Intal (Cromolyn)

Prescription or OTC

Foradil (formoterol)

Prescription only
Relieves nasal allergy symptoms.

Intal (Cromolyn) is a good option to relieve nasal allergy symptoms when antihistamines aren't working. Good choice for pregnant women.

Controls chronic obstructive pulmonary disease (COPD).

Foradil (formoterol) is good for controlling and preventing chronic obstructive pulmonary disease (COPD) symptoms, but it's not a rescue inhaler and requires a jet nebulizer machine.

Upsides
  • Treats nasal allergy symptoms.
  • Most people don't have many side effects since it works in the nose and doesn't affect the rest of your body.
  • It's a good option for pregnant women. Can also be used for kids 2 years and older.
  • Doesn't make you drowsy or dizzy.
  • No prescription is needed.
  • Foradil (formoterol) works well to control chronic obstructive pulmonary disease (COPD) and can start working in as few as 5 minutes.
  • Taking Foradil (formoterol) into the lungs has fewer side effects than taking a pill by mouth.
  • Using a jet nebulizer is easier to use than a handheld inhaler, especially for children.
Downsides
  • Needs to be used regularly for at least a week to see any good effects.
  • Can have an unpleasant smell or taste.
  • Can cause headaches, or burning and stinging in your nose.
  • Depending on your insurance, Foradil (formoterol) can be more expensive than medicines delivered through an inhaler.
