Does iReliev Electrode Pads Made with Gel Contain Salicylate?

iReliev gel pads do not contain salicylate which is necessary for many people seeking to follow protocol consistent with Guaifenesin protocol.  Considered by many as an unapproved treatment for fibromyalgia suggested in the 1990s by R. Paul St. Amand. The protocol involves three parts: titrating the guaifenesin dosage, avoiding salicylates, and following a low-carbohydrate diet if the patient is hypoglycemic.

Will sweat prevent electrode pads from adhering?

Sweat could cause the electrode pads to lose adhesion. However, many of our customers use kinesio-tape or sweat bands to prevent sweat from being saturated into the electrode pads.

Consider taping around the mini tens to prevent sweat from dripping into the electrode pad area of your body when applied.

Do you ship internationally?

Yes, we ship internationally.

Can I use iReliev if I have a pacemaker?

No. iReliev should not be used if you have a pacemaker, defibrillator, or any implanted electronic device. Also, iReliev should not be used if you have any implanted medical devices containing metal.

Can I adjust the intensity?

Yes, since pain is subjective, all iReliev devices provide adjustable intensity allowing you to customize your therapy as to whatever feels comfortable for you.

What type of battery does the Mini TENS use?


Can I use iReliev in conjunction with topical pain rubs or gels?

Topical pain creams, rubs or gels can be used before or after the use of iReliev TENS and/or EMS. Please note, topical pain creams should not be applied to the site of pain immediately before applying the iReliev electrode pads. Applying topical pain rubs in combination with the iReliev electrode pads may damage the electrode pads and prevent you from experiencing optimal electrotherapy results. However, many of our customers use gel for optimal electrical dispersion. It can increase conductivity, creating a more comfortable experience while hydrating the moisture of the gel on the original pads.

How does iReliev TENS help reduce pain?

iReliev works by producing electrical pulses that block the body’s pain signal to your brain, thus the pain symptoms you feel. TENS has also been shown in clinical studies to encourage the body to release its own natural pain relieving endorphins, sometimes referred to as the body's “feel good chemical.”

Can I use iReliev while pregnant?

Do not use during pregnancy or if you think you might be pregnant.

Do iReliev products require a Doctor’s prescription (RX)?

Nope. All iReliev devices are FDA cleared over-the-counter (OTC) devices. This includes our latest PlayMakar ET-5050 system, a high output, wireless system.

How long can iReliev TENS and/or EMS be used in a day?

Therapy sessions can last 60 minutes or less. You can use iReliev for consecutive 60-minute sessions according to your pain relief needs when used in accordance with the user manual.

why i should use this device?

It's mini size portability and 60mA power for its size makes it unique and beneficial for anyone seeking pain relief.

Is it necessary to use electrode gel with this device?

No, it is not required as the electrodes are pre-gelled.

Can the intensity selections be manually adjusted during the sessions, or do you have to reset it to get it just right?

Yes, you can change it during a session. Best way to adjust to a comfort level actually.
