However, this group of drugs is used to treat other diseases such as neuralgia following herpes zoster which are very effective in pain mitigation.5 Although most systemic complications of the mentioned drugs such as hepatitis and renal insufficiency are more considered, it is better to remember that most of them result in very severe mucocutaneous complications such that the drugs should be changed or their consumption should be stopped.6 Since anticonvulsants lead to a lot of dermal complications such as rash, hypersensitivity syndrome, alopecia, pseudolymphomatous lesions, gingival hyperplasia, erythema multiforme, acneiform eruptions, Vasculitis, Drug lupus, and Stevens-Johnson syndrome.7,8 Prescribing the drugs considering complete information of its kind and methods of treating the mentioned complications is recommended in order to prevent disability or even mortality.
