Hello,
With all the history given here, I would suggest to stop all the medicines. Let me explain, if this is febrile condition then the underlying cause of it needs to be known.
Without knowing the underlying cause or a proper diagnosis of the symptoms, it cannot be treated as it is. It may jeopardize the condition.
I would suggest you to get all routine investigations done like routine blood work, X-ray chest, urine test, stool examination, and most important one, clinical examination.
With all of these reports, I would suggest to consult a physician as such a condition cannot be managed with multiple drugs without knowing the diagnosis.
Steroid is highly contraindicated if it is a febrile condition. In my opinion, get yourself hospitalized.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Hussain
