<s>[INST] My daughter (almost three) got a bad cold after her older sibling. The doctor sent a prescription antibiotic for her as the same with the older sibling. She started taking it Thursday night, what started as a very bad cough like hacking all night and sneezing she now started running a fever today? Could this be from the antibiotic, an allergic reaction or its not strong enough? [/INST] Hi,Nothing to worry, it seems that this is due to having lower respiratory tract infection following by upper respiratory tract infection.Continue with antibiotic medicine, within a day or two she will better once antibiotic will start working.If there is no improvement the consult pediatrician and get examined.Ok and take care. </s>
