First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This Phase 3 trial tested whether a single pill containing paracetamol (pain reliever/fever reducer), fexofenadine (antihistamine), and phenylephrine (decongestant) works better than a placebo for treating cold and flu symptoms. 567 adults in Brazil took the combo pill or a placebo every 8 hours for up to 3 days. Researchers measured symptom relief using a questionnaire that tracked nasal congestion, runny nose, sneezing, headache, muscle aches, sore throat, cough, and fever.
