The risks to unborn babies and to foetal development when using TENS before 37 weeks into pregnancy are unknown, therefore we do not recommend the use of a TENS machine before you reach this stage of pregnancy.
After 37 weeks into your pregnancy, you can safely use TENS to help provide relief from backache, and for a drug-free alternative form of pain relief during your labour.
We highly recommend:
- Do NOT use during the first three months of pregnancy. It is not known whether TENS may affect foetal development.
- Do NOT use on the abdomen in the later stages of pregnancy. Stop using immediately if you experience unexpected contractions.
