title: Serum level and 24hr. excretion pattern of potassium following the intake of combined oral contraceptives.
abstract: Serum level and 24hr urinary excretion pattern of potassium have been studied in 104 healthy women, aged 18-44 years, using combined oral contraceptives for a period of 3-48 months, and results have been compared with those obtained from 21 healthy controls of the same clinic, aged 19-40 years, using IUD. There was no significant change observed in serum potassium level, but 24hr urinary excretion pattern of potassium decreased significantly in 90% of the individuals equivalent to 2.6-78.3% of the mean control, possibly due to a retention of potassium in the cells.
