How to use fexofenadine
If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed, usually 2 times daily (every 12 hours).
If you are using the liquid form of this medication, shake the bottle well before each dose and measure the dose carefully using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Take the tablet/capsule or liquid form of this medication with or without food. If you are using the rapidly-dissolving tablet, take it on an empty stomach. Allow the rapidly-dissolving tablet to dissolve on the tongue and then swallow, with or without water. Do not remove the tablet from the blister pack until right before using.
If you need a liquid to take this medication (such as when taking the tablets/capsules), then take this medication with water. Do not take with fruit juices (such as apple, grapefruit, or orange) since they may decrease the absorption of this drug.
The dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this medication more often than directed. For adults, take 120-180 mg by mouth once daily. For children using the oral suspension or the tablet form, give 30 mg by mouth twice daily if ages 6-11, if 12 years old and above, give 120- 180 mg by mouth once daily.
Do not take antacids containing aluminum and magnesium within 2 hours of taking this medication. These antacids can decrease the absorption of fexofenadine.
Do not drink fruit juice at the same time that you take fexofenadine. Certain fruit juices (eg, grapefruit, apple, orange) may decrease fexofenadine’s effectiveness.
Tell your doctor if your condition does not improve or if it worsens.
