Frequently Asked Questions

Quell device

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, with the sensory nerve signal traveling 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.

Calibration

When do I need to calibrate my device?

You must calibrate the device before the first use. You may repeat calibration if pain relief has diminished.

Do I need to calibrate the device before each therapy session?

No. Once your device is calibrated, you do not need to calibrate it again unless pain relief has lessened.

Do I need to recalibrate when I switch legs?

No.

How can I be sure that I have calibrated correctly?

If you have calibrated correctly, the stimulation during therapy should feel strong but comfortable. The stimulation intensity ramps up during the first 2 minutes of each therapy session, so it may feel light at first. If it feels too strong or if you do not feel like you are getting relief, you may want to either adjust the intensity or repeat the calibration process.

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, one to two 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?

60 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 two to three 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.

Using Quell while sleeping

Can I use it while sleeping?

Yes, you may use Quell to provide pain relief while you fall asleep and throughout the night.

How do I ensure the device doesn’t wake me up while I’m asleep?

Quell offers 3 sleep mode variations, which can be controlled from the Quell app, so you can personalize your therapy.

What does Quell do while I am sleeping?

It starts 60 minute therapy sessions every other hour throughout the night, just as it does during the day. You can choose whether you want the level of stimulation to be the same as during the day or a reduced level of stimulation at night. If you need more information, please consult Chapter 6, Overnight Therapy, in the User Manual.

What if I only want a single 60 minute therapy session when going to sleep?

You can set the sleep setting to “Bedtime Only.” If you need more information, please consult Chapter 6, Overnight Therapy, in the User Manual.

What should I do before going to sleep with my Quell on?

Make sure the device is securely and comfortably placed around your leg. Then start the first therapy session by briefly clicking the button.

Electrodes

Does it matter which way I attach the electrode? Is it possible to attach it upside down?

You can attach the electrode in either orientation. The important point is to have both snaps connected.

How often do I need to change the electrode?

Electrodes may last up to 2 weeks.

How do I know when I need to replace the electrode?

If the electrode is no longer making good contact with your skin, you may want to change the electrode. You can continue to use the electrode even if the gel pad has started to peel away, as long as all four electrode gel pads make good skin contact and therapy sensations remain comfortable.

Can I use other types of gel to extend electrode life?

We do not recommend the use of supplemental gels on the Quell electrode, as they may adversely impact performance. The Quell electrode hydrogel was designed specifically to work with the Quell system and can last up to 2 weeks.

Can I use a different manufacturer’s electrode?

The Quell electrode is the only electrode cleared by the FDA for use with the Quell device. The Quell electrode was designed to ensure optimal performance and the highest level of safety.

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 1.800.204.6577.

What are the materials or ingredients in the electrode?

The hydrogel consists primarily of water, salt glycerin and a dimethylacrylamide-based polymer matrix. The hydrogel does not contain latex, BPA or phthalates.

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.

Charging the battery

How often will I need to charge the battery?

The battery will typically last over 30 hours (or 4-7 days) of therapy. Battery life depends on your therapy intensity and frequency of use.

How long does it take to recharge the battery?

Fully recharging the battery will take 2-3 hours when connecting to a charging adaptor plugged into a wall outlet. After charging is complete, all the lights on the device will go out.

What if I see a flashing orange light when I plug my device in to charge it?

If the orange light continues to blink after the device has been plugged into the adaptor and an outlet, there is a charging issue. Please call Customer Care at 800.204.6577.
