Beurer EM 50 Menstrual Relax TENS Unit

The Beurer EM 50 Menstrual Relax is a small, wearable TENS and heat device designed to ease period pain and discomfort caused by endometriosis. It combines Transcutaneous Electrical Nerve Stimulation (TENS) with a soothing heat program in one discreet unit that sits against your lower abdomen, giving you a medication-free option you can use at home or while you get on with your day.

Because it's rechargeable via USB-C and weighs only around 47 g, the EM 50 is easy to slip under your clothing and take with you. You choose from 15 TENS intensity levels and a single heat program that warms to 43 °C, so you can adjust the sensation to what feels comfortable for you on the day. It's an approved medical device, certified by SAHPRA in South Africa and used in the EU, and it comes with a 5-year warranty.

How it Works

• TENS stimulation: The device sends a low electrical current through self-adhesive gel pads on the skin, which is designed to help provide temporary relief from menstrual and endometriosis pain in the lower abdomen.
• Soothing heat: A single heat program warms to 43 °C, adding gentle warmth alongside the TENS stimulation for added comfort.
• Body-contact detection: The Menstrual Relax detects whether it's properly in contact with your body. If contact is insufficient, it beeps and switches itself off.
• Automatic session timing: Each treatment lasts 20 minutes, after which the device switches off automatically.

What the clinical data shows

Beurer reports that the EM 50 Menstrual Relax is clinically proven to be effective for menstrual cramps and endometriosis pain. According to the supplied studies, over 80% of users experienced pain relief during the first three days of their cycle, over 96% would recommend it, and 98% said they would continue using it for longer-term relief. As with any pain-relief approach, individual results vary, and TENS does not suit everyone.

How to Use

1. Before first use, charge the device for at least 2 hours using the supplied USB-C cable and a compatible USB power source (max. 5 V / 2 A). A 2-amp supply gives the best performance; charging from a 1-amp charger, laptop or low-output USB port can mean longer charging times and reduced heat or intensity.
2. Before each application, clean the skin and avoid using any cream or oils, as these stop the gel pads from adhering properly.
3. Place the device on your lower abdomen and choose your TENS intensity level and the heat program to suit you.
4. The device automatically switches off after 20 minutes. Wait at least 30 minutes before starting another session.

If the gel pads stop sticking, wipe the adhesive surface with a damp, lint-free cloth (no chemical or abrasive cleaners), let them air-dry, and reattach. If continuous beeping persists after cleaning, it's time to replace the pads. You get up to 6 uses per charge (6 x 20-minute sessions), and the reusable gel pads are easy to replace when they wear out.

Pandylane Pro Tip

Pandylane Pro Tip: Charge from a 2-amp (2000 mA) wall adaptor rather than a laptop or low-output USB port — a full-strength charge helps the device deliver its full heat and intensity, and you'll get closer to the six sessions per charge.
