Oral Solid Medications (cont.)
• Scored tablets– Score allows the tablet to be divided
when smaller doses are ordered.
• Most often, scored tablets divide into halves.
• Some divide into thirds or quarters.
![Page 7: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/7.jpg)
Calculating Dosages –Oral Solid Medications
Rule 13-1Rule 13-1
Always question and/or verify when your calculation indicates to give a portion of a tablet when the tablet is not scored.
Never attempt to break a tablet that is not scored.
![Page 8: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/8.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Rule 13-2 Rule 13-2 Question and recheck any calculation that indicates that you should administer more than three tablets or capsules.
![Page 9: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/9.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Rule 13-3 Rule 13-3 Follow these steps when determining the amount of medication to administer to a patient:
Step A Convert
Step B Calculate
Step C Think! . . . Is It Reasonable?
If necessary, recheck calculation.

Calculating Dosages –Oral Solid Medications (cont.)
The order is to give the patient 15 mg mirtazapine PO now.
On hand: 30 mg scored tablets
Calculate the correct amount of medication to administer using method of choice.
![Page 11: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/11.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
H = 30 mg ; Q = 1 scored tablet; D = 15 mg
Step A Convert
No conversion is necessary.
![Page 12: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/12.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Step B Proportion H/Q = D/A or H:Q = D:A
30 mg/1 tab = 15 mg/A
30 x A = 1 tab x 15
30A/30 = 15 tab/30
A = 0.5 tab = 1/2 tab
![Page 13: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/13.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Step B Dimensional analysis
A = Q/H x D/1
A tab = 1 tab/30 mg x15 mg/1
A tab = 15 tab/30
A tab = 0.5 tab = 1/2 tablet
![Page 14: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/14.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Step B Formula Method
15mg/30 mg x 1 tab = A
15 tab/30 = A
0.5 tab = 1/2 tablet = A

![Page 15: Oral Solid Medications Solid oral medications come in several forms. –Tablets –Caplets –Capsules –Gelcaps.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649cea5503460f949b52c7/html5/thumbnails/15.jpg)
Calculating Dosages –Oral Solid Medications (cont.)
Step C Think! . . . Is It Reasonable?
15 mg is one-half of 30 mg, so 1/2 tablet is an appropriate answer.
Tablets are scored, so 1/2 tablet can be given.
