What ingredients are in Allegra-D?
Allegra-D is an “allergy + congestion” brand that combines an oral antihistamine with a decongestant. The key drug ingredients are:
- Fexofenadine (an antihistamine)
- Pseudoephedrine (a decongestant)
Why does Allegra-D have two drug ingredients?
The combination is designed to treat both:
- Allergy symptoms (like sneezing, runny nose, itching) from fexofenadine
- Nasal congestion from pseudoephedrine
Which Allegra-D strength should I look for?
Formulations vary by country and product version (for example, different mg strengths and whether it’s extended-release). To make sure you have the exact “ingredients” and amounts for your box, check the Drug Facts panel for the specific strength of:
- fexofenadine
- pseudoephedrine
If you share the exact product name (e.g., “Allegra-D 12 Hour” vs “Allegra-D 24 Hour”) and the mg strengths listed, I can tell you the precise ingredient amounts.
Are there any common “inactive ingredients” besides the drug ingredients?
Yes. Like most oral medicines, Allegra-D also contains inactive ingredients (excipients) such as fillers, coatings, and colorants. Those vary by formulation. The most reliable source is the inactive ingredient list on the Drug Facts label.
If you paste the Drug Facts “Inactive ingredients” line(s), I can help you interpret what they are for (for example, dyes or allergy-relevant excipients).
