Hi. I've been on lamictal for over 2 yrs (400mg/day) and yes, the blurry vision I swear is a side effect. Mine can be clear as can be and 30 minutes later really blurry and it may last for 15 minutes or for hours or all day. At some point it gets clear again then blurs. Different degrees of blur too. Prescription glasses out of the equation as vision is so off. Hopefully the med is doing well for you otherwise. Have no probs at all with periods. Have noticed many "weird" things taking this med but I consider minor and stay with med as it woeks great for me.
hour and a half 3 years morning dose prescription glasses blurry vision lamictal weird things probs blur 15 minutes 30 minutes periods
