... Claritin-D became available over the counter. As I have a great prescription drug plan, (3 months for $5), I have been trying to find a prescription replacement (primarily for allergy/post-nasal drip due to allergies), or, a less expensive (than Claritin-D 12-hour) OTC. How good is this stuff, and, do you feel it works as well, or better, than Claritin-D?
