math calculations with nasal spray (1)

What are the total quantity and the total days supply for the following Rx: Omnaris nasal spray 2 sprays each nostril qam disp: 1 ------------------------------------------------------------ The doctor has prescribed Omnaris nasal spray. Each bottle has 12.5 grams and the contents of one bottle provide 120 metered actuations. The total quantity to be dispensed is either 12.5 g or 13 g depending on the pharmacy computer system. In this case, the pharmacist will dispense one bottle. The sig says: use 2 sprays in each nostril every morning The patient will use 4 sprays every morning. So, the total days supply will be 120 divided by 4 which is 30 days.

Calculate the total quantity and the total days supply for the following Rx: Rhinocort spray ii/nostril bid ------------------------------------------------------------ The doctor has prescribed Rhinocort Aqua 32 mcg nasal spray. The bottle has 8.6 grams of medicine and provides 120 metered sprays. The sig says: use 2 sprays in each nostril twice daily The doctor did not state the quantity, but the pharmacist will dispense one bottle. So, the total quantity to be dispensed is either 8.6g or 9g depending on the pharmacy computer system. The sig indicates that the patient will use 2 sprays * 2 noses * 2 daily. In other words, the patient will use 8 sprays per day. Now, the total days supply will be 120 sprays divided by 8 sprays which is 15 days.

Calculate the total quantity and the total days supply for the following Rx: Flonase 1 spray each nose bid 1 bottle ------------------------------------------------------------ The doctor has prescribed Flonase nasal spray (120 metered sprays), but most pharmacists will dispense the generic version fluticasone nasal spray 16g with 120 metered sprays. The bottle has 16g and therefore the total quantity to be dispensed is 16g The sig says: use 1 spray in each nose twice daily Now, we need to calculate the total days supply. The patient uses 4 sprays per day. Then, the days supply will be 120 sprays divided by 4 sprays which is 30 days.

Calculate the total quantity and the total days supply for the following Rx: Flonase NS 2 sprays each nostril qd please, dispense 3 month supply ------------------------------------------------------------ The doctor has prescribed Flonase nasal spray, but most pharmacists will dispense the generic version fluticasone nasal spray 16g with 120 metered sprays. The total days supply is 90 days as stated by the doctor. The sig says: use 2 sprays into each nostril every day The patient will use 2 sprays * 2 noses which is 4 sprays per day. But, the doctor wants the patient to use the medication for 90 days. So, the patient will use a total of (4 * 90) sprays, that is, 360 sprays. If one bottle has 120 sprays, then three bottles have 360 sprays. In turn, the pharmacist will dispense 3 bottles that will last the patient 90 days. We know that 1 bottle has 16 grams and, in turn, 3 bottles have 48 grams. So, the total quantity to be dispensed is 48 g It is worth noting that some insurance companies may not want to pay for three bottles all at once. Some insurance companies may force the patient to get one bottle in the first month. Then, the second bottle in the second month and, finally, the third bottle in the third month. In this case, the total quantity prescribed would be 48g, but the total quantity dispensed would be 16g and the total days supply would be 30 days.
