Is Claritin-D habit forming?

Loratadine, the primary ingredient in Claritin is Not knwon to be "habit forming". Pseudoephedrine on the other hand, can be in some cases, if the user is prone to "upper" "addiction". Pseudo is a a "precursor" to Ephedrine and Speed. But then again, ANYTHING can really be "habit forming" if you Allow it to be.

Short answer, as long as taking ONLY AS DIRECTED, and not taking too much pseudo, No. It is Not "habit forming".

Good luck and get better soon!
