Look up the side effects on Lamictal on www.drugs.com Researchers on a new med write down every conceivable side effect from the med they are testing on people, before it becomes an approved drug. That is why the side effects lists on this website are so long. If your condition is not listed, then IMO it is very unlikely that it is Lamotragine causing you problem. Here is the link for this med. Your side effect does not appear to be listed.

This website also lists the side effects by medical specialty for medical professionals. For example, nervous system, ocular, and gastrointensital. Then it lists all of the references were used to compile this information. Here is the entry for psychological side effects of Lamotragine followed by the entry for cardiovascular side effects. You may need a medical dictionary to help you understand some of the terms used. I have included a link to one at the bottom. I have listed cardiovascular since it is the only specialty involving the vascular system, but it may not apply to you.
