Just because they call it a crisis doesn't mean treating it has to feel like one.

Sparrow Therapy System, a drug free, personalized solution for opioid withdrawal relief

Safe & Effective

Every minute counts

Successfully managing withdrawal is the first and most important step to keeping your patient engaged in the recovery process. As patients contemplate and enter opioid withdrawal they are stressed, vulnerable, and in physical and emotional pain.

If you don't act quickly and adequately control their opioid withdrawal — within minutes — you risk patient relapse. 

But, what if you had an opioid withdrawal treatment option that was easy, safe and effective. And, what if it could provide significant symptom relief in as little as 30 minutes?

FDA-Cleared, Clinically Proven Results

The Sparrow Therapy System is the first and only FDA-cleared device for opioid withdrawal supported by evidence from a Level 1, double-blinded, randomized controlled clinical trial targeting patients with opioid use disorder.

Here's what we discovered in the first 26 patients suffering from opioid withdrawal symptoms with a Clinical Opiate Withdrawal Scale (COWS) score >15:

89% of participants experienced mild to no withdrawal symptoms at 60 minutes of therapy.

By day two, 100% of participants sustained a clinically meaningful reduction of opioid withdrawal symptoms.*

93% of participants who completed detox with the Sparrow Therapy System accepted a referral to continue treatment.

*15% or greater reduction in COWS is considered clinically meaningful. Data on file.
