According to the National Institute on Drug Abuse (NIDA), repeated opioid use rewires the brain reward circuitry, building tolerance that demands higher doses, physical dependence that punishes any attempt to stop, and cravings that can persist long after the drug is gone.[2] Codeine addiction is one form of opioid addiction, and our full opioid treatment program covers prescription painkillers and other opioids as well.
Codeine carries a reputation as a weaker or safer opioid, and that reputation is part of the danger. Because it is found in prescription cough syrups and combination pain pills like acetaminophen with codeine, many people start using it legitimately and slide into dependence without ever buying anything illegal. Others escalate the dose to chase the same effect, which is the textbook pattern of opioid tolerance. There are two common roads into codeine addiction, and we treat both.
Codeine slows breathing. Mixing it with other depressants is how it becomes fatal.
Codeine, like all opioids, depresses respiration. The FDA warns that combining opioids with other central nervous system depressants,[3] including the promethazine in cough syrup and the alcohol people add to lean, multiplies the risk of dangerously slowed or stopped breathing. That combined depression is the main reason lean can be fatal, and it is why stopping should happen under medical supervision rather than alone.
If you or your loved one is unresponsive, breathing slowly, or cannot be woken after using codeine or lean, call 911 now. If you are still using codeine and want to stop, you do not have to do it alone or cold turkey. Call us at (319) 270-2890, and we will explain exactly what a safe, medical provider-directed detox looks like for your situation.
In the brain: Before codeine, dopamine and the brain’s own opioid signaling sit at a steady baseline. The mu-opioid receptors that regulate pain, reward, and breathing fire at normal levels.
What you feel: Nothing unusual. Pain and mood are at their ordinary set point, before any codeine enters the picture.
In the brain: Once codeine is in the body, the liver converts it into morphine, which binds the same mu-opioid receptors as stronger opioids and triggers a surge of dopamine through the reward circuitry.
What you feel: Pain relief and a wash of calm or euphoria. That morphine conversion is what produces both the relief people seek and the reward that drives misuse.
Opioid use rewires the reward circuitry. Receptors downregulate and the system turns down its own signaling, so the same dose does less.
What you feel: Tolerance. The old dose stops working, and it takes more codeine to reach the same effect, which is the textbook pattern of opioid escalation.
In the brain: The adapted system now relies on codeine just to feel normal. Between doses the receptors sit unoccupied, and the brain swings into the opposite, withdrawal state. This is also where co-occurring conditions surface, the anxiety, depression, and pain that SAMHSA notes affect millions of adults with substance use disorders.[4]
What you feel: Withdrawal and cravings within hours of the last dose. How we treat it: A dedicated 24/7 nursing team with physician-directed Suboxone protocols and integrated dual diagnosis care, all under one roof, so the misery that pulls home attempts back to use is managed safely.
Lean, also called purple drank, sizzurp, or simply syrup, is a recreational drink made by mixing prescription codeine cough syrup with a soft drink, often a lemon-lime soda, and sometimes hard candy. Most codeine cough syrups used for lean also contain promethazine, an antihistamine that adds heavy sedation. The U.S. Drug Enforcement Administration (DEA) identifies promethazine with codeine cough syrup as a controlled prescription product that is widely diverted for this exact purpose. The drink is the reason demand for codeine cough syrup persists well beyond legitimate medical need.
Lean became culturally visible through hip-hop and music culture starting in the 1990s, and that visibility has helped normalize it among young people who may not realize they are drinking a powerful opioid combination. The cultural framing as a casual party drink hides a serious medical truth: lean is a polysubstance opioid product, and the way it is consumed makes it dangerous.
Codeine, like all opioids, slows breathing. The FDA warns that combining codeine with promethazine, and the alcohol or other depressants people often add to lean, multiplies the risk of dangerously slowed or stopped breathing. This combined central nervous system depression is the main reason lean can be fatal.
Because lean is sipped over hours and tastes like soda, it is easy to drink far more codeine than a therapeutic dose without noticing. There is no fixed recipe, so potency varies from cup to cup, and a casual sip can carry a heavy opioid load.
Lean is frequently combined with alcohol, soda, and sometimes other drugs. Each added depressant raises the danger and complicates withdrawal, which is why supervised, medically monitored detox matters for lean specifically.
No matter how it is framed culturally, lean addiction is codeine addiction, which is opioid addiction. The withdrawal, the cravings, and the treatment are the same as for any opioid use disorder.
Whether it started with a cough syrup prescription or with lean, what happened to your brain is the same opioid pharmacology. That is not a character flaw, and it is treatable. Our job is to get you through withdrawal safely and keep you safe afterward.
Chief Clinical Officer, Radix Recovery
Codeine withdrawal follows the classic opioid pattern. It is rarely life-threatening on its own, but it is intensely uncomfortable, and the misery is what drives most home attempts back to use within days. Because lean usually contains promethazine and is often mixed with alcohol, people who stop lean can have a more complicated withdrawal than codeine alone, which is one more reason to detox under medical supervision. Our medical team adjusts your protocol to what your body actually shows us, not just the calendar.
Anxiety, restlessness, cravings, watery eyes, runny nose, yawning, sweating, and muscle aches begin. This is the window when an unsupervised quit attempt is most likely to reverse, because using again makes it all stop instantly.
Nausea, vomiting, diarrhea, abdominal cramps, chills and gooseflesh, bone and muscle pain, insomnia, and overwhelming cravings reach maximum intensity. At Radix this happens under 24/7 nursing, with Suboxone and comfort medications keeping the symptoms managed.
