Buying advice

When choosing an allergy medicine, consider your primary symptoms (sneezing, congestion, itchy eyes). Antihistamines like Zyrtec, Claritin, or Allegra work well for sneezing and itching, while nasal sprays like Flonase or Nasacort target congestion. For fast relief of severe symptoms, Benadryl works but causes drowsiness. If you need a non-drowsy option during the day, choose Claritin or Allegra. Always check for interactions with other medications and consult a doctor for children or chronic conditions.
