For a cold, fever, and sore throat, you can manage symptoms safely at home. To reduce fever and ease throat pain, paracetamol or ibuprofen are highly effective generic options. For nasal congestion, a saline nasal spray or an antihistamine like cetirizine can provide relief. Warm salt-water gargles and non-medicated lozenges are also excellent for soothing your throat. Please stay well-hydrated and get plenty of rest, as these viral symptoms typically resolve on their own within a week. If your fever persists for more than three days or you experience difficulty swallowing or breathing, please consult a doctor for a personalized evaluation.
