HOW DOES CYSTADROPS WORK?

CYSTADROPS (sys-tah-drops) is a prescription eye drop that reduces cystine crystals in the cornea with practical, 4 times a day dosing.

  • CYSTADROPS is a viscous solution that coats the entire surface of the cornea.
  • CYSTADROPS penetrates throughout the cornea to reach all layers of the cornea when used as directed.
  • The active ingredient of CYSTADROPS, cysteamine, enters the lysosomes and breaks apart cystine into smaller pieces that can then exit the lysosomes.

HOW EFFECTIVE IS CYSTADROPS?

CYSTADROPS reduced cystine crystals in all layers of the cornea.

CYSTADROPS was approved by the Food and Drug Administration based on studies that demonstrated safety and effectiveness in people with cystinosis.

One study showed a 12% decrease in cystine crystals in the cornea after 30 days of treatment and a 40% decrease in cystine crystals in the cornea after 90 days.

CYSTADROPS penetrated throughout the layers of the cornea and dissolved cystine crystals in every layer.

The cystine crystal reduction was maintained over time when CYSTADROPS was used daily, as directed.

WHAT ARE POSSIBLE SIDE EFFECTS OF CYSTADROPS?

The most common side effects are eye pain (stinging), blurred vision, eye irritation (burning), eye redness, discomfort at instillation site (sticky eyes or sticky eyelids), eye itching, watery eyes, medicine deposit on the eye lashes or around the eyes.

Talk to your doctor if you are experiencing any side effects due to treatment.
