What is Fexofenadine?

Fexofenadine is an antihistamine used to alleviate allergy symptoms, including hay fever (allergic rhinitis) and hives (urticaria). It functions by blocking histamine, a chemical in the body responsible for triggering allergic reactions such as itching, sneezing, a runny nose, and watery eyes.

As a second-generation antihistamine, Fexofenadine is less likely to cause drowsiness compared to first-generation antihistamines like diphenhydramine.

What is the active ingredient in Fexofenadine?

The active ingredient in Fexofenadine tablets is:
  • Fexofenadine hydrochloride (120mg or 180mg)
 

What is Fexofenadine used for?

Fexofenadine tablets are primarily used to relieve allergy-related symptoms, including:
  • Hay fever (allergic rhinitis): Symptoms such as sneezing, a runny or itchy nose, nasal congestion, and itchy or watery eyes caused by allergens like pollen, dust mites, or pet dander.
  • Hives (urticaria): Itchy, raised welts on the skin that can appear suddenly, often triggered by allergens like certain foods, medications, or environmental factors.
Fexofenadine works by blocking histamine, a substance in the body responsible for allergic reactions and symptoms. By inhibiting histamine activity, Fexofenadine helps reduce symptoms such as itching, sneezing, a runny nose, and watery eyes.
 
 

How does Fexofenadine work?

Fexofenadine works by blocking the action of histamine, a chemical released by the body during an allergic reaction. Histamine binds to receptors in various tissues, causing symptoms like itching, sneezing, runny nose, and watery eyes. By inhibiting histamine from binding to these receptors, Fexofenadine reduces these allergic symptoms, providing relief without causing significant drowsiness, which is common with some older antihistamines.

How do you take Fexofenadine?

Always take this medication exactly as prescribed by your doctor. If you're unsure, consult your doctor or pharmacist.

For adults and children aged 12 years and over:

The recommended dose is one 120 mg tablet daily. Take your tablet with water before a meal. This medicine begins to relieve symptoms within 1 hour and provides relief for 24 hours.

If you take more Fexofenadine Tablets than recommended:

If you accidentally take too many tablets, contact your doctor or go to the nearest hospital emergency department immediately. Overdose symptoms in adults may include dizziness, drowsiness, fatigue, and dry mouth.

If you forget to take a dose:

Do not take a double dose to make up for a missed tablet. Simply take the next dose at the usual time as directed by your doctor.

Does Fexofenadine interact with other medicines?

Inform your doctor or pharmacist if you are currently taking, have recently taken, or may take any other medications. If you are taking apalutamide (used to treat prostate cancer), it may reduce the effectiveness of fexofenadine. Indigestion remedies containing aluminum and magnesium can interfere with Fexofenadine Tablets by reducing the amount of the drug absorbed. It is recommended to wait about 2 hours between taking Fexofenadine Tablets and any indigestion remedies.
