Montelukast is not expected to affect your ability to drive a car or operate machinery. However, individual responses to medication may vary. SINGULAIR administered once daily had a safety profile consistent with that observed in patients with seasonal allergic rhinitis and similar to that of placebo.

The incidence of somnolence was similar to that of placebo. Pediatric Patients 6 Months to 14 Years of Age with Perennial Allergic Rhinitis The safety in patients 2 to 14 years of age with perennial allergic rhinitis is supported by the safety in patients 2 to 14 years of age with seasonal allergic rhinitis.

The safety in patients 6 to 23 months of age is supported by data from pharmacokinetic and safety and efficacy studies in asthma in this pediatric population and from adult pharmacokinetic studies.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and lymphatic system disorders: Respiratory, thoracic and mediastinal disorders: Most of these occurred in combination with other confounding factors, such as use of other medications, or when SINGULAIR was administered to patients who had underlying potential for liver disease such as alcohol use or other forms of hepatitis.

Skin and subcutaneous tissue disorders: Musculoskeletal and connective tissue disorders: Renal and urinary disorders: General disorders and administration site conditions: Patients with asthma on therapy with SINGULAIR may present with systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome , a condition which is often treated with systemic corticosteroid therapy.

These events have been sometimes associated with the reduction of oral corticosteroid therapy. Patients should be advised to have appropriate rescue medication available. Although SINGULAIR is effective in improving airway function in asthmatics with documented aspirin sensitivity, it has not been shown to truncate bronchoconstrictor response to aspirin and other non-steroidal anti-inflammatory drugs in aspirinsensitive asthmatic patients [see Clinical Studies ].

Post-marketing reports with SINGULAIR use include agitation, aggressive behavior or hostility, anxiousness, depression, disorientation, disturbance in attention, dream abnormalities, hallucinations, insomnia, irritability, memory impairment, restlessness, somnambulism , suicidal thinking and behavior including suicide , and tremor.

Patients and prescribers should be alert for neuropsychiatric events. Patients should be instructed to notify their prescriber if these changes occur. Eosinophilic Conditions Patients with asthma on therapy with SINGULAIR may present with systemic eosinophilia , sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome , a condition which is often treated with systemic corticosteroid therapy. Phenylketonuria Phenylketonuric patients should be informed that the 4-mg and 5-mg chewable tablets contain phenylalanine a component of aspartame , 0.

Information for Patients Patients should be advised to take SINGULAIR daily as prescribed, even when they are asymptomatic , as well as during periods of worsening asthma, and to contact their physicians if their asthma is not well controlled.

Patients should be advised that, while using SINGULAIR, medical attention should be sought if short-acting inhaled bronchodilators are needed more often than usual, or if more than the maximum number of inhalations of short-acting bronchodilator treatment prescribed for a hour period are needed. Phenylketonuric patients should be informed that the 4-mg and 5-mg chewable tablets contain phenylalanine a component of aspartame.

The estimated exposure in rats was approximately and 75 times the AUC for adults and children, respectively, at the maximum recommended daily oral dose. The estimated exposure in mice was approximately 45 and 25 times the AUC for adults and children, respectively, at the maximum recommended daily oral dose. Montelukast demonstrated no evidence of mutagenic or clastogenic activity in the following assays: Teratogenic Effect No teratogenicity was observed in rats and rabbits at doses approximately and times, respectively, the maximum recommended daily oral dose in adults based on AUCs [see Nonclinical Toxicology].

Most of these women were also taking other asthma medications during their pregnancy. Nursing Mothers Studies in rats have shown that montelukast is excreted in milk. It is not known if montelukast is excreted in human milk.

The efficacy of SINGULAIR for the treatment of seasonal allergic rhinitis in pediatric patients 2 to 14 years of age and for the treatment of perennial allergic rhinitis in pediatric patients 6 months to 14 years of age is supported by extrapolation from the demonstrated efficacy in patients 15 years of age and older with allergic rhinitis as well as the assumption that the disease course, pathophysiology and the drug's effect are substantially similar among these populations.

Efficacy of SINGULAIR in this age group is extrapolated from the demonstrated efficacy in patients 6 years of age and older with asthma and is based on similar pharmacokinetic data, as well as the assumption that the disease course, pathophysiology and the drug's effect are substantially similar among these populations. Efficacy in this age group is supported by exploratory efficacy assessments from a large, well-controlled safety study conducted in patients 2 to 5 years of age.

Efficacy of SINGULAIR in this age group is extrapolated from the demonstrated efficacy in patients 6 years of age and older with asthma based on similar mean systemic exposure AUC , and that the disease course, pathophysiology and the drug's effect are substantially similar among these populations, supported by efficacy data from a safety trial in which efficacy was an exploratory assessment.

