Upsides
  • One of the best over-the-counter options to clear stuffy nose and help you breathe better.
  • Clears nasal congestion better than other decongestants like phenylephrine.
  • Can be helpful in relieving congestion-related headaches and pressure in your ears.
  • Available in regular and extended release forms.
  • 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
  • Pseudoephedrine (a decongestant) can make your heart race or make you feel anxious and restless.
  • It can affect the quality of your sleep, so you can't take it too close to going to bed.
  • Can raise blood pressure so check with your doctor before using it if you have high blood pressure or other heart conditions.
  • Sudafed (Pseudoephedrine) isn't as effective after using it for more than 4 days straight.
  • Need to show a photo ID to buy it in the drugstore and there is a limit on how much you can buy each visit.
  • 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.
