Hello, I understand your concern. I am Dr. Arun Tank, infectious diseases specialist, answering your query. In my opinion it is not the reaction to drugs. Reaction to drugs appears immediately. It appears after a weeks period. In my advice continue and complete the treatment as per the schedule. I will be happy to answer your further concern, you can ask me on bit.ly/DrArun. Thank you. Dr Arun Tank Infectious diseases specialist.
