One of the most common drugs used in the labour ward is pethidine, a synthetic, addictive, narcotic drug that is similar to morphine. In Britain it is also known as meperidine, and in America it is known as Demerol.
These drugs are used to induce (start) or augment (speed) labor; facilitate uterine contractions following a miscarriage; induce abortion; or reduce hemorrhage following childbirth or abortion. The three uterotonics used most frequently are the oxytocins, prostaglandins, and ergot alkaloids.
