    not been found to be any more effective.

    Ask your doctor or pharmacist to show you the correct way to instill the eye

If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

    Medical conditions: This medication belongs to the family of medications

    people. Sulfite sensitivity is seen more frequently in those with asthma.

    Pregnancy: This medication has not been studied for use by pregnant
    women. It should be used during pregnancy only if the potential benefits outweigh
    the potential risks.
