A child's cough may be mild during the day but worsen at night, possibly due to chronic bronchitis or gastroesophageal reflux disease (GERD). If the cough is caused by chronic bronchitis, treatment may include medications such as albuterol inhalers, under a doctor's guidance. If it is due to GERD, acid-suppressing medications such as omeprazole enteric-coated capsules may be taken as directed by a physician. However, omeprazole enteric-coated capsules are recommended for use in individuals aged 14 years and older.
