CITIZEN DOSSIER

Careprost interactions are usually local rather than systemic because bimatoprost exposure in blood is low. The most important interaction is with other prostaglandin-analog eye drops, since using them together can reduce the pressure-lowering effect or make the response less predictable. Caution also matters with other glaucoma drops because the total eye-pressure effect should be monitored, especially if several agents are used at once. If contact lenses are worn, they should not be in the eye during application because preservatives can be absorbed by the lens and increase irritation. Eye irritation, redness, darkening of eyelid skin, or stronger lash changes may be more noticeable if other eye products are used too close together. Separate different eye drops by several minutes and avoid self-combining multiple lash or glaucoma products without medical guidance.
