# Nasal Spray calculation of quantity

Fluticasone Propionate nasal spray 50 MCG. Directions say, use two sprays in each nostril once daily for 30 days.There are 50mcg per spray. Therefore, 4 sprays daily multiplied by 50mcg per spray, equals 200 mcg needed. One bottle contains 120 metered sprays and 16g net fill weight. Ndc 60505-0829-1. Pharmacy gave 1 bottle with a Qty of 16.

Should the Qty have been 32 and should the patient have received two bottles?

Liquid cannot be split open to give exact amount and the error is on the side of more rather than give the patient less meds than required by the doctor. Just a side note, one refill is allowed. Thank you.

 NASAL SPRAY CALCULATION OF QUANTITY by: Dmom You are correct in your calculation. If you use 4 sprays daily as prescribed, a bottle of Fluticasone Propionate nasal spray 50 MCG will not last 30 days. We have been dealing with this problem for 6 months now for my husband. I don't understand how a pharmaceutical company calculates that the quantity is correct, that there is supposedly 120 metered sprays in a .54 oz bottle when there is 60 metered sprays in a .34 oz bottle. It certainly seems logical that if you double the number of metered sprays from 60 to 120 you would also have to double the contents of the bottle from .34oz to .68 oz. You are coming out .14oz short to finish a 30 day period. We have to buy Fluticasone Propionate nasal spray 50 MCG over the counter to finish the month. Anonymous needs to recalculate his or her findings as does the pharmaceutical companies.
