Depends: Claritin (loratadine) 10 mg is dosed once a day.

How much time does it take Claritin (loratadine) to work?

Who knows: Work for what? Claritin supposedly starts working within 90 minutes. But Claritin is also the weakest binding antihistamine sold over the counter. Personally, I feel Claritin is a waste of money. Use a stronger antihistamine like fexofenadine or Cetirizine which cause minimal to no sedation. Use Benadryl (diphenhydramine) only at nighttime because it can make you drowsy. ...Read more

How long does it take for Claritin (loratadine) to take effect on hives??

3 days to reach peak: Claritin (loratadine) (loratidine) takes 3 days to reach a steady state, so it could take that long for it to work on hives. Other non-drowsy antihistamines are a better choice: Allegra (fexofenadine) reaches peak effect within 2 hours and Zyrtec (cetirizine) reaches peak effect in 1-2 hours.
