Question

What do you write on the prescription when the dosage has to be taken after food?

(a) a.c.

(b) p.c.

(c) p.r.n.

(d) p.r.

The question was posed to me by my school teacher while I was bunking the class.

This is a very interesting question from Controlled Release Medication in division Controlled Release Medication of Drug Biotechnology

Answer 1

The correct answer is (b) p.c.

The best I can explain: P.c. means after food. That means the patient should take in the full stomach. When a doctor writes a.c. on prescription for a drug that means you should take it before food. P.r.n. means the drug can be taken as required. P.r means the dosage has to be given rectally.
