Safe Use of Medicines during Pregnancy

Importance of safe use of medicines during pregnancy
Improper use of medicines may also lead to premature babies, underweight babies, and stillborn births, and in less desirable cases teratogenicity and birth defects. However, in patients with existing medical condition, premature withdrawal or negligence of due medical treatment may result in long-term complications on both the mother and the baby. Pregnant women should always seek medical advice prior to consume or discontinue any medications.
