What is Alamast used for? Alamast is used to prevent itching of the eye caused by allergies. Alamast should not be used to treat contact lens-related problems. You may notice decreased itching within a few days, but frequently longer treatment (up to four weeks) is necessary.

General Precautions with Alamast?

  • Do not wear contact lenses if your eyes are red.
  • If you wear soft contact lenses and your eyes are not red, remove the lenses before using Alamast. Wait at least 10 minutes after using Alamast before putting in your contact lenses, because Alamast contains a preservative that may be absorbed by the lens.
  • Do not allow the tip of the dropper to touch the eyelids or surrounding areas, because this may contaminate the medicine.
  • Wait at least 10 minutes after using Alamast before putting in your contact lenses.
  • Keep the bottle tightly closed when not in use.

What should I tell my doctor or health care provider?
