Upsides
  • This once-daily, single-pill combination conveniently treats congestion and other allergy symptoms.
  • It doesn't cause any daytime drowsiness unlike other antihistamines.
  • It doesn't require a prescription from your doctor.
  • Benadryl (Diphenhydramine) is often better than other antihistamines at treating allergy symptoms and hives.
  • It can provide quick relief of allergy symptoms for both kids and adults.
  • It makes you sleepy, so it'll help if your allergies are bothering you at night.
  • The effects wear off in 4 to 6 hours, so side effects don't last that long.

Downsides

  • It may interfere with how your other medicines work. Talk to your doctor or pharmacist before combining with other medicines.
  • Benadryl (Diphenhydramine) makes you more tired than Claritin, Allegra, or Zyrtec.
