Question

How do Claritin-D and Claritin, and Allegra-D and Allegra differ from each other?

Answer

The biggest difference between Claritin-DŽ and ClaritinŽ (loratadine) is that ClaritinŽ is only an antihistamine. Claritin-DŽ is both a decongestant and an antihistamine (pseudoephedrine). Allegra-DŽ and AllegraŽ (fexofenadine) have the same difference as ClaritinŽ and Claritin-DŽ. Allegra-DŽ and Claritin-DŽ should be used when allergy symptoms include a stuffy nose because decongestants help dry out nasal congestion. All of these products are typically free of side effects, but the decongestant pseudoephedrine can result in insomnia. If you have high blood pressure, an overactive thyroid or an enlarged prostate consult your doctor before taking pseudoephedrine-containing medicines like Claritin-DŽ and Allegra-DŽ.

ClaritinŽ and AllegraŽ are available over-the-counter. Claritin-DŽ and Allegra-DŽ are available behind-the-counter because they contain pseudoephedrine. Check with a pharmacist or physician before using any new medication or drug.
