Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated September 2026
Used by an eye doctor as a diagnostic aid to examine the inside of the eye (fundus/retina) by dilating the pupil (mydriasis) during eye examination.
This is an ophthalmic mydriatic used to temporarily widen (dilate) the pupil. By relaxing the iris sphincter muscle, it allows better visualization of the retina and other internal eye structures during examination.
For ophthalmic use only. Instilled into the eye(s) by a healthcare professional as advised prior to eye examination. Do not touch the dropper tip to any surface; remove contact lenses before use and reinsert only when advised. Vision may be blurred and light sensitivity may occur after use.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take the missed dose of 4 Quin Pfs 0.5 ml Solution as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.
