Previous terminology
Sexual sadism is the term previously employed by the DSM-III-R, DSM-IV, and DSM-IV-TR, where it was classified as a paraphilia. In these versions of the DSM, sexual sadism pertained only to the infliction of real (not simulated) suffering (p. 530). The condition was renamed sexual sadism disorder in DSM-5. Sexual sadism was the term employed in the DSM-III, classifying the condition as a paraphilia. The DSM-III noted that "the imagery in a Paraphilia, such as simulated bondage, may be playful and harmless and acted out with a mutually consenting partner….In more extreme form, paraphilic imagery is acted out with a nonconsenting partner, and is noxious and injurious to the partner" (p. 267). In DSM-III, sexual sadism could be diagnosed if:

the person repeatedly and intentionally inflicted suffering on a nonconsenting person, to experience sexual excitement
repeatedly or exclusively preferred simulated or mild suffering with a consenting sexual partner
employs extensive, permanent, or potentially fatal suffering to achieve sexual excitement, regardless of the consent of the other person.Sadism was the term employed by the DSM-II. In that manual, the condition was classified as a sexual deviation, which was used to describe "individuals whose sexual interests are directed primarily toward…coitus performed under bizarre circumstances" (p. 44). The term "paraphilia" did not exist in the DSM-II, and diagnoses did not have specific criteria until DSM-III. Sexual sadism was the phrase mentioned in DSM-I as one of the sexual deviations (p. 39), but neither it (nor any of the other sexual deviations) received a specific label or diagnostic criteria.
It is contraindicated for people with a suspected bowel obstruction, in epilepsy, if a stomach operation has been performed in the previous three or four days, if the person has ever had bleeding, perforation or blockage of the stomach, and in newborn babies.The safety of the drug was reviewed by the European Medicines Agency in 2011, which determined that it should not be prescribed in high doses, for periods of more than five days, or given to children below 1 year of age. They suggested its use in older children should be restricted to treating post-chemotherapy or post-surgery nausea and vomiting, and even then only for patients where other treatments have failed. For adults, they recommended its use be restricted to treating migraines and post-chemotherapy or post-surgery patients. Pregnancy
Metoclopramide has long been used in all stages of pregnancy with no evidence of harm to the mother or foetus. A large cohort study of babies born to Israeli women exposed to metoclopramide during pregnancy found no evidence that the drug increases the risk of congenital malformations, low birth weight, preterm birth, or perinatal mortality. A large cohort study in Denmark found, in addition, no association between metoclopramide exposure and miscarriage. Metoclopramide is excreted into milk. Infants
A systematic review found a wide range of reported outcomes for treatment of gastroesophageal reflux disease (GERD) in infants and concluded a "poor" rating of evidence and "inconclusive" rating of safety and efficacy for the treatment of GERD in infants.
