Description

Promethazine is a neuroleptic medication and first-generation antihistamine of the phenothiazine family. The drug has strong sedative and weak antipsychotic effects. It also reduces motion sickness and has antiemetic and anticholinergic properties (via its action on the Dopamine receptor D2). In some countries it is prescribed for insomnia when benzodiazepines are contraindicated. It is available in many countries under many brand names. Promethazine was developed in the mid 1940s when a team of scientists from Rhône-Poulenc laboratories were able to synthesize it from phenothiazine and a diamine side chain of diphenhydramine.

If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

In case of skin contact

Wash off with soap and plenty of water. Consult a physician.

In case of eye contact

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

SYMPTOMS: Symptoms of exposure to this compound include excitement, sleepiness, convulsions and rigidity. Other symptoms include leukopenia, agranulocytosis, drowsiness, confusion and stupor. Acute transitory myopia may occur. Central nervous system effects may also occur. It may cause an increase in blood pressure, mild hypotension, jaundice, extra-pyramidal reactions and photosensitivity. It may also cause dizziness, central nervous system depression, vomiting, local anesthesia, abdominal pain, diarrhea and dryness of the mouth, throat and nose. Symptoms of exposure to this type of compound include muscular weakness, tachycardia, nausea, sedation, tinnitus, lassitude, incoordination, fatigue, blurred vision, diplopia, euphoria, nervousness, insomnia, tremors, loss of appetite, epigastric distress, constipation, cough, urinary retention or frequency, dysuria, palpitation, headache, tightness of the chest, tingling, heaviness and weakness of the hands, allergic dermatitis, fever, hemolytic anemia (rare), fixed and dilated pupils, and flushing. In children, exposure can cause hallucinations, excitement, ataxia, incoordination, athetosis and convulsions. ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of hydrochloric acid, sulfur oxides and nitrogen oxides.

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Treatment of phenothiazine overdosage generally involves symptomatic and supportive care. There is no specific antidote for phenothiazine intoxication; however, anticholinergic antiparkinsonian drugs may be useful in controlling extrapyramidal reactions associated with phenothiazine overdosage. Following acute ingestion of the drugs, the stomach should be emptied by gastric lavage and consideration also should be given to repeated doses of activated charcoal. If the patient is comatose, having seizures or a dystonic reaction, or lacks the gag reflex, gastric lavage may be performed if an endotracheal tube with cuff inflated is in place to prevent aspiration of gastric contents. Gastric lavage may be useful even several hours after the drug has been ingested, since GI motility may be greatly reduced following overdosage of phenothiazines. Induction of emesis should generally not be attempted, since a phenothiazine-induced dystonic reaction of the head or neck may result in aspiration of vomitus during emesis. Administration of a saline cathartic may be beneficial in enhancing evacuation of the drug from the GI tract, especially following ingestion of extended-release preparations (eg, Spansules). /Phenothiazine General Statement/
