Facing the 800-pound Gorilla of Withdrawal

Deciding to reduce or eliminate opioids from daily life isn’t easy. Taking that first step away from opioids and toward the certainty of withdrawal can feel as if there’s an 800-pound gorilla standing in your way — keeping you from the better quality of life you want.

If you fear withdrawal, you’re not alone. Withdrawal is a painful barrier standing before over 11 million Americans who struggle with opioid dependence or addiction. It’s such a huge roadblock that two out of every five adults who need opioid reduction or elimination simply won’t seek treatment.1

Why? They fear opioid withdrawal symptoms that include:

  • Vomiting
  • Diarrhea
  • Restlessness and insomnia
  • Fever-like symptoms
  • Chills and sweating
  • Bone pain
  • Tremor
  • Mood swings

What’s even more concerning is the longer you wait to reduce or eliminate opioids, the greater your risk for more serious complications, including:

  • Constipation  
  • Depression
  • Sexual dysfunction
  • Pain Sensitivity
  • Weakened immune system
  • Addiction
  • Respiratory failure
  • Fatal overdose

The Sparrow Therapy System includes a:

Set of daily-disposable earpieces

They deliver mild electrical stimulation to the nerves on and around the ear.

Patient Controller

It powers the earpiece and allows you to adjust the intensity to suit your personal needs.


It connects and delivers the electrical impulses from the Patient Controller to the Earpiece.
