Hello,
Yes,you can cut the zyrtec tablet in two and it will amount to 5 mg.But it is subtherapeutic dose for adults.5mg is the therapeutic dose of children and not adults.
Hope it helps.Take care and pls do keep me posted on how you are doing.
You can buy the Children's Zyrtec, they are only 5 mg
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.
