Hospital prescription

I did the calculation for the hospital prescription for 3 months supplies. The following is the method I used to get to the quantities to be dispensed.

For codeine phosphate, since it is administered four times a day, hence, in a week, it is 28 tablets. Then 3 months is equivalent to 3 x 4 weeks = 12 weeks. Therefore, the total quantities to be dispensed for codeine phosphate is 12 x 28 tablets = 336 tablets.

Since the pack comes in size of 28 tablets per pack. Therefore, 12 packs of 28 tablets of codeine phosphate were dispensed.

For naproxen, twice a day administration in a week is equivalent to 14 tablets. Since the pack comes in 56-tab pack (14 x 4 weeks), therefore, 3 packs were dispensed.

For lansoprazole, once a day in a week is 7 capsules. The pack comes in 28-tab pack; therefore, 3 packs were dispensed.
