Question

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

Answer

The biggest difference between Claritin-D® and Claritin® (loratadine) is that Claritin® is only an antihistamine. Claritin-D® is both a decongestant and an antihistamine (pseudoephedrine). Allegra-D® and Allegra® (fexofenadine) have the same difference as Claritin® and Claritin-D®. Allegra-D® and Claritin-D® 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. All of these drugs are available over-the-counter, but check with a pharmacist or physician before using any new medication or drug.
