== Sleep disturb % is misstated. ==
==Side effects==
According to Bertram G. Katzung's 7th Edition of basic and clinical pharmacology on page 396, Lamotrigine's symptoms can include dizziness, somnolence, headache, diplopia, nausea, and rash. Sometimes the rash can be a mild and itchy adverse reaction in the skin (personal experience), since it has been said to bind to melanin there and in the eyes (I don't remember where I heard this, but it was a legitimate source). Lamotrigine has a serious risk in its potential for steven's johnson's syndrome, which begins manifestation as a rash. This is why it is essential that lamotrigine treatment begin slowly--the book mentioned above states that patients taking valproate must begin treatment at no more than 25mg every other day. Steven's Johnson's syndrome is rare, and it is almost unheard of after a patient has finished transitioning onto the medication.

As with any medication, it's a strain on the body, common sense indicates that users need more water while taking this medication. I think it made me sweat more as well, which might be attributable to its moderately high level of protein binding (the book says 55%). I am not an M.D., but an economics student and informed patient. good luck!

It's only 6.4%.
==Legal status in Japan==
I'm not sure if I'm putting this in the correct section. However, here goes: as a user of Lamictal and frequent visitor to Japan I was concerned to read about lamotrigine's classification as a narcotic in Japan. Japan has some worryingly bureaucratic processes around the importation of medicines. After conversation with the local Japanese consulate, and some detailed web searching, I faxed some questions about lamotrigine to the relevant department in Japan. This is the reply I got: <br>
Dear Mr. [name removed]<br>
 
I got fax from you.<br>
 
Lamictal is NOT a narcotic drug (it is a prescription drug) in Japan, so you do not need to fill in an application form to import a narcotic.<br>
Under the Japanese regulation of importing drugs, people can import one month supply of prescription drugs without any procedures. If the quantity of Lamictal you intend to bring into Japan is less than one month supply, you do not need to fill in any forms. A prescription from your doctor would make customs clearance smooth.<br>
If you intend to bring more than one month supply, you need to fill in “Import Report for Medication” form and apply for the Yakkan Shoumei, a kind of import certification. You have to apply for the Yakkan Shoumei” every time you visit Japan if you bring more than one month supply each time.<br>
 
Regarding the Yakkan Shoumei, please check our website below:<br>

The book Bad Pharma notes that 63% of the trials of this drug have not been published. When dealing with medications, should we consult www.alltrials.net ? People do rely on the information provided by Wiki and if we are passing on bad data, people may be harmed. I know that this would be a huge amount of work but I am prepared to cover as many as possible. I've added patents & papers to over 800 pages (from several IP addresses, but you can spot my standard 'added patent' format.
If Wiki supports alltrials, we will be providing information for both doctors and patients. To do this properly we need to get alltrials and specifically Dr. Ben Goldacre to find a feedback mechanism. In addition, checking references with retraction watch will ensure that we give only the best, unbiased references to users. I feel strongly about this because Lamotragine almost killed me because of an unreported side-effect. Maybe the side-effect WOULD be known if the trials were ALL published. <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/81.99.74.135|81.99.74.135]] ([[User talk:81.99.74.135#top|talk]]) 22:28, 1 January 2017 (UTC)</small> <!--Autosigned by SineBot-->
:Patents are not reliable sources in WP, so you have added a bunch of bad referencing that is probably [[WP:OR]] to boot - you need some secondary source that says patent X is relevant to drug Y. See [[WP:SPS]] which specifically mentions patents. I hope you will undo all those edits.

Receptor activity listed in article not found in cited source

[edit]

Receptor activity is listed as antagonistic at 5-HT3 and σ receptors with IC50 of 18 μM and 145 μM, respectively. The inline citation is [5] https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=d7e3572d-56fe-4727-2bb4-013ccca22678.
