What causes persistent low fever while on Motrin when diagnosed with pneumonia?
Patient: My son was diagnosed with strep last tues with positive strep test. He received penicillin shot that day. Fever continued and cough and pain breathing so we went to Dr. Saturday. They diagnosed with pneumonia and gave z-pak. We continued with low fever since then. Followed up with pediatrician Monday night. He still has low fever as soon as his motrin gets out of his system. It runs only 100.5. But we have been taking motrin since last Tues. It is now the following Wednesday. He says he aches all over. He feels alittle better with motrin. But just lays around not doing much, which is not like him at all. Called Dr. Office we are following up tomorrow. Any suggestions? Doctor: Hi thanks for asking question.Here your son is suffering from strep.pneumonia.Mostly penicillin group of drug are sensitive to streptococci.For strep.pneumonia Amoxiclav is drug of choice.Meanwhile maintain your immunity with water and fruit juice more.If drug is effective then your total count by cbc will decrease along with decreasing clinical symptoms.If response is not good then antibiotic might not effective as resistance may develop against it.Culture and sensitivity report might be helpful.Complete the course of antibiotic and then after if infection has been cleared chest x ray will also show improvement.So your fever might comes because just now you have not completed antibiotic course.You will recover well with time.Don't worry.Wish you good health
