To alleviate the itching, we recommend UDCA (20 mg/kg/day) and rifampicin (up to 10 mg/kg/day), before attempting antihistamines such as
alimemazine, opiate- (naltrexone) or serotonin-antagonists (ondansetron).
In the patients whose urine tested erroneously positive, medical records showed the administration of cyamemazine (n = 40; dose per day ranging from 100 to 600 mg) or of levomepromazine (n = 2; dose per day of 125 and 150 mg), both compounds administered either alone or with
alimemazine (n = 8; dose ranging from 30 to 40 mg per day).
Barbiturates (phenobarbital, butobarbital, and secobarbital), meprobamate, antidepressant agents (amitriptyline, nortriptyline, imipramine, and clomipramine), phenothiazines (acepromazine,
alimemazine, and cyamemazine), and benzodiazepines (diazepam, bromazepam, flunitrazepam, clonazepam, alprazolam, nitrazepam, nordazepam, and prazepam) were extracted from 5 mL of serum, 20 mL of urine, or 20 mL of gastric lavage fluid by Tox-Elut[R] from Varian (Harbor City, CA).
