Naphcon-A - can it be used with contacts in your eyes?

I realize this answer is very, very late but may help someone in future.

No, you can't use Napchon-A with contacts ... the lenses need to be removed before using the eyedrops.

How to use Naphcon-A:

Use Naphcon-A as directed by your doctor. Check the label on the medicine for exact dosing instructions.

If Naphcon-A contains particles or is discolored, do not use it.

Remove contact lenses before using Naphcon-A.

To use Naphcon-A, first, wash your hands. Tilt your head back. Using your index finger, pull the lower eyelid away from the eye to form a pouch. Drop the medicine into the pouch and gently close your eyes. Immediately use your finger to apply pressure to the inside corner of the eye for 1 to 2 minutes. Do not blink. Remove excess medicine around your eye with a clean tissue, being careful not to touch your eye. Wash your hands to remove any medicine that may be on them. To prevent germs from contaminating your medicine, do not touch the applicator tip to any surface, including your eye. Keep the container tightly closed.

You may feel a brief tingling sensation in your eye and your pupils may become temporarily enlarged when using Naphcon-A.

If you miss a dose of Naphcon-A and you are using it regularly, use it as soon as possible. If several hours have passed or if it is nearing time for the next dose, do not double the dose to catch up, unless advised by your health care provider. Do not use 2 doses at once.
