Hi, Welcome to Health care magic forum. You had cold, and fever, it may be allergic , viral, viral with bacterial super infection,or may be the bacterial infection. If it is viral infection, then you need not use the antibiotic if it is other form antibiotic is necessory. If the sputum become orange, or brown it is infected with bacteria. In that case consult your doctor. I usually prescribe to my patient with such symptoms, cifixime, citrizine, phenyl propolamine, and paracetamol. Take more of green leafy vegetables, pulses, sprouts,and protein rich foods to hasten the recovery. Wishing for a quick and complete recovery. Thank you.
