Quick answer
Benzodiazepine withdrawal can cause seizures, so quitting abruptly is never the safe move — a supervised taper is. The SAMHSA locator lists 3 of St. Louis city's 22 programs offering benzo detoxification, with 7 more within a 30-mile drive. Call (800) 653-9376 free, or 988 in a crisis.
With benzodiazepines, the withdrawal is the danger. These drugs — Xanax, Klonopin, Ativan, Valium and their generics — change brain chemistry within weeks of steady use, and stopping them cold can trigger seizures, hallucinations, and a rebound of the very anxiety or insomnia they were prescribed for. The safe route is a gradual taper supervised by a clinician who has done this before. St. Louis has programs that do exactly that, and getting to one tonight is a phone call.
Why a supervised taper, not a hard stop
The FDA's boxed warning — the strongest warning the agency can put on a drug label — covers every benzodiazepine on the US market. It flags two facts that matter to you: dependence can develop in days to weeks even when you take the medicine exactly as prescribed, and abrupt discontinuation or a too-fast dose reduction can cause withdrawal reactions including seizures. Some symptoms linger for months after the last dose.
A taper is not one-size-fits-all. Dose, duration of use, and whether alcohol or opioids are also in the picture all change the schedule, which is why a program with a physician setting the pace matters more than one that simply hands you a printed schedule.
What exists in St. Louis city
Per the SAMHSA treatment locator, 22 substance use programs operate within St. Louis city limits — an independent city with its own health department — and 56 more sit within a 30-mile drive, including facilities in Clayton, Florissant, and across the river in Belleville, Illinois:
- 3 city programs list benzodiazepine detoxification among their services, alongside alcohol and opioid detox; 7 more benzo-detox-capable programs fall inside the 30-mile radius
- 14 programs citywide offer buprenorphine maintenance and 3 offer methadone maintenance, which matters if benzo dependence is tangled up with opioid use — a combination that sharply raises overdose risk and needs coordinated care
- Outpatient capacity is deep — every city program offers some outpatient level of care, and 19 run intensive outpatient (IOP), so a slow outpatient taper is realistic here rather than rare
When you call a program, ask two direct questions: Do you detox benzodiazepines specifically, not just opioids or alcohol? and Is the taper schedule set by a physician? Detox units built for other substances sometimes taper benzos far too quickly, which is precisely what the FDA warning warns against.
What the local data shows
Provisional CDC counts recorded 174 drug overdose deaths among St. Louis city residents in the 12 months ending March 2026, on federal data through early October 2026 and still subject to revision. Statewide, the UMSL-MIMH Addiction Science Team's report for Missouri DHSS counted 1,450 overdose deaths in 2024 — a 26% drop from 2023 — with more than half of all deaths involving a stimulant and roughly a third involving opioids and stimulants together. Polydrug deaths are the norm, not the exception, which is why intake staff will ask about everything you take, including pills sold on the street as Xanax. The DEA has reported that 5 of every 10 counterfeit pills it seizes contain a potentially lethal dose of fentanyl.

Frequently asked questions
Where can I detox from benzodiazepines in St. Louis?
The SAMHSA locator lists 3 of the 22 substance use programs in St. Louis city as offering benzodiazepine detoxification, and 10 within a 30-mile radius including Illinois-side suburbs like Belleville. Several of the city's detox-capable programs also handle alcohol and opioid withdrawal, so ask specifically about benzodiazepine experience when you call.
Is benzodiazepine withdrawal really dangerous?
Yes. The FDA's boxed warning for the entire benzodiazepine class warns that abruptly stopping or rapidly reducing these drugs can cause withdrawal reactions including seizures, and that physical dependence can develop within days to weeks of steady use even at prescribed doses. That is why tapers are done under medical supervision.
