Fexofenadine 120mg Tablets
What is Fexofenadine?
Fexofenadine, or fexofenadine hydrochloride, is a non drowsy anti histamine used to treat hay fever, other allergies, and certain types of rashes. It is generally a very well tolerated medicine. As it is a strong non drowsy anti histamine, it tends to make people less sleepy than other types of antihistamines. Alternative non drowsy and more conventional antihistamines include cetirizine, desloratadine, loratadine, and levocetirizine.
How Do Fexofenadine 120mg Tablets Work?
Fexofenadine is an antihistamine, which means it targets and blocks a receptor known as the histamine (H1) receptor. Usually, H1 receptors are involved in allergic reactions and, when activated, cause inflammation and release of a chemical called histamine. This inflammation can lead to local swelling, redness, and itching.
By blocking the H1 receptors, fexofenadine prevents this inflammatory reaction from happening, and helps to reduce the associated symptoms such as itchy skin, itchy eyes, nose irritation, skin redness, and swelling.
Unlike some other antihistamines, fexofenadine can't easily cross the blood barrier to the brain, meaning it doesn't have the same sedating effects as other similar medications.
Uses of Fexofenadine Hydrochloride
Treating Seasonal Allergic Rhinitis
Seasonal allergic rhinitis is better known as hay fever. This condition happens when pollen irritates the nose and eyes, leading to an allergic reaction. Common symptoms include:
Sneezing and an itchy nose.
A runny nose.
Itchy, watery, and/or red eyes.
Seasonal allergic rhinitis tends to be worse in the spring and summer when the pollen count is higher. It's helpful to avoid going outside when the pollen count is high, and wearing sunglasses to prevent pollen getting into your eyes and triggering symptoms.
Antihistamines like fexofenadine hydrochloride are the main medical treatment for hay fever, but steroid nasal sprays are also used. The dose of fexofenadine depends on age, but 120mg once a day is the standard dose for adults.
Managing Other Allergic Reactions
Whilst fexofenadine tablets are most commonly used to treat hay fever, it can be used to treat other types of allergies such as:
Insect bite reactions.
Skin conditions like eczema and hives.
Certain food allergies.
For a more serious allergic reaction, including situations where breathing is affected, it's important to seek medical help immediately. Very rarely, fexofenadine can cause an allergic reaction. In these cases, stop taking fexofenadine tablets and contact a doctor immediately for advice. If it's an emergency, call 999.
Dosage and Administration
Recommended Dose
For hay fever, the standard adult dose is one fexofenadine hydrochloride 120 mg film coated tablet once a day. In children aged 6-11 years, this may be reduced to 30mg twice a day.
For adults and children older than 12 years suffering from hives, the dose is increased to 180mg once a day. It may not be suitable for children younger than 12 years to take fexofenadine hydrochloride at this dose, so it's important to discuss this with a healthcare professional.
Alternative dose strengths may be taken for other causes, but this should also be discussed with a medical professional. Fexofenadine hydrochloride 120mg, 30mg, and 180mg tablets are all available to make it easier to take the right dose.
Take fexofenadine hydrochloride at its usual dose of 120 mg or 180 mg before a meal if possible, with a glass of water. Tablets should be swallowed whole and not chewed. You should not take fexofenadine hydrochloride tablets more often than recommended, as this can lead to side effects.
What to Do If You Miss a Dose?
If you take fexofenadine hydrochloride 120 mg every day and you forget a dose, take the tablet as soon as you remember. If it's close to the time you would take your next dose, then you should skip it. Don't take two tablets close together as this can lead to serious side effects.
If a child is taking fexofenadine tablets twice a day and you forget a dose, you can give it to them if it's within 4 hours of their original dose. If it's been longer than 4 hours, you should wait until the next dose.
Potential Side Effects of Fexofenadine 120mg
Serious Side Effects
Some of the more serious side effects associated with fexofenadine tablets are a fast or irregular heartbeat, severe dizziness, and difficulty breathing. In these cases, you should seek medical assistance from 111 or 999 in an emergency.
Common Side Effects
Fexofenadine tablets are generally a well tolerated medicine, but some people do experience mild side effects. Headache, drowsiness, feeling sick, and dizziness are the most common side effects. Although fexofenadine is a non drowsy antihistamine, many people do still feel sleepy after taking the medication.
If you're taking fexofenadine tablets every day and the side effects are bothering you, speak to your doctor or pharmacist.

Precautions When Taking Fexofenadine
Most people are able to take fexofenadine tablets safely. However, anyone with a history of allergic reaction to fexofenadine hydrochloride, or other substances listed in the medicines patient information leaflet, should avoid taking fexofenadine tablets.
Patients with heart disease should talk to a doctor or pharmacist before taking the medication, as fexofenadine may worsen the risk of heart palpitations and/or an increased heart rate. People with a history of epilepsy, liver disease, or kidney problems should also discuss their medical history with a healthcare professional before starting the medication.

How many days does it take for fexofenadine to work?+−
Fexofenadine doesn't need to be taken every day to be effective. It should start to work after 30 minutes and can be effective when taken as a one-off dose. However, if symptoms continue, you will need to continue to take fexofenadine daily to experience the positive effects.
