fexofenadine official prescribing information indications warnings dosage
Fexo usually refers to fexofenadine (brand example: Allegra), a second-generation H1 antihistamine.
Used for: allergy symptoms such as sneezing, runny/itchy nose, itchy or watery eyes, and hives (urticaria).
Drowsiness: usually non-sedating, though a few people may still feel sleepy.
Common adult doses: 120 mg once daily for seasonal allergies, or 180 mg once daily for hives. Follow the exact dose on your product label or prescription.
How to take: with water. Avoid fruit juices, especially grapefruit, orange, and apple juice, around the dose because they can reduce absorption. Separate aluminum/magnesium antacids by at least 2 hours.
Check with a clinician/pharmacist first if you have kidney disease, are pregnant/breastfeeding, or are choosing a dose for a child.
fexofenadine acetaminophen drug interaction official source
Yes. Fexofenadine (Fexo) and paracetamol (acetaminophen) can generally be taken together. There is no known clinically significant interaction between them.
Take each at its normal recommended dose. Be careful not to double-dose paracetamol by also taking a cold/flu medicine that contains it.
Avoid or ask a pharmacist/doctor first if you have:
Liver disease, heavy alcohol use, or are taking other paracetamol-containing products
Kidney disease, because fexofenadine dosing may need adjustment
Severe symptoms such as breathing difficulty, facial/throat swelling, confusion, or persistent high fever
For adults, do not exceed the paracetamol amount stated on your product label or prescribed by your clinician.
