Fexofenadine

Fexofenadine is an antihistamine medication, which affect the way that the body responds to stimuli like dust, pollen and dander. Exposure to certain stimuli can cause the body to respond with allergy-type systems. The cells in the lining of the eyes and nose produce and release a chemical called histamine when they encounter irritants like dust and pollen, leading to symptoms such as a runny nose, cough or watering eyes. Some people can also experience inflammation and soreness. Fexofenadine is an antihistamine, which means that it counteracts the effects of the naturally produced histamines in the body, reducing the risk of side effects. Although some antihistamines are available over the counter, Fexofenadine is often given on prescription. It is available in tablet form.

When is Fexofenadine used?

As with other antihistamines, Fexofenadine is used to relieve allergy symptoms such as runny noses, watery and itching eyes, and sneezing. In some cases, it can also assist with dryness and hives caused by allergic responses to stimuli such as dust and dander. Doctors and medical professionals often prescribe Fexofenadine for hay fever (allergic reaction to pollen), and itching and discomfort caused by dust.

Fexofenadine can also be used to treat urticaria in its chronic and acute forms. In a case of urticaria, itchy skin rashes developed, often triggered by an allergy or another unknown factor. If the rash lasts for more than four to six weeks, it is usually referred to as chronic, and you may be given a number of treatments to address it.

There are different strengths of Fexofenadine hydrochloride tablets currently available, including 30 mg, 120 mg and 180 mg. Your doctor or medical consultant may be able to give you advice on which strength you need. Higher strengths of Fexofenadine hydrochloride tablets are often recommended for chronic urticaria.

What dosages are there?