The worst physical symptoms fade, appetite and sleep slowly return, and the psychological work begins. This is when therapy, group work, and planning for ongoing care move to the center of treatment.
Protracted insomnia, anxiety, low mood, fatigue, and waves of craving can surface for weeks to months. This is the phase that ongoing therapy and, after a period of Suboxone treatment, Vivitrol are built to carry you through, which is why detox is a beginning rather than the whole treatment.
Stopping codeine or lean cold turkey at home rarely works, because the withdrawal arrives fast and using again makes it stop instantly. Here is exactly what the safe path looks like, from your first call to your first night at our Cedar Rapids facility.
Call (319) 270-2890. A real member of our admissions team answers 24/7, completes a brief confidential screening, and verifies your insurance, usually in under an hour.
On arrival, our medical team completes a full assessment of your use history, including codeine, promethazine, and any alcohol or other substances, withdrawal severity, and co-occurring mental health screening, with lab work.
Once withdrawal is established, our physicians begin Suboxone induction, timed to avoid precipitated withdrawal, plus comfort medications for nausea, sleep, and anxiety.
Your first night is about safety and relief. Our nursing team is available 24/7, obtains vital signs per withdrawal protocol and as needed, and adjusts your protocol so withdrawal stays managed.
Medication-assisted treatment (MAT) is the evidence-based standard of care for opioid use disorder, whether the opioid is codeine, the codeine in lean, or anything else. SAMHSA and NIDA both report that 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 for codeine is built on two medications: Suboxone during detox and stabilization, and Vivitrol for relapse prevention after a documented period of Suboxone treatment.
Codeine detox is the first step, not the whole journey. Our entire continuum runs with one clinical team that already knows your story by the time you step down, so the move from detox into residential and outpatient care happens without starting over in Cedar Rapids.
All six levels of care one campus in Cedar Rapids, one clinical team.

Yes. Codeine is an opioid, and the National Institute on Drug Abuse (NIDA) explains that repeated opioid use rewires the brain reward circuitry, building tolerance, physical dependence, and cravings. The liver converts codeine into morphine, which acts on the same opioid receptors as stronger opioids. Codeine’s reputation as a weaker or safer opioid is part of the danger, because many people slide into dependence from a legitimate cough or pain prescription without ever buying anything illegal.
Yes. Codeine is a prescription opioid. The U.S. Food and Drug Administration (FDA) classifies it as a controlled narcotic used to treat mild to moderate pain and, in some products, to suppress coughing. In the body, codeine is converted by the liver into morphine, which binds to the same opioid receptors that regulate pain, reward, and breathing. Codeine sits in the same drug class as hydrocodone, oxycodone, and morphine, so codeine addiction is one form of opioid addiction.
Lean, also called purple drank, sizzurp, or syrup, is a recreational drink made by mixing prescription codeine cough syrup with a soft drink, often a lemon-lime soda. Most codeine cough syrups used for lean also contain promethazine, an antihistamine that adds heavy sedation, and people often add alcohol or other depressants. The U.S. Drug Enforcement Administration (DEA) identifies promethazine with codeine cough syrup as a controlled prescription product that is widely diverted for this purpose. Lean is a powerful opioid combination, not a casual party drink.
Promethazine itself is an antihistamine, not an opioid, but the cough syrup commonly used for lean is a combination product of promethazine with codeine. In that product the codeine is the opioid, and the promethazine adds sedation. The FDA warns that combining codeine with promethazine, and the alcohol people often add, multiplies the risk of dangerously slowed or stopped breathing. So a promethazine-codeine product does contain codeine, and that is what makes it addictive and dangerous.
Lean is dangerous because it combines depressants that each slow breathing. Codeine, like all opioids, depresses respiration, and the FDA warns that adding promethazine and the alcohol people often mix in multiplies the risk of dangerously slowed or stopped breathing. Because lean is sipped over hours and tastes like soda, it is easy to drink far more codeine than a therapeutic dose without noticing, and there is no fixed recipe, so potency varies. No matter how it is framed culturally, lean addiction is codeine addiction, which is opioid addiction.
Codeine withdrawal follows the classic opioid pattern. Early symptoms include anxiety, restlessness, cravings, watery eyes, runny nose, yawning, sweating, and muscle aches. As it peaks, people experience nausea, vomiting, diarrhea, abdominal cramps, chills and gooseflesh, bone and muscle pain, and insomnia. It is rarely life-threatening on its own, but it is intensely uncomfortable, and that misery is what drives most home attempts back to use within days. Medical detox manages the symptoms so you can get through them safely.
Codeine withdrawal usually begins 8 to 24 hours after the last dose, peaks over days 1 to 3, and the worst physical symptoms subside over days 4 to 7. After the acute phase, some people experience post-acute withdrawal, with protracted insomnia, anxiety, low mood, fatigue, and waves of craving that can last weeks to months. Because lean usually contains promethazine and is often mixed with alcohol, stopping lean can be more complicated than codeine alone, which is one more reason to detox under medical supervision.
Codeine addiction is treated with medical detox followed by ongoing treatment. SAMHSA and NIDA report that combining FDA-approved medications with counseling significantly improves retention and reduces opioid use and overdose risk compared with abstinence-only approaches. At Radix Recovery, our medical providers use Suboxone during detox and stabilization to relieve withdrawal and cravings, comfort medications for symptoms, and Vivitrol for relapse prevention after a period of Suboxone treatment, all alongside therapy and dual diagnosis care under one clinical team in Cedar Rapids.
