Allegra helps clear up allergies within 1 hour of taking a dose and it stays strong for up to 24 hours. There are three different types of Allegra products: Allegra, Allegra-D, and Children’s tablets. The children’s tablet actually melts in your child’s mouth so they don’t have to try to swallow a huge tablet. It is always non-drowsy and in a good-tasting, orange cream flavor. It treats sneezing, running nose, itchy, watery eyes, and itchy nose or throats. There is also a children’s liquid version. Allegra works the same as the children’s version and treats the same symptom, except it is not flavored. Allegra-D is for allergy and congestion and sinus relief.
