What is the Difference Between Allegra and Claritin?

🆚 Go to Comparative Table 🆚

Allegra and Claritin are both over-the-counter antihistamines used to treat allergy symptoms, but they have some differences in terms of their active ingredients, effectiveness, and side effects.

  • Active Ingredients: Allegra contains fexofenadine, while Claritin contains loratadine.
  • Effectiveness: Studies suggest that Claritin may be more effective than Allegra for allergic rhinitis, providing faster onset of action and more symptom relief. However, Allegra may provide more eye symptom relief and be more effective for wheal and flare reactions, which are allergic skin reactions.
  • Side Effects: Both Allegra and Claritin have generally mild side effects, including headache and nausea. Allegra has the lowest risk of sedation among all antihistamines, making it a preferred choice if sedation is a concern.
  • Drug Interactions: Allegra and Claritin interact with some of the same drugs, such as ketoconazole and erythromycin. However, Allegra can also interact with antacids, while Claritin can interact with amiodarone.

Both medications are second-generation antihistamines with a low risk of sedation and are considered safe and effective for most people. It is essential to consider your specific allergy symptoms, medical history, and potential drug interactions when choosing between Allegra and Claritin. Consult your healthcare provider for personalized advice on the most suitable allergy medication for you.
