For your fever, an over-the-counter fever reducer like Paracetamol (Acetaminophen) or Ibuprofen can help. For your runny nose and cold symptoms, an antihistamine such as Loratadine or Cetirizine can provide relief. Be sure to stay well-hydrated, get plenty of rest, and avoid taking multiple medications with the same active ingredients. Always read the package labels for correct dosages. If your fever persists for more than three days, or if you develop breathing difficulties, please consult a doctor immediately for a personalized evaluation.
