    If you are pregnant then you should consult your doctor before taking Mefenamic acid. It is definitely not suitable for those in the last 3 months of pregnancy, but affects on the baby in the first 6 months are not known. This means it’s not usually recommended but your doctor may prescribe it you if they feel it necessary. However, you should not take Mefenamic acid if you are trying to get pregnant, as the drug will make it more difficult.

    If you are breastfeeding then you should be aware that Mefenamic acid can be passed into your breast milk and should therefore not be taken during this time unless expressly instructed to do so by your doctor.
