What is the active ingredient in Fexofenadine?
The active ingredient in Fexofenadine tablets is:
- Fexofenadine hydrochloride (120mg or 180mg)
How does Fexofenadine work?
Fexofenadine works by blocking histamine, a chemical released during an allergic reaction. Histamine typically binds to receptors in different tissues, causing symptoms like itching, sneezing, runny nose, and watery eyes. By preventing histamine from binding to these receptors, Fexofenadine helps reduce these symptoms, offering relief without causing drowsiness, unlike some older antihistamines.
Does Fexofenadine interact with other medications?
Always inform your doctor or pharmacist if you are taking, have recently taken, or plan to take any other medicines. Some important interactions include:
- Apalutamide (used for prostate cancer): This may reduce the effectiveness of Fexofenadine.
- Indigestion remedies containing aluminum and magnesium: These can decrease the absorption of Fexofenadine. It is recommended to wait at least 2 hours between taking Fexofenadine and any indigestion remedies.
Always follow your healthcare provider's advice when taking multiple medications.

What is Fexofenadine?
Fexofenadine is an antihistamine medication designed to help relieve allergy symptoms, such as those from hay fever (allergic rhinitis) and hives (urticaria). It works by blocking histamine, a chemical that triggers allergic reactions like sneezing, itching, a runny nose, and watery eyes. As a second-generation antihistamine, it is less likely to cause drowsiness than older alternatives like diphenhydramine. Fexofenadine is available in various forms, including tablets, capsules, and oral suspension.
