How do Claritin-D and Claritin, and Allegra-D and Allegra differ from each other?
The biggest difference between Claritin-DŽ and
ClaritinŽ (loratadine) is
that ClaritinŽ is only an antihistamine. Claritin-DŽ is both a decongestant and an
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.
