Acne vulgaris is one of the most common skin disorders and Isotretinoin has widely been used as a treatment for its severe and resistant cases in recent years. Considering the controversy over the effect of systemic Isotretinoin on reducing the plasma level of folic acid and the negative effect of this reduction on health, this study was conducted to assess the influence of systemic Isotretinoin on the plasma level of folic acid during the years 2008 and 2009 in Khorramabad city. Materials and Methods: 61 patients including 38 women and 23 men with severe or moderate acne (age mean 23.6+6 y/o) who were resistant to conventional treatments were supplemented with 0.5mg/kg/day of oral Isotretinoin for 30 days. They were instructed not to use any other drugs with an effect on folic acid level or change their diet. The serum levels of folic acid were measured at the baseline and at the end of the treatment period. The statistical analyses were carried out using the paired T-test. Results: The mean levels of folic acid were 26.75+9.42 nmol/lit and 23.6+8.42 nmol/lit at the baseline and after 30 days of Isotretinoin supplementation respectively. This showed a significant decrease in plasma folic acid level (p=0.008). Conclusion: This study revealed a significant reduction in plasma level of folic acid following a 30 day use of oral Isotretinoin in acne patients. Concerning the important role of folic acid in metabolic functions, we recommend further studies to assess the effect of longer periods of Isotretinoin treatment as well as other relevant factors on folic acid metabolism. Moreover, folic acid supplementation and simultaneous use of Isotretinoin is recommended in patients with acne.
