math calculations with Cleocin oral solution

Calculate the total quantity and the total days supply for the following Rx: Cleocin 75mg/5mL sig: 300 mg q 6 h x 10 days ------------------------------------------------------------ The doctor has prescribed Cleocin pediatric 75mg/5mL oral solution. The total days supply is 10 days as stated by the doctor. The sig says: take 300 mg by mouth every six hours for 10 days Since this medicine is a liquid, we need to convert 300mg to mL by using the ratio 75mg/5mL x / 300 mg = 5 mL / 75 mg x = (300mg * 5mL) / 75mg x = 1500 mL / 75 x = 20 mL The final sig will say: take 20 mL by mouth every 6 hours for 10 days So, the patient will take 20mL four times daily for 10 days. In other words, the patient will take 20 * 4 * 10 which is 800mL But, this medicine is available in bottles of 100 mL If 1 bottle = 100 mL, then 8 bottles = 800 mL So, the total quantity to be dispensed is 800 mL In this case, the pharmacist will dispense 8 bottles of 100mL each. Do not refrigerate the reconstituted solution!!! It is worth noting that some pharmacists may dispense the generic version Clindamycin Palmitate 75mg/5mL oral solution.

Calculate the total quantity and the total days supply for the following Rx: Clindamycin 75/5 2 tsp tid x 7 days QS for 7 days ------------------------------------------------------------ If you check the inventory database, you will find that Clindamycin 75mg/5mL refers to Cleocin PED 75mg/5mL oral solution. So, the pharmacist will dispense either Cleocin PED 75mg/5mL oral solution or Clindamycin Palmitate 75mg/5mL oral solution. The total days supply is 7 days as stated by the doctor. The sig says: take 2 teaspoonsful by mouth three times daily for 7 days 1 teaspoonful = 5 mL and therefore 2 teaspoonsful = 10 mL The patient will take 10 mL * 3 daily * 7 days, that is, the patient will take 210mL total. This medicine is available in bottles of 100 mL If 1 bottle = 100 mL, then 2 bottles = 200 mL In this case, the pharmacist will dispense 2 bottles of 100mL each. So, the total quantity to be dispensed is 200 mL even though the sig directions indicate a total of 210mL Do not refrigerate the reconstituted solution!!!

Calculate the total quantity and the total days supply for the following Rx: Clindamycin 120mg sig: 120mg po q6h disp: QS x5d ------------------------------------------------------------ This medicine was actually prescribed for a child. The doctor has prescribed Clindamycin Pediatric. In this case, the pharmacist will dispense either Cleocin pediatric 75mg/5mL oral solution or Clindamycin Palmitate 75mg/5mL oral solution. The sig says: give 120 mg by mouth every six hours for 5 days Since this medicine is a liquid, we need to convert 120mg to mL by using Cleocin PED 75mg/5mL x / 120 mg = 5 mL / 75 mg x = (120 * 5) / 75 x = 8 mL The new sig will say: give 8mL by mouth every six hours for 5 days Notice that every six hours mean four times daily. In other words, the patient will take 8 * 4 * 5 which is 160mL But, this medicine comes in a bottle of 100mL Since the patient will take 160 mL, the pharmacist has to dispense two bottles of 100mL each. So, the total quantity to be dispensed is 200 mL The total days supply is 5 days as stated by the doctor. Now, the pharmacist could improve the directions for the patient. The final sig could say: give 8 mL by mouth every six hours for 5 days. Then, discard the remainder. Do not refrigerate the reconstituted solution!!!

Calculate the total quantity and the total days supply for the following Rx: Clindamycin 75mg/5mL 5 mL tid x 10 days ------------------------------------------------------------ If you check the inventory database, you will find that Clindamycin 75mg/5mL refers to Cleocin PED 75mg/5mL oral solution. So, the pharmacist will dispense either Cleocin pediatric 75mg/5mL oral solution or Clindamycin Palmitate 75mg/5mL oral solution. The total days supply is 10 days as stated by the doctor. The sig says: give 5 mL by mouth three times daily for 10 days In other words, the child will take 5mL * 3 daily * 10 days which means the child will take a total of 150mL. But, this medicine comes in a bottle of 100mL Since the patient will take 150 mL, the pharmacist has to dispense two bottles of 100mL each. So, the total quantity to be dispensed will be 200mL. In this case, we can rewrite the directions: give 5mL by mouth three times daily for 10 days only. Discard the remainder. Do not refrigerate the reconstituted solution!!!

Calculate the total quantity and the total days supply for the following Rx: Clindamycin 75/5 2 tsp po q8h for infections x 10 days ------------------------------------------------------------ If you check the inventory database, you will find that Clindamycin 75mg/5mL refers to Cleocin pediatric 75mg/5mL oral solution. In other words, the doctor has prescribed a pediatric oral solution. In this case, the pharmacist will dispense either Cleocin pediatric 75mg/5mL oral solution or Clindamycin Palmitate 75mg/5mL oral solution. The total days supply is 10 days as stated by the doctor. The sig says: give 2 teaspoonsful by mouth every eight hours for 10 days for infection In other words, the child will take 2 teaspoonsful three times daily for 10 days. We know that 1 tsp = 5 mL and, then, 2 tsp = 10 mL So, the child will take 10 mL three times daily, that is, the child will take 30mL per day. The total quantity to be dispensed will be 30mL * 10 days which is 300mL In this case, the pharmacist will dispense three bottles of 100mL each. Do not refrigerate the reconstituted solution!!!
