Here are some of the most frequently asked questions…

Kosi™ is a TENS device, which stands for Transcutaneous Electrical Nerve Stimulation. Kosi™ works by passing a tiny electrical current through two pads placed on nerve roots supplying sensory fibers to the uterus and/or lower back. The stimulation, once in place, inhibits pain signals from reaching the brain, causing the muscles in the uterine area to relax and produce a relaxing analgesic effect.

Absolutely! Kosi™ is a pain reliever for primary period pain (dysmenorrhoea). However, it may also assist to reduce secondary period discomfort caused by endometriosis, PCOS, fibroids, adenomyosis, or pelvic inflammatory disease.

You can use Kosi™ as much as you like! Rest assured that the device has undergone extensive clinical testing to verify that it is fully safe for long-term use. If you experience any discomfort or irritation while using Kosi™, we recommend taking small breaks or moving the pads around every few hours. Every body is different, so pay attention to how you feel!

Kosi™ is designed to relieve pain in the lower abdomen and lower back.

You will like Kosi™, but we recognize that everyone’s body is different.
