Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.
This medicine must not be used by women who are pregnant, or who are planning a pregnancy, because it can be harmful to an unborn baby. Misoprostol mimicks the effects of prostaglandins involved in starting labour and causes contractions of the womb. This could result in a miscarriage. Naproxen may delay labour, increase the length of labour and cause complications in the newborn baby. Some evidence suggests that NSAIDs should also be avoided by women attempting to conceive, as they may temporarily reduce female fertility during treatment and may also increase the risk of miscarriage or malformations.
