Upsides
  • Allegra (fexofenadine) is effective at reducing symptoms for seasonal allergies and chronic hives without significant drowsiness, unlike Benadryl.
  • Approved for kids aged 6 months or older.
  • Allegra (fexofenadine) comes in many forms, like tablet, liquid, and quick-dissolving tablet.
  • Dimetapp Cold And Allergy (Phenylephrine / Brompheniramine) is a combination medicine with a decongestant and an antihistamine that's helpful in treating nasal symptoms related to cold and allergy.
  • Brompheniramine (the antihistamine) is useful for itchy eyes, runny nose, or constant sneezing.
  • Phenylephrine (the decongestant) is good for relieving congestion.
Downsides
  • Allegra (fexofenadine)'s effectiveness can wear off over time.
  • The dose needs to be adjusted for people with kidney problems.
  • If you don't really need both of the medications in this combination, you'd be taking extra medicine and might have extra side effects for no reason.
  • Brompheniramine (the antihistamine) can cause dizziness, drowsiness, dry eyes/mouth, and constipation.
  • Phenylephrine (the decongestant) doesn't last as long as other oral decongestants like pseudoephedrine, but can cause jitteriness.
  • The two medications in this medicine can somewhat work against each other, with one making you sleepy and the other making you jittery.
