Allegra vs. Allegra-D

Key Differences

Allegra is primarily used to treat symptoms of seasonal allergies, such as sneezing, itchy eyes, and runny nose. Allegra-D combines the antihistamine effects of Allegra with a decongestant to also target nasal congestion and sinus pressure.

The key ingredient in Allegra is fexofenadine, which works by blocking histamine, a substance in the body that causes allergic symptoms. In Allegra-D, pseudoephedrine is added as a decongestant to reduce swelling in the nasal passages.

Allegra is often recommended for individuals who need relief from allergy symptoms without additional decongestant effects. Allegra-D, on the other hand, is better suited for those who also suffer from congestion related to allergies.

A significant difference is that Allegra can be purchased over the counter without restrictions. Allegra-D, due to its pseudoephedrine content, is often kept behind the pharmacy counter in many countries, including the United States.

Allegra is generally safe for long-term use with minimal side effects. Allegra-D, because of the decongestant, might not be suitable for individuals with certain health conditions like hypertension or heart disease.
