Fexofenadine is used for common allergies, such as hay fever and pet allergies.

How long does fexofenadine stay in your system?

How much fexofenadine can I take?

You should only take 1 180 mg fexofenadine tablet per day. If this isn’t enough to relieve your hay fever symptoms after taking it for several weeks, speak to your doctor. You may need to try a different medication or be referred to an immunologist.

How long does fexofenadine take to work?

Fexofenadine should start to work within 1 hour. The best effect can be seen by taking the medication every day throughout hay fever season.

What can you not take with fexofenadine?

You can’t take indigestion remedies containing aluminium or magnesium within 2 hours of taking fexofenadine, as it could affect how well it works. You should also speak to your doctor if you take apalutamide or any other antihistamines.

Should I take fexofenadine at night or morning?

You can take fexofenadine at any time of day, although you should stick to the same time each day. Find a time that works for you.

If this isn’t enough to manage your hay fever symptoms, speak to a doctor about getting fexofenadine 180 mg tablets instead, or get a prescription and your treatment online from ASDA Online Doctor.

Why can't you drink orange juice with fexofenadine?

Orange, apple, and grapefruit juice shouldn’t be consumed with fexofenadine. They’ve been known to interact with the medication and increase the risk of side effects.
