Fever running into the 5th-6th day needs a cause, not just more Dolo. Antibiotics started blindly often don't cover what is actually there - dengue, typhoid, malaria or a urine/chest infection all look like this in the first week.
Get CBC, dengue NS1/IgM, malaria, widal/typhidot,
CRP and urine routine done today, and show the reports to a physician. Continue Dolo 650 only when temp crosses 100F, plenty of fluids. If breathlessness, bleeding, severe drop in urine or drowsiness - go to hospital immediately. You can consult me on Practo or at Synergy Multispeciality Hospital, Miraj.
