Antihistamine–decongestant combinations
Two studies compared antihistamine–decongestant (brompheniramine–phenylpropanolamine) combinations in children aged 6 months to 5 years, and neither was more effective than placebo. In one of the studies, a higher proportion of children were asleep in the active treatment group (46.6%) than in the placebo group (26.5%, P ¼ 0:53).
