Allegra-D Medication Information
Allegra-D® (fexofenadine and pseudoephedrine) is a nonprescription drug approved for the treatment of seasonal allergies (hay fever). It is a combination product that contains both an antihistamine and a decongestant.
Even though this medication is available without a prescription, there are times when the drug's safety information should be discussed with your healthcare provider. For example, before treatment begins, tell your healthcare provider if you have:
- High blood pressure
- Urinary blockage or difficulty urinating
- Glaucoma
- Diabetes.
You should also tell him or her about all other medications you are taking to help minimize the risk of drug interactions.
