Specific Alcaftadine Precautions and Warnings

Some warnings and precautions to be aware of prior to using this medicine include the following:
 
  • If you wear contact lenses, you must remove them to use the eye drops. In order to prevent the lens from absorbing the preservative used in this medication, make sure to wait at least 10 minutes after using the drops before reinserting the lens. Do not wear your contact lenses if your eye is still red.
     
  • To prevent contamination of the drops, do not touch the tip of the dropper to any surface, including the surface of the eye.
     
  • Alcaftadine is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are currently unknown (see Lastacaft and Pregnancy).
     
  • It is unknown if alcaftadine passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to using the drug (see Lastacaft and Breastfeeding).
