Upsides
  • Works to clear nasal congestion and helps you breathe better.
  • Helpful in relieving congestion-related headaches.
  • Has fewer side effects than other decongestants like pseudoephedrine.
  • It doesn't raise your blood pressure and heart rate as much, or cause as much trouble falling asleep.
  • Doesn't give you rebound congestion (worse symptoms when you stop taking it) like nasal spray decongestants do.
  • 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
  • Phenylephrine doesn't last as long as other decongestants like pseudoephedrine (Sudafed).
  • You shouldn't use it if you have high blood pressure.
  • Can make your heart race or make you feel anxious and restless.
  • Shouldn't use it before you want to sleep.
  • Not as effective after using it for 4 days in a row.
  • 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.
