Important Safety Information

Before starting CYSTADROPS, tell your healthcare provider (HCP) about all your medical conditions, including if you are pregnant or plan to become pregnant, breastfeeding or plan to breastfeed. Tell your HCP about all the medicines you take, including any prescription and over-the-counter medicines, vitamins, or herbal supplements.

To minimize the risk of contamination, do not touch the dropper tip to the eyelids, surrounding areas, or to any surface. Keep bottle tightly closed when not in use.

What are the possible side effects of CYSTADROPS?
CYSTADROPS may cause side effects including:

• A condition where the pressure inside the skull increases for unknown reasons has been reported with cysteamine taken by mouth or cysteamine eye drops (used at the same time as cysteamine taken by mouth). This condition went away with the addition of medicine that increases the production of urine.
• Use with soft contact lenses should be avoided as CYSTADROPS contains the preservative benzalkonium chloride which may be absorbed by soft contact lenses. Remove contact lenses prior to application. Lenses may be reinserted 15 minutes following administration.
