Benzotropine 62.5 mcg by mouth every 4 hours. Available dosage is 0.25 mg tablets. How many tablets should be given per dose?

The dose is determined by matching the prescribed amount to the strength of the available tablet using unit conversion. The order is 62.5 mcg, which equals 0.0625 mg. Each tablet provides 0.25 mg (250 mcg). To find how many tablets are needed, divide the dose by the tablet strength: 0.0625 mg ÷ 0.25 mg = 0.25. So, a quarter of a tablet is required to deliver 62.5 mcg. A quarter tablet corresponds to 62.5 mcg (since 1/4 of 250 mcg is 62.5 mcg). Using more tablets would give higher doses (0.5 tablet would be 125 mcg, 1 tablet would be 250 mcg, etc.), which are not correct for this order. In practice, always ensure the tablet can be accurately divided; if not, a different strength or dosage form may be necessary.
