It blocks histamine H1 receptors in the peripheral tissues that drive allergy symptoms — sneezing, runny nose, itchy eyes, skin hives — without crossing the blood-brain barrier meaningfully, so it does not make most people drowsy. Onset: 60 minutes; duration: 12–24 hours. Once-daily dosing. The most non-sedating antihistamine available<\/strong> — preferred for drivers, pilots, and anyone who cannot afford any drowsiness. Do not take with fruit juice<\/strong> (grapefruit, orange, apple) — juice reduces absorption by ~30–40% via OATP inhibition. Safe for long-term daily use (months to years) in most adults. Common side effects: mild headache, dry mouth, fatigue. Avoid in known hypersensitivity; dose-reduce in significant renal impairment.<\/p>\n<\/div>\n \ud83d\udce6 Ka\u017ed\u00e1 objedn\u00e1vka je pokryta na\u0161\u00ed Z\u00e1rukou op\u011btovn\u00e9ho odesl\u00e1n\u00ed<\/strong><\/a> \u2014 pokud va\u0161e z\u00e1silka nedoraz\u00ed do 20 pracovn\u00edch dn\u016f, p\u0159epos\u00edl\u00e1me ji.<\/p>\n Na\u0161e generick\u00e9 l\u00e9ky poch\u00e1zej\u00ed od v\u00fdrobc\u016f certifikovan\u00fdch WHO-GMP a jsou expedov\u00e1ny po cel\u00e9m sv\u011bt\u011b v diskr\u00e9tn\u00edm, nen\u00e1padn\u00e9m balen\u00ed \u2013 na vn\u011bj\u0161\u00ed stran\u011b bal\u00edku nen\u00ed uveden n\u00e1zev l\u00e9ku.

Bioequivalence to the originator brand (Allegra \/ Telfast (Sanofi, 1996)) is required by regulatory authorities, so clinical effect is the same at the same dose.<\/p>\n Grapefruit, orange, and apple juice contain compounds (flavonoids) that inhibit intestinal OATP (organic anion transporting polypeptide) — the transporter fexofenadine uses to cross into the bloodstream. Taking fexofenadine with fruit juice can reduce plasma levels by 30–40%, weakening its effect. Take with water and separate any fruit juice by at least 4 hours.<\/p>\n Essentially no sedation<\/strong> — fexofenadine has the lowest brain penetration of any 2nd-generation antihistamine and is specifically approved by aviation authorities for use by pilots in many jurisdictions.
