Medical Detox Services In Illinois

Medical detox is the first step in substance use disorder treatment for most people with a physical dependence on alcohol, benzodiazepines, or opioids. It is also the step people fear most, usually because withdrawal has a reputation for being miserable and, for some substances, dangerous.

Illinois Recovery Center runs a licensed medical detox program at both of our locations, Swansea and Highland. Our clinicians manage withdrawal around the clock, uses medication where it helps, and moves you directly into treatment when detox is done. Here is what the program involves, who it is for, what it costs, and what happens next.

What Medical Detox Is

Medical detoxification is the process of clearing drugs or alcohol from the body under medical supervision. The goal is not just to get through withdrawal syndrome, but to get through it safely, as comfortably as possible, and in a way that sets up the treatment that follows.

At Illinois Recovery Center, detox is delivered as withdrawal management (ASAM level 3.7), which means medically monitored inpatient care with 24-hour nursing. You stay on site, a physician oversees your care, and a team of medical professionals and counselors monitors you through the acute withdrawal period.

Who Needs Medical Detox

Not everyone who stops using needs a supervised detox. The people who do are those with a physical dependence, where stopping abruptly is either dangerous or so uncomfortable that relapse is almost guaranteed. That generally means:

• Alcohol. Stopping suddenly after heavy daily drinking can cause seizures and delirium tremens, which can be fatal without treatment. Alcohol withdrawal should always be medically supervised.
• Benzodiazepines. Xanax, Klonopin, Valium, and similar medications require a gradual taper. Abrupt cessation carries a risk of seizures and psychosis.
• Opioids. Heroin, fentanyl, and prescription painkillers such as oxycodone. Withdrawal is rarely life-threatening on its own but is intensely uncomfortable, and the loss of tolerance during detox makes a relapse far more likely to end in overdose.
• Stimulants. Cocaine and methamphetamine do not cause the same physical dependence, but the crash that follows brings severe depression and cravings. Detox is recommended when someone has been using heavily or alongside alcohol or other drugs.

If you are not sure whether you or a loved one needs alcohol detox or drug detox, the admissions assessment will tell you. No referral is needed to start; call us directly, or have your physician or therapist refer you. Nobody is placed in detox who does not need it, and nobody is sent straight to residential who does.

Two Illinois Locations

Medical detox is available at both of our treatment centers:

• Swansea (St. Clair County) serves the Metro East and greater St. Louis area with the full continuum of care: detox, residential, partial hospitalization, intensive outpatient, and outpatient treatment.
• Highland (Madison County) serves southern Illinois with medical detox and residential treatment.

Because detox and residential care are on the same campus at both locations, you move from one to the other without changing facilities, care teams, or treatment plans.

What to Expect in Our Detox Program

Admission and Assessment

Detox begins with a medical and psychiatric assessment. The nursing team reviews what you have been using, how much, and for how long, along with your medical history, current medications, and any mental health concerns. This determines your withdrawal risk, which symptoms of withdrawal to expect, whether medication is needed, and what level of care you step into afterward.

24-Hour Medical Supervision

Once admitted, you receive medical care around the clock. Nurses track vital signs, watch for complications, and adjust your care as withdrawal progresses. Counselors are available throughout, because the emotional side of withdrawal is often harder than the physical side.

Medications Used in Detox

Medication is used where it makes withdrawal safer or more tolerable. Depending on the substance and your assessment, that may include:

• Buprenorphine (including Suboxone, which combines it with naloxone) for moderate to severe opioid withdrawal
• Methadone to reduce opioid cravings and withdrawal symptoms
• Naltrexone to block the effects of opioids once withdrawal is complete
• Clonidine for sweating, cramps, insomnia, tremors, anxiety, and nausea
• Acamprosate to help restore the brain’s chemical balance after alcohol
• Phenobarbital to prevent seizures during alcohol withdrawal

Medication-assisted treatment (MAT) started during detox can continue through residential and outpatient care for clients recovering from opioid or alcohol use disorder.

