Interactions Telfex does not undergo hepatic biotransformation and therefore does not interact with other medicinal products via hepatic mechanisms. Co-administration with erythromycin or ketoconazole increases plasma fexofenadine levels 2–3 times, but without QT interval changes or increased adverse reactions. No interaction with omeprazole was observed. However, antacids containing aluminum and magnesium hydroxide reduce bioavailability if taken within 15 minutes before Telfex, likely due to binding in the gastrointestinal tract. It is advisable to maintain a 2‑hour gap between Telfex and such antacids.
Contraindications Contraindicated in patients with known hypersensitivity to Fexofenadine Hydrochloride or any of its ingredients.
