What is fexofenadine 180 mg used for?
Fexofenadine 180 mg is typically used to treat allergy symptoms such as sneezing, runny nose, itching, and watery eyes caused by hay fever (seasonal allergic rhinitis). It may also be used for chronic allergy symptoms, depending on the specific product and prescribing information.
How does fexofenadine 180 mg work?
Fexofenadine is an antihistamine (an H1 blocker). It reduces the effects of histamine, a chemical your body releases during allergic reactions.
How do you take fexofenadine 180 mg?
Many formulations that are labeled “180 mg” are taken once daily for allergic symptoms, but exact dosing can depend on the product (tablet vs. oral suspension), your age, and kidney function. Follow the directions on the specific label or from your clinician.
What side effects can happen with fexofenadine?
Common side effects can include headache, nausea, dizziness, and dry mouth. Seek urgent care if you have signs of a serious allergic reaction (such as swelling of the face or throat, trouble breathing, or widespread rash).
Can you take fexofenadine 180 mg with fruit juice or other foods?
Some foods and drinks can reduce how much fexofenadine your body absorbs. Checking the specific package directions is important, especially regarding citrus juices such as grapefruit or orange juice, which can affect absorption for certain antihistamines.
What should people with kidney problems know?
Because fexofenadine is cleared by the body through the kidneys, people with impaired kidney function may need dose adjustments or closer monitoring. If you have kidney disease, ask a clinician or pharmacist what dose is appropriate.
What are the major brand and availability considerations?
Fexofenadine has both brand-name and generic versions for allergy treatment. Prices and coverage can vary by product and location.
