I've been on this med, but had that sort of thing way before being on Lamictal.
I guess it can be related, or even anemia, can cause a person to bruise easier. If a person is taking blood thinners, bruising easy occurs too. If it seems to be bothersome,and increasing, give the prescribing pdoc a call.
I take 200mg's pf Lamictal per day, haven't had anything abnormal happen, as far as side effects.
Breakout,is probably just that,mild acne, and not the "rash", I would think you would have gotten it when you started the med, plus it is an extrememly rare, as far as the Stevens Johnson rash,but check with doc. Getting back to the bruises,vitamin defeciences can cause them too.
Once I was on Lamictal I was able to stop AD's, that weren't working any longer due to "poop out", it happens with SSRI' after a couple of yrs of use, with some people.
Many of my leg bruises have been from my 65lb puppy playfully running and jumping on me,looks like I was beat up, LOL!! My weight gain (age and not exercising) is causing me to be clumsy, so I'm hitting either my legs,arms into something, so maybe something similar is happening to you, non pill related. Check it out with the doc, to be sure.
Please take care,
Roe
