How Long Does Detox Take in San Antonio? Timelines & What to Expect

How Long Does Detox Take? Understanding Withdrawal Timelines in San Antonio

If you or someone you love is considering detox in San Antonio, one of the first questions you’re probably asking is: how long does detox take? The answer depends on the substance, how long it’s been used, your overall health, and the level of medical support you receive.

At Briarwood Detox Center, we provide outpatient detox services in San Antonio with medically supervised care designed to keep you safe, stable, and supported throughout withdrawal. While detox timelines vary, most people complete the acute withdrawal phase within 5 to 10 days — though some substances require longer monitoring.

This guide breaks down detox timelines by substance, explains what affects how long detox takes, and helps you understand what to expect during medically managed withdrawal in San Antonio.

What Is Medical Detox?

Medical detox is the process of safely removing drugs or alcohol from your body under clinical supervision. It addresses the physical withdrawal symptoms that occur when you stop using a substance your body has become dependent on.

Detox is not the same as rehab — it’s the critical first step. Learn more about the difference in our guide: Detox vs. Rehab: Which Do You Need First?

Medically supervised detox includes:

• 24/7 monitoring by licensed medical staff (in inpatient settings) or scheduled clinical check-ins (outpatient)
• Medications to reduce cravings, prevent complications, and ease discomfort
• Vital sign tracking and symptom management
• Connection to ongoing treatment after detox is complete

The length of detox depends heavily on the substance involved and individual factors like metabolism, co-occurring health conditions, and history of use.

How Long Does Alcohol Detox Take?

Typical timeline: 5–7 days for acute withdrawal; up to 2 weeks for full stabilization

Alcohol withdrawal can be dangerous without medical supervision. Symptoms usually begin within 6 to 12 hours after the last drink and peak around 24 to 72 hours. Severe symptoms — including seizures and delirium tremens (DTs) — can occur during this window, which is why medical detox is essential for heavy or long-term drinkers.

Alcohol detox timeline:

• 6–12 hours: Anxiety, nausea, tremors, sweating
• 12–24 hours: Increased heart rate, confusion, irritability
• 24–72 hours: Peak symptoms — seizures, hallucinations, DTs (in severe cases)
• 5–7 days: Most acute symptoms resolve with medical support
• Weeks to months: Post-acute withdrawal symptoms (PAWS) like mood swings, sleep issues, and cravings may persist

Briarwood’s medically supervised alcohol detox uses FDA-approved medications like benzodiazepines to prevent seizures and manage symptoms safely. Our San Antonio outpatient detox program allows you to detox with professional support while maintaining daily responsibilities.

How Long Does Opioid Detox Take?

Typical timeline: 5–10 days for acute withdrawal; longer for medication-assisted treatment (MAT) stabilization

Opioid withdrawal is intensely uncomfortable but rarely life-threatening. The timeline depends on whether the opioid is short-acting (heroin, oxycodone) or long-acting (methadone, fentanyl).

Short-acting opioids (heroin, oxycodone, hydrocodone):

• 6–12 hours: Symptoms begin (muscle aches, anxiety, sweating)
• 1–3 days: Peak symptoms (nausea, vomiting, diarrhea, severe cravings)
• 5–7 days: Acute symptoms subside

Long-acting opioids (methadone, fentanyl):

• 12–48 hours: Symptoms begin
• 3–5 days: Peak intensity
• 10–14 days: Acute phase resolves

At Briarwood, we use medications like buprenorphine (Suboxone) and clonidine to manage cravings, reduce discomfort, and support safe withdrawal. Our team connects you with medication-assisted treatment (MAT) options for long-term recovery after detox.

How Long Does Benzodiazepine Detox Take?

Typical timeline: 2–8 weeks, depending on the medication and taper schedule

Benzodiazepines (Xanax, Ativan, Valium, Klonopin) require a slow, medically supervised taper to prevent seizures and other dangerous complications. Abruptly stopping benzos can be life-threatening.

Benzo detox timeline:

• 1–4 days: Early symptoms (anxiety, insomnia, agitation)
• 5–14 days: Peak withdrawal (tremors, increased heart rate, confusion, risk of seizures)
• 2–8 weeks: Gradual taper under medical supervision
• Months: Protracted withdrawal symptoms (PAWS) — anxiety, cognitive issues, sleep disturbances

Briarwood’s approach to benzodiazepine detox includes careful medication management and symptom monitoring to ensure safety throughout the taper process.

How Long Does Stimulant Detox Take?

Typical timeline: 3–7 days for acute symptoms; weeks for mood and energy stabilization

Stimulants like cocaine, methamphetamine, and prescription amphetamines (Adderall, Ritalin) cause intense psychological withdrawal, though physical symptoms are less dangerous than with alcohol or benzos.

Stimulant detox timeline:

• 1–3 days: Crash phase (extreme fatigue, depression, increased appetite)
• 3–7 days: Cravings, irritability, sleep disturbances
• Weeks to months: Mood swings, anhedonia (inability to feel pleasure), cognitive fog

Medical detox for stimulants focuses on safety, hydration, nutrition, and managing co-occurring mental health conditions like depression and anxiety. Learn more: Cocaine Addiction Treatment

Factors That Affect How Long Detox Takes

Detox timelines are not one-size-fits-all. Several factors influence how long withdrawal lasts:

• Substance type: Alcohol and benzos often require longer medical supervision; opioids vary by type.
• Duration and intensity of use: Long-term, heavy use typically leads to longer, more severe withdrawal.
• Polydrug use: Using multiple substances (e.g., alcohol and benzos together) complicates detox and extends timelines.
• Age and overall health: Older adults or those with chronic conditions may need extended monitoring.
• Co-occurring mental health conditions: Depression, anxiety, PTSD, and other diagnoses can prolong withdrawal and require integrated care.
• Previous detox attempts: The kindling effect can make each subsequent withdrawal from alcohol or benzos more severe.

What Happens After Detox?

Detox addresses the physical dependence on a substance — but it’s only the beginning of recovery. Detox alone is not treatment. Without follow-up care, relapse rates are high.

After completing detox at Briarwood, we help you transition to:

• Outpatient counseling and therapy (individual, group, family)
• Medication-assisted treatment (MAT) for opioid or alcohol use disorders
• Dual diagnosis treatment for co-occurring mental health conditions
• Peer support groups and community-based recovery resources
