Wow! That was figuered out the LONG way!🤣🤣🤣

[TravelingYeti]

Yes but this didn't explain how to calculate with creams, gels, or liquids.

If I get a prescription for 200 tablets and take 1.5 tablets every 4 hours, then the days supply is 22 & 2/9 The computer will only take whole numbers. So should the pharmacist bill as a 22 day supply or 23? I told him that it is only a 22 day supply but he insists it is correct to round up to 23. Is this correct?

Why is the QTY NUMBER ON THE bottle label HIGHER THAN THE AMOUNT OF PILLS IN THE BOTTLE. The number on the label is QTY 150 when there are only 30 5mg pills in the bottle.

Can someone calculate this for me? Prescription: Suboxone Films 8mg/2mg. Place 1 and 1/8 films under the tongue once daily. Patient is given 30 films. How many days should the prescription last?

[JhaneTheLady]

I have a question.
My question on my paper says
"If 10 units are injected twice daily, how many days supply in 12 ml?"

Which formula would I need to use and how would I know to use that particular formula?

Days Supply = Quantity Dispensed / Daily Dose
OR
Quantity Dispensed = Daily Dose × Days Supply

My answer choices are
A. 6
B. 60
C. 120
D. 240

[calvinsFuntimeBounceHouse]

its a good system, i understand why you would show it this way because in this format you can expand it to the much harder systems, however youre forgetting KISS, the simplest way is best initially

aka: 50 pills. two pills per day.... 25

[sydneymanning]

do a video on how to calculate day supply if the quantity isnt given

[christy]

Every night I'm in bed at 12 I can't sleep pat 5am to save my life. Which my doctor has known about for the past 9years and has tried to fix but there's no use. Lol. Anyway not the issue at hand. So when the Dr writes the script at Every 4 hours please tell me the month supply. I need to know if I'm doing the right math equation.

[LinelleRobertson-izti]

45 pills taken every 4 hours equals how many day

[laneejones]

If my prescription says 4 a day starting on jan26 th when should I run out
