Hi I have been having a strong metallic taste in my mouth now for a few days and on one day about 2 weeks ago. And i found only one rash spot so far since it's sunday evening here i cannot call my GP yet. And i am unsure if i would have to.

So i will ask here, is a terrible persistent metal taste a side effect of lamotrigine? It could also have been from methformine. But i haven't had side effects of it for over 18 months if not longer. This rash is also nothing to be concerned about right?
