Your symptoms are likely due to a viral throat infection, so antibiotics like Cefadur 500 (Cefadroxil) are usually not needed. You may take Sinarest New (Paracetamol, Phenylephrine, and Chlorpheniramine) to relieve a sore throat, congestion, and runny nose. Warm saltwater gargles and honey in warm water may also help soothe your throat. If your symptoms persist or worsen, please consult a doctor for further advice.
