Effects on blood pressure of low dose oestrogen and progestagen only oral contraceptives.
Oral contraceptives containing at least 50 micrograms oestrogen and 1-4 mg progestagen can raise blood pressure [1,2]. However, there is controversy about the effect of lower doses of oestrogen [3-5] on blood pressure and especially the role of the progestagen component [6-9]. We describe the results of a prospective, controlled study of the effects on blood pressure of contraceptive preparations containing different types and dosages of oestrogen and of progestagen.
