Hi, I had gone through your question and understand your concerns. Febrex plus contains Chlorpheniramine , Paracetamol , Sodium Citrate , used usually for common cold with fever , you have not mentioned strength of paracetamol, and dose of medicine you are taking . Meftal P in prescribed doses can be taken with it , but instead of using two medicines you can always do tepid sponging to bring down fever , if otherwise baby is active , usually seasonal illness takes 3-5 days in recovery . Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. Wishing your baby good health. • DISCLAIMER: - All the information provided here is for information purpose only , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
