Tablets have the following unique shape and identifiers: 30 mg tablets are round, bi-convex and have 03 on one side and a scripted “e” on the other; 60 mg tablets are oval, bi-convex and have 06 on one side and a scripted “e” on the other; and 180 mg tablets are oblong, bi-convex and have 018 on one side and a scripted “e” on the other.

Secondary to the pseudoephedrine component, fexofenadine HCl; pseudoephedrine HCl should be used with caution in patients with the following medical conditions:

• Hypertension
• Diabetes mellitus
• Ischemic heart disease
• Increased intraocular pressure
• Hyperthyroidism
• Prostatic hypertrophy
• Renal impairment (patients with decreased renal function should be given a lower initial dose (one tablet per day) because they have reduced elimination of fexofenadine and pseudoephedrine)

The safety of Allegra has not been established in pregnant women, therefore Allegra should not be used in women who are trying to get pregnant or in women who are pregnant. Women should not take Allegra while breastfeeding their infant because it is not known whether Allegra is excreted in the breast milk.

Allegra D provides effective relief from the symptoms of seasonal allergies including itchy, watery eyes; itchy palate; sneezing and runny nose.

So whether you suffer from allergies secondary to dogs, cats, pets, pollen, ragweed, dander, mildew, dust, mold, feathers, etc. Allegra D will provide relief.

Distinct from the current over-the-counter and many prescription antihistamines, Allegra D, provides relief without causing drowsiness. In fact, regulations require all antihistamines that cause drowsiness to caution users concerning the operation of a motor vehicle or heavy machinery. Allegra does not carry any such label. Therefore, with Allegra D you can continue your normal activities without feeling drowsy or tired.

Allegra D is an antihistamine that works by blocking the action on histamine, when antibodies latch onto mast cells, the mast cells release histamine, a chemical that causes blood vessels in the nose to dilate and leak fluid into surrounding tissue. This results in swelling, itching and nasal discharge. Allegra D blocks the release of histamine so these symptoms of watery eyes, itchy palate, sneezing, stuffiness, runny nose, etc. are significantly decreased.

A common question is what is the difference between Allegra and Allegra D? The difference is Allegra-D combines antihistamine with the nasal decongestant pseudoephedrine. The psuedoephedrine causes a narrowing of the blood vessels in the nose this leads to a clearing of the nasal congestion. This is why so many doctors prefer Allegra D over Allegra.

Fexofenadine hydrochloride, the active ingredient of ALLEGRA, is a histamine H1-receptor antagonist with the chemical name (±)-4-[1-hydroxy-4-[4-(hydroxydiphenylmethyl)-1-piperidinyl]-butyl]-(alpha), (alpha)-dimethyl benzeneacetic acid hydrochloride. It has the following chemical structure

ALLEGRA is indicated for the relief of symptoms associated with seasonal allergic rhinitis in adults and children 6 years of age and older. Symptoms treated effectively were sneezing, rhinorrhea, itchy nose/palate/throat, itchy/watery/red eyes.

ALLEGRA is indicated for treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in adults and children 6 years of age and older. It significantly reduces pruritus and the number of wheals.

Fexofenadine hydrochloride has a good safety profile in treating allergic rhinitis in children 6-24 months of age, researchers report in the December issue of the Annals of Allergy, Asthma, and Immunology.

“Allergic rhinitis (AR) is a common chronic condition and is estimated to affect up to 40% of children in some countries,” Dr. Frank C. Hampel, of Central Texas Health Research, New Braunfels, Texas, and colleagues write. “Antihistamines are an established first-line treatment for allergic rhinitis and are widely prescribed in infants for allergic symptoms.”

The researchers assessed the safety and tolerability of fexofenadine hydrochloride in children aged 6 months to 2 years in two studies, both multicenter, randomized, placebo-controlled, parallel-group trials. The mean duration of treatment was 8 days.

Altogether, 393 subjects were randomized to twice-daily fexofenadine hydrochloride, 15 or 30 mg, or placebo. All but one received treatment: fexofenadine 15 mg (n = 85); fexofenadine 30 mg (n = 108); and placebo (n = 199). Overall, 265 participants completed the study per protocol.

The incidence of treatment-emergent adverse events (TEAEs) was comparable between groups in the combined population — 48.2% in the placebo group, 40.0% in the fexofenadine 15 mg group, and 35.2% in the fexofenadine 30 mg group.

The most common TEAE was vomiting. Most TEAEs were unrelated to study medication. The TEAEs that were possibly related to study medication were mild to moderate in intensity.

“No clinical differences were observed between the fexofenadine treatment groups and placebo for any vital sign or any ECG variable,” Dr. Hampel and colleagues found. “No clinically meaningful differences were observed between the fexofenadine treatment groups and placebo for any of the physical examination results.”

They add: “To our knowledge, this is the first report to establish the safety and tolerability of fexofenadine at clinically relevant doses in children between 6 months and 2 years.”
