Promethazine is a phenothiazine derivative which blocks postsynaptic mesolimbic dopaminergic receptors in the brain. It exhibits strong α-adrenergic blocking effect and depresses the release of hypothalamic and hypophyseal hormones. It competes with histamine for the H1-receptor; muscarinic blocking effect may be responsible for antiemetic activity. It also reduces stimuli to the brainstem reticular system.Promethazine is well absorbed from the gastrointestinal tract. Clinical effects are apparent within 20 minutes after oral administration and generally last four to six hours, although they may persist as long as 12 hours. Promethazine is metabolized by the liver to a variety of compounds; the sulfoxides of promethazine and N-demethylpromethazine are the predominant metabolites appearing in the urine.

There is epidemiological evidence for the safety of promethazine in pregnancy and animal studies have shown no hazard, nevertheless, it should not be used in pregnancy unless the physician considers it essential. The use of Phenergan is not recommended in the two weeks prior to delivery in view of the risk of irritability and excitement in the neonate. When promethazine has been given in high doses during late pregnancy, promethazine has caused prolonged neurological disturbances in the infant. Promethazine should be used in pregnancy only if the potential benefts to the patient are weighed against the possible risk to the fetus. Promethazine is excreted in breastmilk. There are risks of neonatal irritability and excitement.
The use of promethazine should be avoided in children and adolescents with signs and symptoms suggestive of Reye’s syndrome.
Promethazine may thicken or dry lung secretions and impair expectoration. It should therefore be used with caution in patients with asthma, bronchitis or bronchiectasis.
