Revised: 05/2020 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
In the following description of clinical trials experience, adverse reactions are listed regardless of causality assessment.
The most common adverse reactions (incidence ≥5% and greater than placebo;
listed in descending order of frequency) in controlled clinical trials were: upper respiratory infection, fever, headache, pharyngitis, cough, abdominal pain, diarrhea, otitis media, influenza, rhinorrhea, sinusitis, otitis.
Adults and Adolescents 15 Years of Age and Older with Asthma Montelukast sodium has been evaluated for safety in approximately 2950 adult and adolescent patients 15 years of age and older in clinical trials.
In placebo-controlled clinical trials, the following adverse experiences reported with montelukast sodium occurred in greater than or equal to 1% of patients and at an incidence greater than that in patients treated with placebo: Table 1: Adverse Experiences Occurring in ≥1% of Patients with an Incidence Greater than that in Patients Treated with Placebo Montelukast Sodium 10 mg/day Placebo (%) (%) (n=1955) (n=1180) Body As A Whole Pain, abdominal 2.9 2.5 Asthenia/fatigue 1.8 1.2 Fever 1.5 0.9 Trauma 1.0 0.8 Digestive System Disorders Dyspepsia 2.1 1.1 Pain, dental 1.7 1.0 Gastroenteritis, infectious 1.5 0.5 Nervous System/Psychiatric Headache 18.4 18.1 Dizziness 1.9 1.4 Respiratory System Disorders Influenza 4.2 3.9 Cough 2.7 2.4 Congestion, nasal 1.6 1.3 Skin/Skin Appendages Disorder Rash 1.6 1.2 Laboratory Adverse Experiences * ALT increased 2.1 2.0 AST increased 1.6 1.2 Pyuria 1.0 0.9 *Number of patients tested (montelukast sodium and placebo, respectively): ALT and AST, 1935, 1170;

5 WARNINGS AND PRECAUTIONS • Do not prescribe montelukast sodium to treat an acute asthma attack ( 5.2 ).
• Advise patients to have appropriate rescue medication available ( 5.2 ).
