Side Effects

The most common side effects of emedastine difumarate include headache, burning or stinging in the eyes, and blurred vision. Less common side effects can include dry eyes, eye pain, and sensitivity to light.

Interactions

Emedastine difumarate is not known to interact significantly with other drugs. However, it is always recommended to inform your healthcare provider about all the medications you are currently taking, including over-the-counter drugs and dietary supplements.

Precautions

Emedastine difumarate should not be used by individuals who are allergic to it or any of its ingredients. It should be used with caution in individuals with narrow-angle glaucoma, and in those who wear contact lenses, as it may cause discoloration.

Pregnancy and Lactation
