How long should it take for my Claritin to work?

Up to 1 hour: Claritin can work relatively quickly in most people. That is, it usually works within 30 minutes. However, in some people it may take up to 60 minutes to have its full effect. If it is not working within that time, or if the duration of effect becomes less and less, seeing an allergy specialist for allergy testing would be recommended as other treatments may be more effective. ...Read more

How much time does it take Claritin 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 only at nighttime because it can make you drowsy. ...Read more
