Are the OTC Zyrtec tablets or capsules? I take Benadryl myself. I don't know if you'll get the full benefits, but if they're too strong for you, then I don't see why you can't just use a pill splitter and cut tablets in half. I had to ask for a lower dosage for my Benadryl myself for the same reason. This is also what I read that I needed to do with kidney function issues. Mine are capsule form that I buy behind the pharmacy counter as a prescription. The insurance still won't cover them, but they're still cheaper to buy this way than buying them OTC.
