Back To Basics

How Does It Work? 

Monthli is the first completely wireless transcutaneous electrical nerve stimulation machine (or TENS for short) with heating capabilities. Monthli is designed to help women relieve pain caused by primary menstrual pain (dysmenorrhoea) or secondary menstrual pain caused by conditions such as endometriosis, adenomyosis, uterine fibroids, pelvic inflammatory disease (PID) or polycystic ovary syndrome (PCOS). 

It works by sending soothing pulses through the skin and along the nerve fibers where pain originates. These pulses suppress menstrual pain signals to the brain and encourage your body to produce elevated levels of its own natural pain killing chemicals such as endorphins and encephalins.  

Does Monthli Completely Cure Period Pain?

As a completely female run company we don’t believe it’s fair to advertise our product in a way that isn’t accurate. We also know that every woman experiences period pain differently, and everyone has their own ways of dealing with it (god knows we’ve tried them all). We believe Monthli is a very effective addition to your arsenal of treatments against period pain as a natural, non-evasive, and drug free option.  

What Makes Monthli Different From Other Pulse Therapy Machines? 

Monthli isn’t just a pretty piece of technology, it’s one of a kind. We’ve studied other pulse therapy machines on the market and have made key changes to improve its versatility and convenience.  

Monthli is completely wireless, think of it as upgrading from your old Apple earbuds that would get tangled and wear out over time to a beautiful new pair of Air Pods. The future is wireless, but it’s also long lasting – Monthli's internal battery when fully charged via micro USB will last you up to 20 hours of use! If that wasn’t enough, we’ve also included 5 types, and 20 different levels of massage pulse therapy for you to choose from.  

We’re not done a little icing on top we’ve added a fast-acting hot pack option with 3 additional levels to choose from using the latest in far infrared graphene heating technology. By fast-acting we mean FAST - in just 5 seconds you will feel a wave of warmth emanate from Monthli to relieve your menstrual pain almost instantly.  

What Does It Feel Like? 

Our customers have described Monthli as feeling like a gentle pulsing or vibrating massage! When used in combination with the hot pack function, Monthli feels like a warm cloud floating above your skin, sounds nice doesn’t it?  

How Long Does It Take To Feel The Effects of Monthli?  

Based off customer feedback many begin to feel relief within seconds! If you don’t feel relief within 15 minutes of use, we recommend adjusting the placement of Monthli on your body as well as the intensity level being used by pressing the plus and minus buttons on the sides of your device.   

Insider Tip: Identify the origin of your menstrual pain on your abdominal or lower back area and place Monthli directly on top of this area. Increase the intensity level gradually until you begin to feel relief.  

Will Monthli Help With Severe Menstrual Cramps Or Extremely Painful Periods? 

Absolutely! Monthli helps to relieve pain from even the most severe conditions such as endometriosis, pelvic inflammatory disease, PCOS, fibroids and adenomysois. Depending on your condition we recommend you consult with your physician to see if Monthli is right for you!  

Is Monthli Safe To Use?  

You bet! TENS therapy has been used for decades to treat body pains, and is medically tested and proven to be a safe and effective way to relieve menstrual pain. 

Are There Any Side Effects?  

No! We’re proud to offer our customers an effective, drug-free option for menstrual pain relief without any side effects. 

Can I Use Monthli On Other Parts of My Body? 

While we recommend using Monthli for period pain occurring on the abdomen or lower back, you can also use it on your shoulders, back, arms, legs and along your waist to relieve muscle pain. Do not use Monthli anywhere on your head, neck, chest or private area.  

Can I Still Be Active While Wearing Monthli?  

Definitely! Trust, we know periods suck, but we encourage our users to stay active and wear our device whether you’re at home, at work, commuting, out for a walk! Full disclosure, we don’t recommend using Monthli while performing high intensity cardio exercise or in hot environments such as a hot yoga studio as the accumulation of sweat will impact the conductivity of the gel pads and performance of the device. 

Is Monthli Suitable For Teenage Girls Experiencing Their Menstrual Cramps For the First Time?  

One hundred percent! Monthli is completely safe for anyone experiencing menstrual cramps above the age of 12. It is easy to learn and discreet to use, even when you’re at school. 

Will My Fertility Be Affected By Using Monthli?  

No, absolutely not. Monthli does not interfere with your hormonal balance, cycle or other bodily functions. However, we do not recommend using Monthli if you’re currently undergoing fertility treatment.  

Are There Any Health Restrictions That Would Prevent Me From Using Monthli?  

Our product should never be used by anyone wearing a pacemaker or any other medical electrical implant device. Do not use Monthli if you have severe cardiac arrhythmia, angina or heart failure. This device is not suitable for women undergoing pregnancy or children under 12 years of age. Please consult your physician before using Monthli if you are on any medication, have any infectious disease, are experiencing fever, or suffer from acute/purulent inflammation. Monthli should not be used by those who have fragile or very thin skin, hemophiliac bleeding tendencies, blood pressure disorders or skin allergies. 

I Already Take Medication For My Menstrual Pain, Is It Safe To Use Both At The Same Time?  

While Monthli is completely safe to use while taking commercially available pain killers such as ibuprofen (Advil), paracetamol (Tylenol), or naproxen (Aleve), we recommend consulting a physician before using Monthli if you are taking any other prescribed medications. 

Can Other People Tell When I’m Using Monthli?  

