Hi, do read the fine print on the box of medicated plaster to see if your wife is sensitive to any ingredients. If unsure, do check with your gynae.
Generally safe as the absorption is very little - but try to limit use and avoid if possible. I suggest to use a maternity support belt instead
Avoid all medicated plaster including koyok plaster. is not recommended for pregnant women.
yes should be ok, I used koyok plaster several times on my back and arm.
My Gynae say using koyok plaster is not advisable.
