Frequently Asked Questions

What if the answer is not a whole tablet?

Only scored tablets should be split, and modified-release or coated tablets must never be broken.

Should the total be rounded up when dispensing?

Yes. Dispensed quantities are rounded up to whole tablets so the course can be completed.
