Bottom Line

Allegra Adult 24HR Non-Drowsy Antihistamine is effective for many, particularly for long-term and non-drowsy allergy relief. However, potential psychological side effects warrant caution, especially for sensitive users. Its cost and variability in effectiveness could be a dealbreaker for some, but it's worth considering when other options aren't addressing your needs sufficiently. Do weigh it against cheaper OTC alternatives like Claritin or Zyrtec, especially for a less expensive and potentially effective solution.
