To determine the total number of10 mg prednisone tabletsrequired to fill the prescription, let's break it down by daily dosing:

First 2 days→ 20 mgtwice daily(b.i.d) =40 mg per day

Total for 2 days:40 mg × 2 =80 mg

Next 2 days→ 20 mgonce daily=20 mg per day

Total for 2 days:20 mg × 2 =40 mg

Next 2 days→ 10 mgonce daily=10 mg per day

Total for 2 days:10 mg × 2 =20 mg

Final 2 days→ 5 mgonce daily=5 mg per day

Total for 2 days:5 mg × 2 =10 mg

Days 1–4:(20 mg doses) → Each 20 mg dose requirestwo 10 mg tablets

Total for these 4 days:(20 mg × 4 days) = 80 mg

Tablets required:80 mg ÷ 10 mg =8 tablets

Days 5–6:(10 mg doses) → Each day requiresone 10 mg tablet

Total for these 2 days:10 mg × 2 =20 mg

Tablets required:20 mg ÷ 10 mg =2 tablets

Days 7–8:(5 mg doses) → Each day requireshalf of a 10 mg tablet

Total for these 2 days:5 mg × 2 =10 mg

Tablets required:1 full tablet (split into halves for two doses)
