About Allegra.

Allegra Dosage: An Introduction
The dose of Allegra (fexofenadine hydrochloride) your healthcare provider recommends will vary depending on a number of factors, including:

Your age
The severity of your symptoms
Other medical conditions you have
Other medications you are currently taking.

As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Allegra Dosage for Seasonal Allergies or Chronic Hives

Adults and Children 12 Years and Over
For adults and children 12 years old and over with seasonal allergies, the recommended Allegra dose is Allegra 60 mg twice a day or Allegra 180 mg once a day.

If you have kidney disease or are over age 65, your healthcare provider may start you on a lower dose of Allegra, such as Allegra 60 mg once a day.

Children 6 to 11
For children 6 to 11 years of age, the recommended Allegra dose is Allegra 30 mg twice a day. Children in this age group may need to take Allegra ODT 30 mg tablets (orally disintegrating tablets, which rapidly dissolve in the mouth) or Allegra oral suspension (liquid).

For children with kidney disease, a dose of 30 mg once a day is usually recommended.

Allegra (fexofenadine hydrochloride) is a prescription medication that has been licensed to treat a few conditions. The most common Allegra uses are:

Relief of seasonal allergy symptoms (hay fever)
Treatment of chronic (long-term) hives and itching.

Seasonal Allergy Symptoms
Seasonal allergies, also known as “hay fever” or “pollen allergy,” are among the most common kinds of allergies. About 35 million Americans suffer from hay fever. Hay fever is caused by breathing in pollen from trees, grasses, or weeds that cause an allergic reaction. This can result in classic allergy symptoms.

Allegra is used to treat hay fever symptoms, including:

Sneezing
Runny nose
Itchy nose, or throat
Itchy, watery, or red eyes.

Allegra can be used to treat the symptoms of hay fever in adults and children six years of age and older.

Treating Chronic Hives Using Allegra
Chronic hives, known medically as “chronic urticaria,” cause blotchy, red, raised bumps (hives) and itching. In order to be diagnosed with chronic urticaria, a person must experience recurring hives and itching for at least six weeks.

Allegra is prescribed to decrease the itching and recurrence of the hives. It also treats their severity and duration. Allegra can be used to treat chronic hives in adults and children six years of age and older.

Before medicines are approved, they must go through several clinical studies in which thousands of people are given a particular medicine and are then compared to a group of people who were not given the medicine (these people took a sugar pill, or placebo). In these studies, side effects are always documented. As a result, it is possible to see which side effects occur, how often they appear, and how they compare to the group not taking the medicine. Side effects are then usually separated into those side effects that occur in more than 1 percent of people (common side effects) and those that occur in less than 1 percent of people (rare side effects).

Headaches (including migraines) were reported in up to 10.3 percent of adults taking Allegra once a day for allergies. Up to 7.2 percent of people taking a placebo reported a headache. These studies did not separate migraine headaches from other types of headaches.
