First, and most obvious, it's Claratyne, not Claritin, which is just amusing.
Second, it's 12 hour because Australia apparently doesn't have Claratyne-D in 24 hour.
Third, there are only 6 tablets. There were no 15 packs or 30 packs.
So that's 3 days I can buy at a time, instead of 15. Somehow I can't see this as a long term solution. Hmmm...
