Objective: To study the pattern of drug prescription among pregnant women referred to the antenatal care clinic of a tertiary care centre in India. Method: It was a retrospective analysis of pattern of drug prescription in 1000 consecutive pregnant patients referred to antenatal clinic of the hospital between January 2016 and December 2016. Results: Average number of drugs prescribed to each patient was 3.92 with a range of 1-15. In 49.9% patients drugs were prescribed empirically. Average number of empirical drugs prescribed per patient was 2.02 with a range of 0-9. In our study, 93.9 % patients received at least one FDA category A drug while 14.2 % patients received FDA category X drugs. In 142 patients receiving category X drugs, 94(66.1%) were prescribed these drugs empirically. Category X drugs was given to 57.4 % patients before 16 weeks of gestation. Iron was the most commonly prescribed drug in category A while Injection Human Chorionic Gonadotrophin was most commonly prescribed category X drug.

Unindicated prescription of drugs leads to increased financial burden on the pregnant women while also exposing mother and fetus to deleterious effects of these drugs.
