Allegra Use

Allegra is a non-sedating antihistamine that relieves seasonal allergy symptoms like runny nose, itching, watery eyes, and sneezing.

How Allegra works

Allegra relieves allergy symptoms by blocking the effect of histamines. Histamines are chemicals in your body that cause allergy symptoms.

How to take Allegra

Allegra is available in 60 mg and 120 mg tablets. For people 12 and older the normal recommended dose is one 60 mg or 120 mg tablet twice daily.

Allegra precautions

You should not take Allegra if you have retained urine, narrow angle glaucoma, severe high blood pressure, heart disease, or if you have taken MAO inhibitors (depression medication) within the last 14 days. If you experience an allergic reaction to Allegra such as difficulty breathing or swelling of the lips, tongue, or face, discontinue use and seek medical attention immediately. Do not take Allegra with antacids that contain aluminum or magnesium such as Rolaids, Magnesia, and/or Pepcid Complete. These antacids may decrease the effectiveness of Allegra.

What to tell your doctor

Before you begin taking Allegra, tell your doctor if you have a serious illness such as heart disease, kidney disease, or liver disease. Also, if you are pregnant or nursing talk to your doctor about potential risks to the fetus or baby.

Allegra side effects

Less serious side effects that may occur while you are taking Allegra include: headache, cold, coughing, back pain, flu, nausea, menstrual pain, insomnia, and/or drowsiness.
