Can you use pink eye medicine on a stye?

Using pink eye medicine on a stye is not recommended without consulting a healthcare professional. Pink eye (conjunctivitis) and styes are different conditions; a stye is an infection of the eyelid's oil glands, while pink eye affects the eye's surface. Over-the-counter pink eye treatments may not address the underlying cause of a stye, which usually requires warm compresses or specific treatments. Always seek advice from a doctor for the appropriate treatment.
