Epinephrine or adrenaline is a naturally occurring catecholamine. It is a hormone, neurotransmitter and medication. It is normally produced by both the adrenal glands and certain neurons. It plays an important role in the fight or flight response by increasing blood flow to muscles, output of heart, pupil dilatation and blood sugar. It acts by binding  to alpha and beta receptors.

As a medication it is used to treat a number of conditions including anaphylaxis, cardiac arrest and superficial bleeding. It may also be used for asthma when other treatments are not effective and this is one of the life saving drugs. There might be emergent occasions where doctors have to administer it to pregnant women. Safety of its use in pregnancy is unclear. So in present study attempts have been made to explore its prenatal effects by reviewing previous studies performed on the topic.
