Learn moreWhat opioid withdrawal feels like
Timing depends on the opioid. Short-acting opioids like heroin and most painkillers follow this pattern; long-acting opioids start later and last longer.
Anxiety, sweating, yawning, runny nose, watery eyes, muscle aches and cravings.
Symptoms peak: nausea, vomiting, diarrhea, stomach cramps, chills and insomnia.
Physical symptoms fade. Sleep, appetite and energy start to recover.
Cravings, low mood and poor sleep can persist. Ongoing therapy and MAT help prevent relapse.
Overdose risk rises after detox because tolerance drops quickly. Keep naloxone (Narcan) on hand and call 911 if someone’s breathing slows or stops.

MAT for opioid use disorder
Medications for opioid use disorder are among the most effective tools available. They reduce cravings and withdrawal, and lower the risk of relapse and overdose.
Buprenorphine (Suboxone)
Eases withdrawal and cravings. Our medical team times the first dose carefully, especially after fentanyl, to avoid precipitated withdrawal.
Naltrexone
A non-opioid medication that blocks opioid effects. It is started after detox, once opioids have cleared the body.
Medication + therapy
MAT works best with counseling. Every client on MAT also takes part in individual and group therapy.

Opioid detox and rehab: common questions
Still have questions? Our admissions team answers calls 24/7. Every conversation is free and confidential.
How long does opioid detox take?
Most people complete medical detox in about 5–10 days. Short-acting opioids like heroin and most painkillers usually resolve faster than long-acting ones. Afterwards, we recommend residential or outpatient treatment to address the addiction itself.
Do you use Suboxone for opioid detox?
When it’s medically appropriate, yes. Buprenorphine (the main ingredient in Suboxone) can ease withdrawal and cravings. Our medical team decides on timing and dose after your assessment. Some clients continue it as part of ongoing medication-assisted treatment.
Is it safe to stop opioids on my own?
Opioid withdrawal is rarely fatal on its own, but it can cause dangerous dehydration, and relapse after a period without opioids carries a high risk of overdose. Supervised detox is safer and far more likely to lead to lasting recovery.
How long is opioid rehab?
After detox, many clients spend around 30 days in residential treatment, then step down to PHP or IOP. Your clinical team adjusts the plan to your progress.
Does insurance cover opioid addiction treatment?
Most PPO plans cover medically necessary detox, MAT and residential treatment. We verify your benefits for free before admission. Check your coverage or call (855) 906-4088.
