Fexofenadine Product Information
Fexofenadine is a highly effective antihistamine medicine used to treat the symptoms of seasonal allergic rhinitis, commonly known as hay fever. Sufferers of hay fever often exhibit symptoms including a runny nose, sneezing and red, itchy, and watering eyes.
How does Fexofenadine work?
Fexofenadine contains 120mg of the active ingredient fexofenadine hydrochloride, which blocks histamine H1 receptors in the body to prevent or reduce the symptoms caused by the release of histamines in response to an allergic reaction.
Histamines act as neurotransmitters and are released in the inflammatory response during an allergic reaction, causing a chain reaction that results in allergy symptoms.
How long does Fexofenadine last?
Fexofenadine lasts for up to 24 hours when taken as recommended. For continued hay fever symptom relief, it is recommended to take Fexofenadine daily following consultation with your doctor or pharmacist.
If you do miss a daily dose of Fexofenadine, do not compensate for the missed dose and take an extra dose (known as double dosing). Simply continue with your usual dosage schedule recommended by your doctor or pharmacist.
How do I take Fexofenadine?
Fexofenadine tablets are to be taken with water once daily before a meal. Fexofenadine can be taken as a one-off dose for relief from occasional hay fever symptoms.
For chronic, persisting symptoms, and/or in anticipation of a high pollen count or increased exposure to a particular allergen, you may be advised by your doctor or pharmacist to take Fexofenadine on a daily basis for an extended period of time.
Fexofenadine can also be taken alongside other non-prescription hay fever treatments such as nasal sprays and topical skin creams if necessary.
How much Fexofenadine can I take in a day?
For patients aged 18 and above, the recommended dose of Fexofenadine is one tablet per day.
Following consultation and guidance with your doctor or pharmacist, you may need to take Fexofenadine daily to treat chronic hay fever symptoms or on an ‘as needed’ basis if symptoms are infrequent.
How effective is Fexofenadine?
Fexofenadine is highly effective at relieving common hay fever symptoms, provided that the individual taking it adheres to the prescriber's instructions.
Fexofenadine has undergone thorough clinical trials, and is proven to be highly effective at relieving hay fever symptoms such as runny nose, sneezing and red, itchy, and watering eyes.
How long does Fexofenadine take to work?
Fexofenadine begins to work for most patients within an hour of taking a dose. Some patients may even experience symptom relief in less than 30 minutes.
Taking an increased dose of Fexofenadine is not advised and will not make the medication work any quicker. It is important to follow the user leaflet information guidance and advice given by your doctor or pharmacist.
