<s>[INST] My 2 1/2 month old son has a cough, low fever, lost his voice, is congested but no runny nose. Just a mucusy clogged sounding cough and tears when he coughs. Very tired and can t sleep unless very elevated. [/INST] Hi...Thank you for consulting in Health Care magic.Cough and cold are viral 95% of the times in children. For cold (AT THIS AGE) you can use saline nasal decongestants.Paracetamol can be given in the dose of 15mg/kg/dose (max ceiling dose 500mg) every 4-6th hourly, that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol.Do not use any other medicines. Not safe and not licensed at this age.Regards - Dr. Sumanth </s>
