Allergies: They do cause tiredness and drowsiness. I recommend its use in the evenings every day during allergy season. Check with your physician to see if fexofenadine is an alternative.

Yes: Try generic for Claritin (loratadine) or allegra.

Allegra (fexofenadine) causes the least amount of drowsiness. The true effective dose of claritin in 20mg but they sell as 10mg since the 20mg causes as much drowsiness as 10mg zyrtec.
