Promethazine is a first-generation H1 receptor antagonist of the phenothiazine chemical class used medically as an antihistamine antiemetic. It has a strong sedative effect and in some countries is prescribed for insomnia when benzodiazepines are contraindicated. It is available over the counter in the United Kingdom, Australia, Switzerland, and many other countries, but by prescription in the United States (brand names Phenergan, Promethegan, Romergan, Fargan, Farganesse, Prothiazine, Avomine, Atosil, Receptozine, Lergigan, and Sominex in the UK).
