Proud to give you zero
0% brain interference due to drowsiness, that is.
What do you mean 0%?
Let’s be clear: zero is not nothing— it’s everything when it comes to antihistamines. The one with 0% brain interference that's non-drowsy? That’s the one you need to take seriously.1
Picture this: zero brain fog means staying on point during that big meeting, keeping your plans intact, and no more dozing off halfway through the day, all while tackling allergy symptoms.
Sounds like a dream come true for anyone battling allergies, right?
What if we cut brain interference to 0%?
Most antihistamines cross a protective layer of the brain called the blood-brain barrier, making you drowsy. Telfast® is different—watch as it provides fast allergy relief without crossing that barrier, keeping your mind clear and alert. Why choose between relief and alertness? Enjoy both!1,2

The science behind non-drowsy relief since 1996
Telfast®’s story began with a commitment to create allergy relief that is not only effective but also with less side effects like drowsiness.
When developing Telfast®, scientists focused on solving a major drawback of other antihistamines: drowsiness. Traditional allergy medications often cross the blood-brain barrier, triggering drowsiness and affecting alertness. The Allegra® team tackled this challenge by designing a unique oral antihistamine that avoids crossing this barrier, delivering fast-acting*, non-drowsy relief.1-5
