What about other painkillers?
Medicines containing ibuprofen, diclofenac, naproxen and acetylsalicylic acid (aspirin) are anti-inflammatory drugs (NSAIDs). In the first half of pregnancy, it is not wise to use these unless explicitly prescribed by a doctor. Taking NSAIDs increases the risk of miscarriage. Your baby may also have heart defects or an open abdomen (gastroschisis).
In the second half of pregnancy it is not recommended at all to use NSAIDs. It can slow down contractions and you may need other drugs to get your delivery going. Your baby can also have several serious health problems.
