Doctors usually tell women to avoid medicines during pregnancy, if
possible, especially during the first 3 months. That is when a baby's organs
form. But sometimes you have to take medicine to treat a health problem, such

So first your doctor or midwife will
look at the risk. Is the risk of taking a medicine higher than the risk of not
treating your illness? If you or your baby would face worse problems without

It can be hard to know if a medicine is safe for your baby. Most
medicines are not studied in pregnant women. That's because researchers worry about

your doctor or midwife prescribes. Talk to your doctor or midwife
about which type of vitamin you should take. In some cases, doctors and
midwives prescribe extra iron or extra folic acid.
