For a prescription of Sulfasalazine (Azulfidine) 500 mg at 1.5g qid for 10 days, how many tablets should be dispensed?

To determine the total number of Sulfasalazine (Azulfidine) tablets required, it's essential to compute the total daily dosage and then multiply by the total number of days the medication is prescribed.

The prescription indicates a dosage of 1.5 grams (1500 mg) taken four times a day (qid). Therefore, the daily total dosage is:

1.5 g x 4 = 6 g per day, which is equivalent to 6000 mg.

The prescription is for a duration of 10 days. Thus, over 10 days, the total amount of Sulfasalazine required is:

6000 mg/day x 10 days = 60,000 mg.

Since each tablet of Sulfasalazine is 500 mg, we can calculate the number of tablets needed by dividing the total milligrams required by the milligrams per tablet:

60,000 mg ÷ 500 mg/tablet = 120 tablets.

Thus, the correct answer is 120 tablets, as that is the total needed to fulfill the prescribed course of treatment.
