Antihistamine and Decongestant (eye preparation)
Last reviewed May 2026
Who is this for?
This is a combination eye drop that contains two active ingredients — antazoline (an antihistamine that stops allergic reactions in the eye) and tetryzoline (a decongestant that shrinks swollen blood vessels to reduce redness). Together, they quickly relieve itchy, red, watery eyes caused by allergies.
