Instruction to patients - illustrations


  1. Avoid placing Crolom (cromolyn ophthalmic) ® solution directly on the cornea (the area just over the pupil), because it is especially sensitive. You will find the administration of eye drops more comfortable if you place the drops just inside the lower eyelid as shown in Figure 5 on the previous page.
  2. To avoid contamination of the solution, do not touch dropper tip to the eye, fingers or any other surface. Replace cap after use. It is recommended that any remaining contents be discarded after the treatment period prescribed by your physician.
  3. Store between 15°-30°C (59°-86°F). Protect from light – store in original carton. Keep tightly closed. Replace cap immediately after use.
  4. Keep out of the reach of children.
  5. Do not use with any other ocular medication unless directed by your physician. Do not wear contact lenses during treatment with Crolom (cromolyn ophthalmic) ®.
