Hello. i am currently taking 100 mg of lamotrigine daily. recently i have been having cloudy vision. is it probable that it is being caused by the medication? if so, what is my next step?

See your physician who prescribed the medication and tell him of your symptoms. He will decide what you should do. Good Luck

Chronic use of lamotrigine would not cause recent onset of cloudy vision. Instead, urge visit to ophthalmologist to check for refractive visual changes, and other eye disorders. Do notify prescribing doctor, but at your relatively modest dose, would not find compelling reason to change at this point.
