What key warnings should I know about before taking this medicine?

  • There is a risk of stroke with use of phenylpropanolamine. The Food and Drug Administration is asking drug companies to stop making products containing phenylpropanolamine.


What is this medicine used for?

  • This medicine relieves symptoms (runny nose, sneezing, throat irritation and itching; watery, irritated, itchy, red eyes) from allergies.
  • Long-term nasal congestion and headache are treated by phenylpropanolamine.


How does it work?

  • Chlorpheniramine, if taken before coming in contact with the material that causes the allergy, blocks the allergic reaction by minimizing/preventing the body's reaction to the allergen.
  • Phenylpropanolamine shrinks swollen nasal tissue and opens up passages. Sinus drainage is increased by this.


How is it best taken?

  • Take with or without food. Take with food if this medicine causes an upset stomach.
  • This medicine is most effective if started before contact with the allergen. Take at least 1-3 hours before.
  • Swallow sustained-release capsule/tablet whole. Do not chew, break, or crush.
  • A liquid (syrup) is available if you cannot swallow pills. Those who have feeding tubes can also use the liquid. Flush the feeding tube before and after medicine is given.

What do I do if I miss a dose?
