Brief Summary
The purpose of the study is to assess the effect of folic acid administration on the blood level and the breakdown products of OC study drug (250 mcg norgestimate\[NGM\]/35 mcg Ethinyl Estradiol \[EE\]) tablets. The effect of study drug tablet intake on the blood level of folic acid is also determined.

Outcome Measures
Primary Outcomes (1)
Evaluate the pharmacokinetic drug interaction between folic acid and the study drug (250 mcg NGM and 35 mcg EE) as measured by the pharmacokinetics of the active breakdown product of NGM, norelgestromin (NGMN), and EE.
Secondary Outcomes (1)
Measure the pharmacokinetics of the active metabolite of NGM, norgestrel (NG). Evaluate the effect of the study drug on the pharmacokinetics of folic acid. Assess the safety.