The safety of SINGULAIR 4-mg and 5-mg chewable tablets in pediatric patients aged 2 to 14 years with allergic rhinitis is supported by data from studies conducted in pediatric patients aged 2 to 14 years with asthma. The safety of SINGULAIR 4-mg oral granules in pediatric patients as young as 6 months of age with perennial allergic rhinitis is supported by extrapolation from safety data obtained from studies conducted in pediatric patients 6 months to 23 months of age with asthma and from pharmacokinetic data comparing systemic exposures in patients 6 months to 23 months of age to systemic exposures in adults.

The safety and effectiveness in pediatric patients below the age of 12 months with asthma, 6 months with perennial allergic rhinitis, and 6 years with exercise-induced bronchoconstriction have not been established. Growth Rate in Pediatric Patients A week, multi-center, double-blind, randomized, active- and placebo-controlled parallel group study was conducted to assess the effect of SINGULAIR on growth rate in patients with mild asthma, aged 6 to 8 years. Sixty percent of patients were not on any other controller therapy.

Montelukast improved daytime symptoms including coughing, wheezing, trouble breathing and activity limitation and night- time symptoms compared with placebo. Montelukast also decreased 'as needed' beta- agonist use and corticosteroid rescue for worsening asthma compared with placebo. Patients receiving montelukast had more days without asthma than those receiving placebo. A treatment effect was achieved after the first dose.

Significant reduction of exercise-induced bronchoconstriction EIB was demonstrated in a week study in adults maximal fall in FEV1 This effect was consistent throughout the week study period. Reduction in EIB was also demonstrated in a short term study in paediatric patients 6 to 14 years of age maximal fall in FEV1 The effect in both studies was demonstrated at the end of the once-daily dosing interval.

The percentage reduction in yearly EE rate was In an 8-week study in paediatric patients 6 to 14 years of age, montelukast 5 mg once daily, compared with placebo, significantly improved respiratory function FEV1 8. In a month study comparing the efficacy of montelukast to inhaled fluticasone on asthma control in paediatric patients 6 to 14 years of age with mild persistent asthma, montelukast was non-inferior to fluticasone in increasing the percentage of asthma rescue-free days RFDs.

Averaged over the month treatment period, the percentage of asthma RFDs increased from Both montelukast and fluticasone also improved asthma control on secondary variables assessed over the 12 month treatment period: The between group difference in LS means for the percentage of days with beta-agonist use was 2.

The between group difference in LS means was 7. In a placebo-controlled study in paediatric patients 6 months to 5 years of age who had intermittent asthma but did not have persistent asthma, treatment with montelukast was administered over a month period, either as a once-daily 4 mg regimen or as a series of day courses that each were started when an episode of intermittent symptoms began. No significant difference was observed between patients treated with montelukast 4 mg or placebo in the number of asthma episodes culminating in an asthma attack, defined as an asthma episode requiring utilization of health-care resources such as an unscheduled visit to a doctor's office, emergency room, or hospital or treatment with oral, intravenous, or intramuscular corticosteroid.

For the 10 mg film- coated tablet, the mean peak plasma concentration Cmax is achieved three hours Tmax after administration in adults in the fasted state.

The oral bioavailability and Cmax are not influenced by a standard meal. Safety and efficacy were demonstrated in clinical trials where the 10 mg film-coated tablet was administered without regard to the timing of food ingestion.

Montelukast 5 mg chewable tablets

In addition, singulair chew tabs 4mg, concentrations of radiolabeled material at 24 hours post-dose were minimal in all other tissues. However, compared with beclomethasone, a high percentage of patients treated with montelukast achieved similar clinical responses e. Therefore, montelukast is not anticipated to alter the metabolism of drugs metabolized by this enzyme e. Patients should be instructed to notify their prescriber if these changes occur. Clinical 4mg and safety In studies in adults, montelukast 10 mg once daily, compared with placebo, demonstrated chew improvements in morning FEV1 Because these reactions are reported voluntarily from a population of uncertain size, it is singulair always tab to reliably tab their frequency or establish a causal relationship to drug exposure. Information for Patients Patients should be advised to take SINGULAIR daily as prescribed, even when 4mg are asymptomaticsingulair chew tabs 4mg, as well as during periods of worsening asthma, and to contact their physicians if their asthma is not well controlled. Teratogenic Singulair No teratogenicity was observed in rats and rabbits at doses approximately and times, respectively, the maximum recommended daily oral dose in adults based on AUCs [see Nonclinical Toxicology]. There chew no side effects reported in the majority of overdose reports, singulair chew tabs 4mg. Pediatric Patients 6 Months to 14 Years of Age with Perennial Allergic Rhinitis The safety in patients 2 to 14 years of age with perennial allergic rhinitis is supported by the safety in patients 2 to 14 years of age with seasonal allergic rhinitis. Improvement in patient-reported daytime and night-time asthma symptoms scores was significantly better than placebo. How to take Montelukast 4. In vitro studies using human liver microsomes indicate that cytochromes P 3A4, 2A6 and 2C9 are involved in the metabolism of montelukast.
