math calculations with ear solution

What are the total quantity and the total days supply for the following Rx: Zinotic 3 drops L ear tid x 7 days ------------------------------------------------------------ The doctor has prescribed Zinotic ear drops (otic solution). The regular bottle contains 15 mL of solution and therefore the total quantity to be dispensed is 15mL The sig says: instill 3 drops in the left ear three times daily for seven days The patient will use 3 drops three times daily, that is, the patient will use 9 drops per day. Now, we need to calculate the total days supply. Assume 1 mL = 20 drops and then 15 mL = 300 drops The total days supply will be 300 drops divided by 9 drops which is 30 days. It is worth noting that some pharmacists may assume 1 mL = 15 drops.

What are the total quantity and the total days supply for the following Rx: Floxin otic singles 1 bid x 10 days ------------------------------------------------------------ The doctor has prescribed Floxin otic singles solution. The box comes with 20 single-dispensing containers. There are 10 pouches of 2 singles. In other words, there are 20 singles. Note that singles mean containers. 1 single = 0.25 mL and then 20 singles = 5 mL So, the box has 5 mL The sig says: use one single (container) in the affected ear(s) twice daily for 10 days The patient will use 2 singles daily for 10 days, that is, the patient will use 20 singles. In this case, the pharmacist will dispense the whole box. So, the total quantity to be dispensed is 5 mL The total days supply is 10 days as stated by the doctor.

What are the total quantity and the total days supply for the following Rx: Vosol HC otic solution disp: 1 bottle 5 gtt qid for 1 week ------------------------------------------------------------ The doctor has prescribed the brand-name drug Vosol HC otic solution, but the pharmacist will very likely dispense the generic version Acetic Acid and Hydrocortisone otic solution. The doctor wants the pharmacist to dispense one bottle. The bottle has 10 mL of solution.

What are the total quantity and the total days supply for the following Rx: Cortane-B aqueous otic soln 10mL 4 gtt L ear q 8 h x5days ------------------------------------------------------------ The doctor has prescribed Cortane-B aqueous ear drops.

The total quantity to be dispensed is 10 mL The sig says: instill 4 drops in the left ear every 8 hours for 5 days The patient will use 4 drops three times daily, that is, the patient will use 12 drops per day. Now, assume 1 mL = 20 drops and then 10 mL = 200 drops The total days supply will be 200 drops divided by 12 drops which is 16 days. It is worth noting that some pharmacists may assume 1 mL = 15 drops. It is also worth noting that some pharmacists may dispense Zotane HC aqueous otic drops.

What are the total quantity and the total days supply for the following Rx: Domeboro otic #1 4 gtt au q6h ------------------------------------------------------------ The doctor has prescribed Domeboro otic solution, but this drug has been discontinued. In turn, the pharmacist will dispense the generic version Acetic Acid in Aqueous Aluminum Acetate Otic Solution. The bottle size is 60mL The doctor wants the pharmacist to dispense one bottle. Then, the total quantity to be dispensed is 60 mL The sig says: instill 4 drops in each ear every six hours The patient will use 4 drops * 2 ears * 4 daily, that is, the patient will use 32 drops per day. Now, assume 1 mL = 15 drops and then 60 mL = 900 drops The total days supply will be 900 drops divided by 32 drops which is 28 days. It is worth noting that some pharmacists may assume 1 mL = 20 drops.

What are the total quantity and the total days supply for the following Rx: Antipyrine/Benzocaine otic solution disp: 10 mL 1 every 2 to 3 hours prn for earache ------------------------------------------------------------ The doctor has prescribed an otic solution. This medicine is usually used for children with ear infection and it comes with a dropper. The total quantity to be dispensed is 10 mL as stated by the doctor. The sig says: instill one dropperful in ear canal every 2 to 3 hours as needed for earache Assuming that the patient will use the drug into both ears. Then, we can say that the maximum amount is 1 drop in both ears 12 times daily, that is, the patient may use up to 24 drops daily. Now, we need to convert 10 mL into drops. If 1 mL = 15 drops, then 10 mL = 150 drops The total days supply will be 150 divided by 24 which is 6 days. It is worth noting that some pharmacists may assume 1 mL = 20 drops.

Calculate the total quantity and the total days supply for the following Rx: A/B Otic Drops 4 gtt ad tid x5d ------------------------------------------------------------ The doctor has prescribed Antipyrine/Benzocaine otic solution. This medicine is usually used for children with ear infection. The sig says: instill 4 drops into right ear three times daily for 5 days The patient has to use 4 drops * 3 daily, that is, the patient has to use 12 drops daily. The patient will use 12 drops during 5 days, that is, the patient will use 60 drops total. Now, we need to convert 60 drops into mL Assume that 1 mL = 15 drops x / 60 drops = 1 mL / 15 drops x = (60 * 1) / 15 x = 4 mL So, the patient will use 4 mL total. But, the regular size of this medication is 10mL and therefore the total quantity to be dispensed is 10mL even though the patient will only use 4mL The total days supply is 5 days as stated by the doctor. It is worth noting that A/B Otic Solution may also be used by adults and comes in packages containing 10mL and 15mL It is also worth noting that some pharmacists may assume 1 mL = 20 drops.

If 1 mL = 15 drops, then 15 mL = 225 drops The total days supply will be 225 divided by 24 which is 9 days. It is worth noting that some pharmacists may assume 1 mL = 20 drops.

Calculate the total quantity and the total days supply for the following Rx: Auralgan otic solution 2 gtt au q 4 h prn ------------------------------------------------------------ The pharmacist will dispense the newly formulated Auralgan otic solution. This new formulation is used not only for ear pain, but also for ear infection.

So, the patient will use 24 drops per day. The regular size of this medicine is 15 mL So, the total quantity to be dispensed is 15 mL Now, we need to convert 15 mL into drops. Assume 1 mL = 15 drops and then 15 mL = 225 drops The total days supply will be 225 divided by 24 which is 9 days. It is worth noting that some pharmacists may assume 1 mL = 20 drops.
