What is Fexofenadine?

Fexofenadine is an antihistamine tablet used to relieve the symptoms of hay fever (seasonal allergic rhinitis) such as sneezing, a runny or blocked nose, red or watery eyes, and itchy eyes or nose. 

It contains the active ingredient fexofenadine hydrochloride. It is considered a non-sedating antihistamine, which means it is less likely than other antihistamines to cause drowsiness as a side effect.

It is available in two strengths: fexofenadine 120mg and fexofenadine 180mg. Our doctors can only prescribe the 120 mg strength online. You can also request Telfast online, which is the branded version.

How does it work?

Hay fever symptoms are caused by an allergic reaction to pollen. When you come into contact with pollen, the body can react by releasing too much of a chemical called histamine. When too much histamine is released, it can cause hay fever symptoms like itching, sneezing, and watery eyes.

Fexofenadine is an antihistamine medicine. This means it works to block the effect of histamine in the body. This helps to reduce the reaction of the body to pollen. By doing so, it helps to improve hay fever symptoms.

How long does it take to work?

When taking it for hay fever symptoms you should take it every day during the hay fever season.

Some people find it better to start taking it just before the hay fever season starts to help prevent symptoms. If you stop taking it when the pollen count is still high, you may notice your hay fever symptoms return.

It starts to work around one hour after taking a dose. One dose is enough to be effective for 24 hours. 

Alternative treatments

If you find the antihistamine fexofenadine isn’t effective for you, there are several other treatments you can try. Other non-sedating antihistamines that you can buy over the counter include loratadine, cetirizine, and Benadryl Allergy Relief (contains acrivastine). Desloratadine and levocetirizine are non-sedating antihistamines that are only available on prescription.

Some antihistamine medications are known as drowsy antihistamines because they are more likely to cause drowsiness as a side effect. This includes Piriton, which contains the active ingredient chlorphenamine.


There are also specific treatments for different hay fever symptoms. Eye drops, such as Optilast and Optrex, can be useful for symptoms like itchy, watery or red eyes. Nasal symptoms can be relieved by using nasal sprays like Beconase, Avamys and Dymista.

Can I take two fexofenadine 180mg?
You should take this medicine exactly as your doctor has told you to. The recommended dose for hay fever is one tablet once a day. In some circumstances, your doctor may prescribe higher doses for you but this significantly increases the risk of side effects.

Directions

How to take Fexofenadine

For adults and children aged 12 and over, the recommended dose is one tablet daily. Take your dose with water before a meal. Always take this medicine exactly as your doctor has told you to. 

It’s unlikely to make you feel drowsy. However, if the tablets do make you feel drowsy you should not drive or operate machinery.

Warnings

Cautions

This medicine isn’t recommended for people over the age of 65. This is because there hasn’t been enough research on its effect in this age group. 

Avoid taking indigestion remedies containing aluminium and magnesium at the same time as fexofenadine. These can reduce the amount of fexofenadine that the body absorbs. You should leave a space of at least 2 hours between taking fexofenadine and indigestion remedies. 

There can be drug interactions between fexofenadine and other medicines that can make you drowsy. You may find that taking these together increases the side effect of drowsiness.

If you are pregnant, you should speak to your doctor for medical advice before taking fexofenadine as it may be unsuitable. It should not be used by breastfeeding women.

Drinking alcohol with fexofenadine may increase the likelihood of feeling drowsy or sleepy.
