Hi, My 2 and half years old son is having cold and cough from past 10days. 6 days after he caught cold and cough, he got fever, for 2 days, everytime, close to 101 My Doctor advised to start on antibiotic, Mox drops if fever doesnt come down within 3 days, else to give mucolite and sinarest AF for 5days. After 2 days fever has come down, but his voice has completly changed, looks like sore throat, cold and cough is still there. He is not eating well. Should i start with antibiotics or just wait.
