title: An observational study of trigeminal neuralgia patients taking carbamazepine during the fasting month of Ramadan.
abstract: Trigeminal neuralgia is an agonising orofacial pain affecting unilaterally the distribution of the trigeminal nerve and it usually occurs in the middle and older age groups. Carbamazepine which is an anti-neuralgic as well as an anti-convulsant medication is the first line drug for treatment of trigeminal neuralgia. It is commonly taken as one tablet (200 mg) three times a day.
  
  
  
  This is an observational study carried out from April to September 2014 to determine how Muslim patients on carbamazepine treatment for trigeminal neuralgia cope with their neuralgic pain. The pattern of how the medication was taken during the fasting month of Ramadan was also observed.
  
  
  
  A total of 29 patients participated in this study and 27(93%) observed the fast. Ten of them adjusted the carbamazepine dose from three times pre-Ramadan to twice daily during the fasting month. Three patients continued fasting despite feeling the pain during the daytime while five patients had their pain under control with the newly adjusted dose.
  
  
  
  Medical professionals should advise trigeminal neuralgia patients on how to take and adjust their carbamazepine dose during the fasting month.
