If you are pregnant and you take a midol can that cause a miscarriage?
It is important to read the label of your box of Midol. Some types of Midol are NSAIDs - non-steroidal anti-inflammatory drugs, which are contraindicated in pregnancy. It most likely will not cause a miscarriage, but it can create persistent changes in the baby's circulation that can cause grave harm to the baby once it is born.
Other types of Midol are acetaminophen based. These types of Midol are considered safe to use in pregnancy. Make sure you read the box and find out which one you have. Remember pregnant moms - don't take NSAIDs in pregnancy!
This is a partial answer. See above for a more complete answer. No. Midol contains acetaminophen (paracetamol), one of the safest pain relievers there is, and caffeine. Neither of these cause miscarriage. However the literature states that you should consult a health professional before use if you are pregnant or breast feeding.
A previous answer stated that paracetamol (tylenol), could have adverse effects on the fetus. As noted above, it is one of the safest medications available for pain and fever during pregnancy when used in recommended dosages. There is no reason for concern if you took this drug while pregnant!
