If you have allergies that affect your eyes, your nose, your chest, your breathing or your sight � Allegra D is the medication that is going to treat all of these symptoms to help you lead a more normal life.
Allegra D Usage
Allegra D is an antihistamine, nasal decongestant used to relieve allergy symptoms such as watery, itchy, red eyes; sneezing, runny nose, itchy throat. Allegra (Fexofenadine) is also used for certain cases of itching skin (chronic idiopathic urticaria).
Allergies are often a seasonal problem that you can be prepared for when you have Allegra D on hand. As the allergy season approaches be sure to keep your own supply of Allegra D on hand and you will be able to sleep, play and work easier.
One thing to keep in mind when using Allegra D is that you shouldn’t take an antacid like tums, rollaid, or other stomach antacids before taking Allegra D. The antacids are going to counter act the effect of Allegra D on your system.
Always take just one dose of Allegra D, if you forget to take a pill, just skip it and continue on with the next scheduled dosage. Allegra D will provide you relief up to twelve hours a day in some cases.
How To Take Allegra
Take Allegra by mouth as directed, usually twice a day. Allegra may be taken with food or milk if stomach upset occurs. Do not take antacids containing aluminum and magnesium within 2 hours of taking Allegra.
Allegra-D relieves your most frustrating allergy symptom: congestion. That’s because it combines the proven seasonal allergy relief of Allegra with a powerful decongestant.
More good news: Allegra-D is fast acting. A study shows that patients taking Allegra-D feel significant relief from nasal congestion at just 60 minutes.
Allegra comes in different formulations, offering you relief from most of your seasonal allergy symptoms. So when you’re suffering from seasonal allergy symptoms without congestion choose Allegra. But when congestion is a problem, choose Allegra-D � and don’t let congestion frustrate you another day.
Allegra Side Effects
Nausea, stomach upset, menstrual cramps, fatigue, or cold symptoms may occur. If these effects continue or become severe, inform your doctor. Tell your doctor immediately if any of these highly unlikely but very serious side effects occur: dizziness, fainting, irregular heartbeat. Although drowsiness is uncommon at usual Allegra doses under normal circumstances, be aware that this medication may have such an effect before engaging in activities requiring alertness. If you notice other effects not listed above, contact your doctor or pharmacist.
ALLEGRA-D is contraindicated in patients with known hypersensitivity to any of its ingredients.
Due to its pseudoephedrine component, ALLEGRA-D is contraindicated in patients with narrow-angle glaucoma or urinary retention, and in patients receiving monoamine oxidase (MAO) inhibitor therapy or within fourteen (14) days of stopping such treatment (see Drug Interactions section). It is also contraindicated in patients with severe hypertension, or severe coronary artery disease, and in those who have shown hypersensitivity or idiosyncrasy to its components, to adrenergic agents, or to other drugs of similar chemical structures. Manifestations of patient idiosyncrasy to adrenergic agents include: insomnia, dizziness, weakness, tremor, or arrhythmias.
Precautions for Allegra
Before taking Allegra, tell your doctor if you have: kidney disease, heart disease, any allergies. Do not take Allegra for several days before any allergy testing since test results can be affected. Limit alcohol intake, as it may aggravate drug side effects. Allegra should be used only if clearly needed during pregnancy. Discuss the risks and benefits with your doctor. It is unknown if this drug is excreted into breast milk. Consult with your doctor before breast-feeding. Caution is advised when this drug is used in the elderly.
Due to its pseudoephedrine component, ALLEGRA-D should be used with caution in patients with hypertension, diabetes mellitus, ischemic heart disease, increased intraocular pressure, hyperthyroidism, renal impairment, or prostatic hypertrophy. 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.
Tell your doctor of any nonprescription or prescription medication you may use, especially of drugs that may affect the heart rhythm (QTc prolongation) such as: cisapride, dofetilide, certain quinolone antibiotics (e.g., moxifloxacin), sotalol, amiodarone, phenothiazines (e.g., thioridazine), procainamide, quinidine, “water pills” (diuretics such as furosemide or hydrochlorothiazide). Do not start or stop any medicine without doctor or pharmacist approval.
Fexofenadine hydrochloride and pseudoephedrine hydrochloride do not influence the pharmacokinetics of each other when administered concomitantly.
Fexofenadine has been shown to exhibit minimal (ca. 5%) metabolism. However, co-administration of fexofenadine with ketoconazole and erythromycin led to increased plasma levels of fexofenadine. Fexofenadine had no effect on the pharmacokinetics of erythromycin and ketoconazole. In two separate studies, fexofenadine HCl 120 mg BID (twice the recommended dose) was co-administered with erythromycin 500 mg every 8 hours or ketoconazole 400 mg once daily under steady-state conditions to normal, healthy volunteers (n=24, each study). No differences in adverse events or QTc interval were observed when subjects were administered fexofenadine HCl alone or in combination with erythromycin or ketoconazole. The findings of these studies are summarized in the following table.
ALLEGRA-D tablets (pseudoephedrine component) are contraindicated in patients taking monoamine oxidase inhibitors and for 14 days after stopping use of an MAO inhibitor. Concomitant use with antihypertensive drugs which interfere with sympathetic activity (eg, methyldopa, mecamylamine, and reserpine) may reduce their antihypertensive effects. Increased ectopic pacemaker activity can occur when pseudoephedrine is used concomitantly with digitalis.
Care should be taken in the administration of ALLEGRA-D concomitantly with other sympathomimetic amines because combined effects on the cardiovascular system may be harmful to the patient