No! We’ve designed our product to be easily concealed under any outfit while also offering an appealing cloud-like silhouette design that many of our customers don’t even mind showing off! In fact, we love when customers send us photos of them using Monthli, whenever and wherever they are! Make sure to tag us @lovemonthli and use the hashtag #LoveMonthli  

I Have An IUD, Is It Still Safe For Me To Use Monthli?  

Yes! Monthli is safe to use with both copper and hormonal IUDs. If you’re unsure we always advise our customers to ask their doctor if Monthli is right for them. 

I’m A Bit Curvier Than Most Women, Will Monthli Still Work For Me?  

Absolutely! We here at Monthli believe all women no matter their body-type deserve the best drug free pain relief money can buy! 

Can I Wear My Monthli Over My Clothing?  

Great question! While we would love for that to be possible, our gel pad needs to be in direct contact with your skin for our pulse therapy to function properly.  

Can I Wear My Monthli To Bed?  

Like any other TENS machines, you should always be fully awake, conscious and of sound mind when using Monthli. Under no circumstances should you wear it to bed! 

Technically Speaking...

How Often Do I Need To Order Replacement Gel Pads? 

Our high-grade gel pads can be used between 30-50 times! Depending on your level of usage, we advise our customers to replace their Gel Pads Monthly 😉. As a rule of thumb, the more care you put into keeping your gel pads clean and dust free, the longer they will last!  

How Long Does It Take To Charge My Monthli? 

Monthli charges in just 2 hours for 20 hours of period pain relief in TENS mode! The red indicator light next to the charging port indicates that your device is charging, and it is fully charged when the indicator light turns off!

Devices purchased before December 15th, 2022: When fully charged, the indicator light will turn BLUE.

Devices purchased on or after December 16th, 2022: When fully charged, the indicator light will turn OFF.

Does Monthli Require Batteries?  

No! That’s the beauty of it, Monthli is built with a long-lasting internal battery (500 mAh), that can be easily charged via the micro USB provided in each box. Oh, and need we remind’s completely wireless! 

How Long Does The Battery Last? 

When fully charged our battery lasts for 20 hours when using the TENS pulse therapy option, and 1 hour when using the fast-acting hot pack option! To prevent muscle fatigue, skin tingling and redness we recommend using Monthli for no more than 30 minutes at a time.

How Long Should I Use My Monthli For? 

Monthli comes equipped with an automatic timer so that the device will turn off after 30 minutes of use. It is recommended to use Monthli for no more than 30 minutes at a time in one spot to prevent muscle fatigue, skin tingling, and redness. If you still experience cramps after 30 minutes of use, reposition your device to a different area on your skin near the origin of your pain.  

Can I Use My Monthli While It’s Charging? 

As tempting as that sounds, we do not recommend you use our device while it’s charging – but don’t fret, it only takes 2 hours to fully charge Monthli and you can enjoy 20 hours worth of pain relief as soon as that little indicator light turns off! Trust us when we say, it’s worth the wait.  

What Is Far Infrared Graphene Heating Technology? 

Monthli is the first pulse therapy menstrual pain relief device to offer Far Infrared Graphene Heating Technology - also known as Radiant Heating Technology. Radiant Heat is a completely safe invisible form of energy that only heats the surfaces of solid objects such as walls, ceilings, floors, and even people. This is achieved by a process called conversion, which means no energy is wasted by having to heat the surrounding air like traditional heating methods. Not only does this significantly aid in menstrual pain relief by allowing the user to feel its effect immediately, but it also promotes blood circulation and can improve muscle stiffness in the neck and lumbar region as well! 

Can I Use My Monthli In Combination With Another Heat Pack? 

As long as you don’t put this additional heat source directly on top or overlapping with your Monthli, this won’t be an issue!  

Do I Need To Clean My Monthli?  

Yes, we recommend using baby wipes to clean any stains, oil, or dust buildup on your device. To clean your Monthli gel pads, please evenly spread a few drops of water on the surface of the gel pad, then gently wipe away with a damp cloth or damp paper towel! Easy! 

Can I Take My Monthli Through Customs Security?  

Absolutely! You will never have to worry about bringing your device on board or going through customs security. Monthli is the ideal travel companion, weighing only 38 grams. It fits easily into any handbag or even your pant pocket.

Is Monthli Latex Free?  

Yas, Monthli is 100% non-toxic & Latex Free! 

How Do I Store My Monthli?  

After use, cover Monthli with the provided gel pad protective storage disc using the reference line as a guide. Until your next use, keep Monthli in a dry & cool space to prevent the buildup of dust, oil, and exposure to sunlight. 

My Monthli Is On, But I Don’t Feel Anything...What Am I Doing Wrong?  

Always double-check to see whether your device is on! Once turned on, you should see your device’s indicator light turn blue. You may want to adjust the position of your Monthli on your body to make sure it is correctly targeting the source of your pain. Once adjusted, please increase the intensity of your pulse therapy until you have reached your desired level of comfort. 

You should also double-check that the gel pads on the back cover the conductive edges. If the gel pads are not properly installed, the device may shut down automatically if the sensors cannot detect the gel pads on your skin or the pulses are not passing through.

If your device is not functioning in this way, please do not hesitate to contact us directly at to speak to one of our customer support team members directly! 

Can I Wear My Monthli In The Shower? 

Definitely not, we know you want to wear Monthli everywhere you go, but it’s best to keep Monthli out of the water as the device is not waterproof.
