Renal Dose Adjustments

CrCl less than 30 mL/min: 5 mg orally or chewed once a day.

Use of Omcet 10mg 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 Omcet 10mg in such patients.

Liver Dose Adjustments

5 mg orally or chewed once a day

Use of Omcet 10mg 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 Omcet 10mg 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

Omcet 10mg 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 Omcet 10mg?

Tablet: Concurrent use with alcohol may potentiate the CNS depressant effects of Omcet 10mg; maprotiline or tricyclic antidepressants may potentiate the anticholinergic effects of either these medications or Omcet 10mg.

Monoamine oxidase (MAO) inhibitors are not recommended because the use may prolong and intensify the anticholinergic and CNS depressant effects of Omcet 10mg.

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 Omcet 10mg with pseudoephedrine, cimetidine, ketoconazole, erythromycin and azithromycin. Small decrease in Omcet 10mg clearance is observed when theophylline (400 mg once daily) is taken with Omcet 10mg. However, disposition of theophylline was not altered by concomitant Omcet 10mg administration. Concomitant administration of Omcet 10mg and macrolides or ketoconazole has never resulted clinically relevant EGG changes. Extent of exposure to Omcet 10mg was increased by 40% when ritonavir is taken with Omcet 10mg. Disposition of ritonavir was slightly altered further to concomitant Omcet 10mg administration.

What are the possible side effects of Omcet 10mg?

Pediatric studies were conducted with Omcet 10mg hydrochloride. More than 1300 pediatric patients aged 6 to 11 years with more than 900 treated with Omcet 10mg 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 Omcet 10mg, 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 Omcet 10mg (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 Omcet 10mg (0.25 mg/kg bid).

The majority of adverse reactions reported in pediatric patients aged 2 to 11 years with Omcet 10mg 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 Omcet 10mg hydrochloride was uncommon (0.4% on Omcet 10mg hydrochloride vs. 1.0% on placebo).

Table 1 lists adverse experiences which were reported for Omcet 10mg 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 Omcet 10mg 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 Omcet 10mg and placebo treatment groups in each study. Somnolence occurred with essentially the same frequency in patients who received Omcet 10mg hydrochloride and patients who received placebo. In a study of 1 week duration in children 6 to 11 months of age, patients who received Omcet 10mg 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 Omcet 10mg compared to patients who received placebo (9.0% v. 5.3%). In those patients who received 5 mg or more per day of Omcet 10mg as compared to patients who received placebo, fatigue (3.6% v. 1.3%) and malaise (3.6% v. 1.8%) occurred more frequently.

The following events were observed infrequently (less than 2%), in either 3982 adults and children 12 years and older or in 659 pediatric patients aged 6 to 11 years who received Omcet 10mg hydrochloride in U.S. trials, including an open adult study of six months duration.
