Pharyngitis after getting wet in the rain is often due to a viral infection, and symptoms can last a few days. You can take paracetamol for headache and throat pain, drink plenty of warm fluids, do steam inhalation, and rest your voice. Avoid cold drinks and smoking. If there is no improvement after 3 to 4 more days, please see a doctor for further treatment.

Itching and rashes after Cepodem suggest an allergic reaction, and it is good that you stopped the medicine. For now, keep the skin clean and cool, avoid scratching, and you can apply a calming lotion (like calamine) for relief. Do not give any new medicine without a doctor's advice; a paediatrician may prescribe a safe antihistamine if needed. Seek urgent care if there is swelling of the lips/face, breathing difficulty, or the rash spreads rapidly.
