Ethynodiol: Side Effects, Uses & Monitoring

Labeled uses

Zovia 1/35E and Zovia 1/50E are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptive products such as Zovia 1/50E, which contain 50 mcg of estrogen, should not be used unless medically indicated. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization and progestogen implants and injections, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. Table 1.
