About the Quell device

How is Quell different from other TENS devices?

Quell is designed specifically to provide widespread relief from chronic pain. Quell’s clinically proven intensive nerve stimulation technology is 5x more powerful than other leading over-the-counter pain relief devices. Quell’s OptiTherapy® customizes and automatically adjusts therapy so that you receive optimal pain relief.

Is it covered by my health insurance?

As Quell is FDA cleared for sale without a prescription, most insurance companies will not cover the cost directly, but you may apply the cost toward your Flexible Spending Account (FSA) or Health Savings Account (HSA).

Do I need a Quell device for each leg?

No. Quell’s prescription strength therapy stimulates the sensory nerves in your leg, which then send a sensory nerve signal up to your brain. This signal in the brain releases endogenous opioids into the spine, which provide widespread relief from chronic pain. Therefore, Quell provides widespread pain relief.

Using Quell

Does it matter if I put the device on upside down?

Technically, the device will still work, but the optimal placement is on the calf, 1-2 inches below the knee, with the lights facing up so you can see them.

What does the stimulation feel like?

During therapy, the stimulation feels like a strong but comfortable tingling sensation. You are in control and can adjust the intensity as needed.

How long is a therapy session?

Sixty minutes. You may stop it manually at any time by pushing the button on the device four times quickly. You can also start and stop therapy using the Quell app.

How often can I use the device?

You may use it as often as needed for pain relief (even 24 hours a day). We recommend using your Quell for at least 2-3 full hour therapy sessions per day for the first several weeks to ensure you give Quell enough time to work.

How quickly will I get pain relief?

While it can vary, you may experience pain relief as early as 15 minutes after the start of a therapy session. However, it may take several weeks to realize the pain relief benefits of Quell.

Does the pain relief last beyond the end of a therapy session?

Yes. Pain relief may last up to an additional 60 minutes.

Can I use it with pain medication?

Yes, Quell is safe to use with your pain medication. However, we recommend letting your doctor know you are using Quell so he or she can develop the right pain management program for you.

Can I use Quell while I’m pregnant?

Quell can be used by pregnant women as long as it is placed as instructed on the upper calf. If you have any questions, please consult your doctor.

Who should not use Quell?

Quell is contraindicated if you have a cardiac pacemaker, implanted defibrillator, or other implanted metallic or electronic device. If any of these apply to you, please talk with your doctor before using the device.

Can I use Quell for headaches or migraines?

Quell is not likely to treat headaches or migraines successfully, as they occur in an area of the brain other than the area that Quell targets to treat chronic pain.

Are there side effects?

No, but some people may experience mild skin irritation under the electrodes after prolonged use.

What does it mean when the therapy stops and the light is blinking orange continuously?

A blinking orange light typically indicates poor contact between the electrode and the skin. This may occur because the device is not securely placed on the leg or has unsnapped, or because the electrode is dry. Check that the electrode is snapped into the back of the device, the electrode is in complete contact with the skin, and the band is attached snugly (but not too tightly) on the leg. Start therapy again. If the problem persists, you can either try replacing the electrode or call Customer Care at 800.204.6577.

About the app

Do I need the iOS or Android app to operate Quell?

No, Quell will function without the app. However, the app allows you to easily and discreetly control therapy from your smartphone, and track your therapy and sleep.

Is there any cost for the app?

No, the app may be downloaded for free from the Apple or Android app stores.
