Question: black out feeling, cravings, fatigue, cold extremities

 lightguide - Mon Oct 26, 2009 3:51 pm

I feel like I'm going to black out sometimes. I crave carbs (not the complex ones), I have fatigue, and cold extremities. None of this was a problem until I started a new med lamotrigine.

User avatar Hi,
I sincerely hope you are using this medication (lamotrigine) under medical supervision.

This drug, a 'sodium channel blocker' is approved by FDA only for a handful of indications(such as partial seizures,seizures in 'Lennox-Gastaut syndrome', a very severe form of epilepsy & in Bipolar I disorder).

All fainting episodes may not be the "drop attacks" associated with 'Lennox-Gastaut syndrome'.

In this condition (as far as my knowledge goes), the person falls NOT due to 'black outs', but due to the spasms and disturbances in balance.

There are reports in the literature of studies on the use of this drug in cocaine abuse.

Also there are reports of abuse of this drug, perhaps due to the mistaken belief that this works better in epilepsy in general.

It is believed that women are more prone to side effects of this drug.

I must caution the public that this drug has very severe side effects and should not be used without strict medical supervision.

Best wishes!
