It means you take it as you need it, not necessarily twice a day or three times a day.

It just means when it is needed.
p.r.n. = when necessary (from "pro re nata," for an occasion that has arisen, as circumstances require, as needed)
For instance, you would take headache tablets p.r.n. because you only need them when you have a headache. - but then you would follow the instructions on the packet.
If you're not clear about when to take it, you should call your pharmacist and ask them to clarify it for you.
a.c. = before meals (from "ante cibum," before meals)
ad lib: use as much as one desires (from "ad libitum")
b.i.d. = twice a day
caps = capsules
da or daw = dispense as written
g (or gm or GM) = gram
gtt. = drops (from "guttae," drops)
h. = hour
mg = milligram
ml = milliliter
p.c. = after meals (from "post cibum," after meals)
p.o. = by mouth, orally (from "per os," by mouth)
p.r.n. = when necessary (from "pro re nata," for an occasion that has arisen, as circumstances require, as needed)
q.d. = once a day (from "quaque die," once a day)
q.i.d. = four times a day (from "quater in die," 4 times a day)
q._h.: If a medicine is to be taken every so-many hours (from "quaque," every and the "h" indicating the number of hours)
q.h. = every hour
q.2h. = every 2 hours
q.3h. = every 3 hours
q.4h. = every 4 hours
t.i.d. = three times a day (from "ter in die," 3 times a day)
ut dict. = as directed (from "ut dictum," as directed)
I hope this helps.....

Pro re nata (p.r.n.)
This Latin term, which is frequently used in medicine and pharmacy, means "occasionally" or "according to circumstances".
