What Is Allegra (Fexofenadine) ?

Allegra, the brand name of fexofenadine, is an antihistamine used to treat symptoms of hay fever and other seasonal allergies. It is an over the counter medication that helps reduce the effects of a natural chemical produced by your body called histamine. Histamine causes allergic symptoms such as runny nose, sneezing, itchiness, and watery eyes.

Allegra works for both adults and children. This medication is also used to treat hives and itchy skin caused by chronic idiopathic urticaria.

Allegra Prescription FAQs

How Does Allegra Work?

Allegra works by blocking a histamine receptor known as an H1 receptor. It may cause less drowsiness than other antihistamines and starts to take effect in about one hour.

What is the Typical Allegra Dosage?

Allegra was approved by the Food and Drug administration in 1995. It is available in several different dosages. It comes in tablet, oral disintegrating tablets, and oral suspension forms:

  • Tablets – 30mg, 60mg, and 180mg
  • Oral disintegrating tablets – 30mg (These pills contain 5.3mg of phenylalanine. Do not use this form if you have phenylketonuria.)
  • Oral Suspension – 30mg per 5mL

Your dose will depend on your weight and age. Make sure not to go over the recommended dosage for children and infants.

What is the Typical Allegra Dosage for Children?

For children, Allegra has been approved by the FDA for use in a 12-hour format in the following forms:

  • Children’s Allegra Orally Disintegrating Tablets – These are good for children 6 years old and up
  • Children’s Allegra Liquid Oral Suspension – These are good for children 2 years old and up.

Be sure to consult with your pediatrician or allergist before starting your child on Allegra.

What are the Benefits of Allegra?

Allegra gives you sinus pressure relief and reduces nasal congestion. It also helps with upper respiratory symptoms brought on by hay fever and seasonal allergies, and works to reduce allergic responses to indoor allergens such as pet dander and mold.

It also helps to relieve nasal congestion from the common cold and helps control symptoms of itchy nose and throat, watery eyes, sneezing, and a runny nose. This medication offers 24-hour relief and does not make you drowsy, offering you a daytime respite while you go about your day.

Although Allegra is not certified as gluten free, this medication does not contain any ingredients from wheat, oats, spelt, rye, whey, or barley. However, it does contain corn gluten in its pregelatinized starch, but it is not gliadin gluten for which some people have developed a sensitivity.

Allegra also does not contain possible allergens such as eggs, iodine, shellfish, soy, tree nuts, peanuts, casein, talc, soy, dairy, or lactose.

What are Considerations and Precautions of Allegra?

Talk to your doctor about precautions while taking Allegra and drinking alcohol. Combining alcohol and Allegra can cause drowsiness and dizziness. Also, certain juices may decrease the effectiveness of this medication, such as orange, apple, or grapefruit juice.
