Evaluation of emotional reactions to oral contraceptive use

Abstract

A review of available clinical studies indicates that 10 to 40 per cent of oral contraceptive users may suffer mild to moderate depression syndromes. Clinical and animal data indicate that a variety of mechanisms may be involved, including alterations in folate, pyridoxine, and vitamine B12 metabolism, as well as related effects on biogenic amine metabolism. Interactive effects may result, such as impairment of usual coping mechnisms and psychological defenses by altered central nervous system function.

PIP: Literature on the association of oral contraceptives (OCs) with psychological disturbances is reviewed. The data from available clinical studies indicate that perhaps 10-40% of OC users may experience mild to moderate depression syndromes characterized by tiredness, lethargy, sadness and, in some cases, loss of libido. These psychological alterations may involve numerous mechanisms including changes in folate, pyridoxine, and Vitamin-B12 metabolism, and related effects on biogenic amine metabolism. The interaction of these impaired mechanisms may disturb usual coping functions and psychological defenses by altered central nervous system activity.
