People search for “24-hour detox in San Antonio” for two different reasons. Some want someone to talk to right now, at whatever hour it is. Others need medical care through the night, because withdrawal has already started or could turn dangerous. These are different needs, and they have different answers. This page explains what is open around the clock in San Antonio, what Briarwood’s San Antonio clinic does and does not do, which symptoms mean the emergency room, and where to get a bed tonight if you need one.

Is there 24-hour detox in San Antonio?

Briarwood’s San Antonio admissions line is answered 24 hours a day, but the San Antonio clinic is outpatient, with no one there overnight. For care through the night, you need an inpatient center.

“24-hour” can mean two things: a phone line answered around the clock, or medical staff on site through the night. In San Antonio, Briarwood offers the first. The line is answered in English and Spanish. The clinic itself, at 6707 W Hausman Rd, is outpatient. It is open Monday to Friday, 8:00am to 10:00pm. Nobody stays overnight, and there are no beds.

For care through the night, Briarwood runs inpatient detox in Austin and Houston. Both have medical staff on site 24 hours a day and on-site labs. The Austin center at 11711 N Lamar Blvd has 15 beds. The Houston center is at 1019 Ashland St.

Round-the-clock monitoring always means a bed. When you compare centers, ask whether a nurse is in the building at 2 a.m.

When is withdrawal an emergency?

Go to an emergency room or call 911 for a seizure, a fever, severe confusion, hallucinations, or an irregular heartbeat. That is the National Library of Medicine’s advice for alcohol withdrawal, and no detox clinic replaces it.

These are signs of severe withdrawal, including delirium tremens, which can be fatal. They need a hospital first. Detox comes after the person is stable.

The library adds a second, broader rule. Anyone who thinks they are in alcohol withdrawal, especially after drinking often and stopping recently, should contact a provider right away or go to the emergency room. Withdrawal usually starts within 8 hours of the last drink and peaks between 24 and 72 hours.

If you or someone with you is thinking about suicide, call or text 988 at any hour.

Who can detox as an outpatient in San Antonio?

Outpatient detox fits people whose withdrawal is expected to be mild or moderate, who have no history of withdrawal seizures, and who have a safe home with someone there to watch them.

The National Library of Medicine describes outpatient alcohol detox this way: daily visits to a provider until stable, medicine to ease symptoms, and someone at home keeping an eye on you. The American Society of Addiction Medicine uses the same idea. It calls it ambulatory care, meaning you sleep at home and come in for checks.

The same guideline lists what points away from outpatient care:

  • A past withdrawal seizure or delirium tremens
  • More than about eight standard drinks a day
  • Dependence on benzodiazepines or opioids on top of alcohol
  • A serious medical or psychiatric illness
  • No support at home, or an unsafe home

At Briarwood’s San Antonio clinic, licensed medical staff supervise every scheduled visit. Each visit checks vital signs and withdrawal symptoms, with medication when needed. If withdrawal is getting worse, the plan moves to inpatient care.

Does it depend on the drug?

Yes. Alcohol and benzodiazepine withdrawal can cause seizures, so the night matters most for them. Opioid and stimulant withdrawal is rarely dangerous to the body, but each carries its own risk.

Alcohol. The outpatient rules above apply. A past seizure or delirium tremens means a bed. The alcohol at home page covers the details.

Benzodiazepines. Xanax, Klonopin, Ativan and Valium should never be stopped suddenly. A slow taper with a prescriber can work as an outpatient. High doses or street pills call for inpatient care. The benzodiazepine withdrawal risks page explains why.

Opioids. The National Library of Medicine says opioid withdrawal is very uncomfortable but not life threatening. The danger comes after. Most opioid overdose deaths happen in people who have just detoxed, because tolerance drops. Keep naloxone on hand. The fentanyl detox page has more.

Stimulants. Cocaine and meth withdrawal is mostly a crash in mood and energy. The risk is depression, so the person should not be alone.

What happens if you call Briarwood at night?

A person answers, in English or Spanish. They ask what you use, how much, when you last used, about past withdrawals, your health and your insurance. Then they say which setting your answers point to.

There are three possible answers. If the symptoms above are already happening, the answer is the emergency room, because Briarwood is a detox center, not a hospital. If you need monitoring through the night, admissions can tell you whether Austin or Houston has a bed. If outpatient care fits, your first visit is at the San Antonio clinic during its hours.

Be honest about timing. A call on a Friday night means the clinic’s next opening is Monday at 8:00am. Alcohol withdrawal peaks between 24 and 72 hours, which can be the whole weekend. For anyone at real risk, the weekend answer is a bed, not a wait.

Insurance is checked during the same call, free and with no obligation to admit. You can also verify your benefits online in about two minutes.

What if you have no insurance?

Start with the state’s own entry point. For Bexar County and the surrounding region, that is the Center for Health Care Services, which runs the OSAR program for Texas Health and Human Services Region 8.

OSAR stands for Outreach, Screening, Assessment and Referral. It is where Texans start when they want substance use treatment and do not know where to begin. The only requirement is living in Texas. It screens you and refers you into state-funded programs, including withdrawal management. Texas Health and Human Services says to call your region’s OSAR for help 24 hours a day, seven days a week.

  • Region 8 OSAR, the Center for Health Care Services: 210-261-3076. Its crisis line is 800-316-9241.
  • 211 Texas, by dialing 2-1-1 or 877-541-7905, lists treatment programs alongside other public services.
  • SAMHSA’s National Helpline, 1-800-662-4357, is free, confidential, and answered 24/7 in English and Spanish. With no insurance, it refers you to state-funded programs and sliding-scale centers.

Does 24-hour detox mean detox takes 24 hours?

No. “24-hour” describes when help is available, not how long detox lasts. Withdrawal from alcohol peaks over the first three days, and some symptoms last for weeks.

The National Library of Medicine says alcohol withdrawal symptoms usually start within 8 hours of the last drink and peak by 24 to 72 hours. Opioid withdrawal starts within about 12 hours of the last heroin use, and within 30 hours of the last methadone dose. A detox stay is usually measured in days. The how long does detox take page breaks this down by drug.

Detox is also only the first step. In San Antonio, the next step is often intensive outpatient treatment, with daytime and evening groups. The at-home vs. medical detox page compares every setting side by side.
