Same number of epilepsy patients with no history of taking antiepileptic medicine were taken as control. The mean level of vitamin B&lt;sub&gt;12&lt;/sub&gt; in carbamazepine-treated epileptic patients was 265.5 pg/mL whereas it was 478.3 pg/mL in control. Increased duration of treatment of carbamazepine in epilepsy caused significantly decreased level of serum vitamin B&lt;sub&gt;12 &lt;/sub&gt;(Pearson correlation coefficient, r = -0.9, p&amp;lt;0.0001). In conclusion, serum vitamin B&lt;sub&gt;12&lt;/sub&gt; level significantly decreased in relation to duration of carbamazepine treatment in epileptic patients.&lt;/p&gt;}, number={4}, journal={Bangabandhu Sheikh Mujib Medical University Journal}, author={Islam, Mohammad Tariqul and Sobhan, Khair M. and Shawly, Mahjabin Rahman and Saleheen, Shafiqur and Emran, Mohammad Masum and Hannan, M.