How Long Detox Takes

The timeline depends on the substance, how long and how heavily you have been using, your age, and your overall health. Typical ranges:

Substance	Typical detox length	Notes
Alcohol	3 to 7 days	Symptoms peak at 24 to 72 hours; seizure risk is highest in this window
Opioids	5 to 10 days	Fentanyl withdrawal can run longer than heroin or prescription opioids
Benzodiazepines	1 to 4 weeks	Managed as a gradual taper rather than a stop
Stimulants	3 to 7 days	Acute crash resolves in days; mood and cravings take longer

Most clients complete the detox process in under a week before stepping down to residential treatment.

What Happens After Detox

Detox gets the substance out of your system. It does not address the reasons you were using or teach you how to stay stopped, which is why detox alone has a high relapse rate. At Illinois Recovery Center, detox is the entry point to a full treatment program, not a standalone service. The recovery process continues through residential and outpatient programs built around the same evidence-based care.

• Residential treatment follows detox at both locations. You live on campus with structured days of individual therapy, group therapy, and relapse prevention work.
• Partial hospitalization (PHP) and intensive outpatient (IOP) at Swansea let you step down gradually as you stabilize, with full-day or multi-day-per-week programming while you live off site.
• Outpatient care and telehealth keep you connected to your counselor once you are back at work and home.
• Sober living is available for clients who need a structured, substance-free place to live during the transition.

Co-occurring Mental Health Conditions

Most people arriving for detox are also dealing with depression, anxiety, PTSD, or another mental health condition. Our dual diagnosis programming treats both together from the start. The clinical approach is trauma-informed, and therapy draws on cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and motivational interviewing, with EMDR available for clients with trauma histories.

Aftercare and Alumni Support

Aftercare planning begins well before discharge. Every client leaves with a written plan covering continuing therapy, relapse prevention, support groups (12-step, SMART Recovery, or both), and who to call when things get hard. Case management helps with the practical side, including housing, employment, and family communication. Our alumni community stays in touch through regular meetings, peer support, and follow-up from our team, so treatment ending does not mean support ending.

Cost and Insurance

Cost is the most common reason people delay detox, so we deal with it first. Illinois Recovery Center accepts most private health insurance plans, including Blue Cross Blue Shield, Aetna, Cigna, UnitedHealthcare, and Humana, as well as Medicaid. Under the Affordable Care Act, insurers are required to cover addiction treatment as an essential health benefit, so most people have more coverage than they expect.

What you pay out of pocket depends on your plan’s deductible, co-payments, and whether prior authorization is required for inpatient care. Our admissions team verifies your coverage for free before you commit to anything and handles the authorization process with your insurer. If you are uninsured or prefer not to use insurance, self-pay options are available and we will walk you through the cost of each level of care.

Our Facilities

Our Swansea campus sits on 12 acres on Caseyville Avenue, with a home-like interior designed to feel nothing like a hospital. Clients have private rooms, which matter more during detox than at any other point in treatment, along with an on-site fitness center, balanced meals, and access to holistic services such as acupuncture and meditation. Highland offers the same private, residential setting for clients in Madison County and southern Illinois.

Our Clinical Team

Detox is only as safe as the people running it. Our multidisciplinary team includes physicians, nurses, and licensed counselors with decades of combined experience in emergency medicine, hospital care, and substance abuse treatment.

• Katie Krueger, FNP-BC leads our nursing team. A board-certified family nurse practitioner with 14 years of experience in emergency medicine.
• Britany Wildermuth, LPN is an assistant director of nursing, with a background in hospital-based care.
• Alyce Enloe, LCPC is a licensed clinical professional counselor and medical assistant with more than 30 years in the field.
• Barb Laidlaw, LCPC is a licensed clinical professional counselor trained in EMDR and certified in clinical hypnotherapy.

Licensing and Accreditation

Illinois Recovery Center is licensed by the Illinois Department of Human Services as a provider of withdrawal management (level 3.7), clinically managed residential treatment (level 3.5), and intensive outpatient treatment (level 2). We are accredited by The Joint Commission for behavioral health care, which is the most rigorous accrediting body for addiction treatment providers in the United States, and we are LegitScript-certified for compliance and transparency in our admissions and marketing practices.
