Upsides
  • It doesn't cause daytime drowsiness unlike other antihistamines.
  • Side-effects are mild, if any at all.
  • Available over-the-counter without a prescription.
  • It provides quick relief of allergy symptoms for both children and adults.
  • It doesn't interfere with how a lot of other medicines work.
  • 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.
Downsides
  • It's not the best choice if you have persistent, daily allergy symptoms.
  • It's not recommended for children less than 2 years old.
  • 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.
