Mechanism of action
Ortho-Novum 1/35 belongs to a combined hormonal birth control drug with anti-aldosterone and anti-androgenic effects. The contraceptive effect is based on the interaction of various factors. The most significant effect is to provide a suppression of ovulation and changes in the properties of cervical secretions, as a result of which it becomes less penetrable for spermatozoa.

The metabolism of steroid hormones can be increased if taken together with barbiturates, some antiepileptic drugs (carbamazepine, phenytoin). A decrease in the effective concentration is manifested in the case of the simultaneous use with some antibiotics (ampicillin, rifampicin), which is associated with a change in the microflora in the intestine. The effectiveness of this contraceptive drug is reduced in the case of the regular excessive use of ethanol. When taking progestin-estrogen drugs, correction of the dosage regimen of hypoglycemic drugs may be required.
What if I miss a dose?
If the patient misses taking the pills in the first 12 hours, the risk of getting pregnant is small. Additional contraception is not required. If the missing of the pill occurred within 36 hours or more, the contraceptive effect is significantly reduced. Additional contraceptive methods are required to prevent unwanted pregnancies.
