What is M Cit DT?
M Cit DT is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
M Cit DT is used to treat cold or allergy symptoms such as sneezing, itching, watery eyes, or runny nose.
M Cit DT is also used to treat itching and swelling caused by chronic urticaria (hives).
M Cit DT may also be used for purposes not listed in this medication guide.
M Cit DT indications
Perennial Allergic Rhinitis: M Cit DT hydrochloride syrup is indicated for the relief of symptoms associated with perennial allergic rhinitis due to allergens such as dust mites, animal dander and molds in children 6 to 23 months of age. Symptoms treated effectively include sneezing, rhinorrhea, postnasal discharge, nasal pruritus, ocular pruritus, and tearing.
Chronic Urticaria: M Cit DT hydrochloride syrup is indicated for the treatment of the uncomplicated skin manifestations of chronic idiopathic urticaria in children 6 months to 5 years of age. It significantly reduces the occurrence, severity, and duration of hives and significantly reduces pruritus.

M Cit DT description
M Cit DT HCl is a piperazine derivative and a metabolite of hydroxyzine. It competes reversibly with histamine to block the histamine (H1) receptor sites. M Cit DT HCl is considered a long-acting nonsedating antihistamine and has some mast-cell stabilizing activity.

Renal Dose Adjustments
CrCl less than 30 mL/min: 5 mg orally or chewed once a day.
Use of M Cit DT is not recommended in children under 6 years of age with renal impairment due to the difficulty in reliably administering doses less than 2.5 mg (1/2 teaspoonful) and the lack of pharmacokinetic and safety information of M Cit DT in such patients.
Liver Dose Adjustments
5 mg orally or chewed once a day
Use of M Cit DT is not recommended in children under 6 years of age with hepatic impairment due to the difficulty in reliably administering doses less than 2.5 mg (1/2 teaspoonful) and the lack of pharmacokinetic and safety information of M Cit DT in such patients.
Precautions
In clinical trials, the occurrence of somnolence has been reported. Due caution should therefore be exercised when driving a car or operating potential dangerous machinery. Concurrent use of alcohol or other CNS depressants should be avoided because additional reductions in alertness and additional impairment of CNS performance may occur.
Dialysis
M Cit DT is not significantly removed by hemodialysis, thus supplementary dosing is not required following hemodialysis. The recommended dosage for patients on hemodialysis is 5 mg orally or chewed once a day.

What other drugs will affect M Cit DT?
Tablet: Concurrent use with alcohol may potentiate the CNS depressant effects of M Cit DT; maprotiline or tricyclic antidepressants may potentiate the anticholinergic effects of either these medications or M Cit DT.
Monoamine oxidase (MAO) inhibitors are not recommended because the use may prolong and intensify the anticholinergic and CNS depressant effects of M Cit DT.
Concurrent use with ototoxic medications may mask the symptoms of ototoxicity eg, tinnitus, dizziness or vertigo; photosensitizing medications may cause additive photosensitizing effects.
Syrup: No interaction is observed for M Cit DT with pseudoephedrine, cimetidine, ketoconazole, erythromycin and azithromycin. Small decrease in M Cit DT clearance is observed when theophylline (400 mg once daily) is taken with M Cit DT. However, disposition of theophylline was not altered by concomitant M Cit DT administration. Concomitant administration of M Cit DT and macrolides or ketoconazole has never resulted clinically relevant EGG changes. Extent of exposure to M Cit DT was increased by 40% when ritonavir is taken with M Cit DT. Disposition of ritonavir was slightly altered further to concomitant M Cit DT administration.

What are the possible side effects of M Cit DT?
Pediatric studies were conducted with M Cit DT hydrochloride. More than 1300 pediatric patients aged 6 to 11 years with more than 900 treated with M Cit DT hydrochloride at doses of 1.25 to 10 mg per day were included in controlled and uncontrolled clinical trials conducted in the United States. The duration of treatment ranged from 2 to 12 weeks. Placebo-controlled trials up to 4 weeks duration included 168 pediatric patients aged 2 to 5 years who received M Cit DT, the majority of whom received single daily doses of 5 mg. A placebo-controlled trial 18 months in duration included 399 patients aged 12 to 24 months treated with M Cit DT (0.25 mg/kg bid), and another placebo-controlled trial of 7 days duration included 42 patients aged 6 to 11 months who were treated with M Cit DT (0.25 mg/kg bid).
The majority of adverse reactions reported in pediatric patients aged 2 to 11 years with M Cit DT hydrochloride were mild or moderate. In placebo-controlled trials, the incidence of discontinuations due to adverse reactions in pediatric patients receiving up to 10 mg of M Cit DT hydrochloride was uncommon (0.4% on M Cit DT hydrochloride vs. 1.0% on placebo).
Table 1 lists adverse experiences which were reported for M Cit DT hydrochloride 5 and 10 mg in pediatric patients aged 6 to 11 years in placebo-controlled clinical trials in the United States and were more common with M Cit DT hydrochloride than placebo. Of these, abdominal pain was considered treatment-related and somnolence appeared to be dose-related, 1.3% in placebo, 1.9% at 5 mg and 4.2% at 10 mg. The adverse experiences reported in pediatric patients aged 2 to 5 years in placebo-controlled trials were qualitatively similar in nature and generally similar in frequency to those reported in trials with children aged 6 to 11 years.
In the placebo-controlled trials of pediatric patients 6 to 24 months of age, the incidences of adverse experiences, were similar in the M Cit DT and placebo treatment groups in each study. Somnolence occurred with essentially the same frequency in patients who received M Cit DT hydrochloride and patients who received placebo. In a study of 1 week duration in children 6 to 11 months of age, patients who received M Cit DT exhibited greater irritability/fussiness than patients on placebo. In a study of 18 months duration in patients 12 months and older, insomnia occurred more frequently in patients who received M Cit DT compared to patients who received placebo (9.0% v. 5.3%). In those patients who received 5 mg or more per day of M Cit DT as compared to patients who received placebo, fatigue (3.6% v. 1.3%) and malaise (3.6% v. 1.8%) occurred more frequently.
