How To Take Claritin
Hive treatment: Hives can be acute, lasting less than 6 weeks or chronic lasting greater than 6 weeks, (possibly even for years). Antihistamines might control hives but could be needed long-term.

See an allergist to help find the underlying cause if your pcp fails to discover a trigger. ...Read more
Up to 1 hour: Claritin (loratadine) 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.

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. If you see no benefit at all within 5 hours of taking these, they probably will not work for you. ...Read moreSee 2 more doctor answers
