As he was having some infection, he was admitted in the  hospital and was given 9 doses of antibiotics as injection 12 th hourly and on discharge doctor advised to give him 3.5ml antibiotics syrup for 5 days 12th hourly. As per the prescription the last dose is on today morning. But there is not enough quantity of syrup in the bottle to give the last dose. What should I do? Should I skip the last dose? Or Should I give the remaining syrup? Or Should I buy a new bottle and give the accurate quantity? Please guide me. Thanking you.
