Boxed warning

CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS.

Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs, including Blisovi Fe 1/20, are contraindicated in women who are over 35 years of age and smoke (see CONTRAINDICATIONS and WARNINGS). BRIEF SUMMARY PATIENT PACKAGE INSERT Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives are strongly advised not to smoke. Oral contraceptives, also known as "birth control pills" or "the pill," are taken to prevent pregnancy and, when taken correctly, have a failure rate of about 1% per year when used without missing any pills. The typical failure rate of large numbers of pill users is less than 3% per year when women who miss pills are included. For most women, oral contraceptives are also free of serious or unpleasant side effects. However, forgetting to take pills considerably increases the chances of pregnancy. For the majority of women, oral contraceptives can be taken safely. […]

What is ethinyl estradiol and norethindrone used for?

From the label: indications and usage

Blisovi Fe 1/20 is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptives are highly effective. Table I 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, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. […]

Is there a generic for ethinyl estradiol and norethindrone (Nortrel)?

The FDA approved the first generic ethinyl estradiol and norethindrone on January 29, 1987. 118 generic applications are approved; 70 of them carry a current (not discontinued) marketing status in Drugs@FDA; that status is not evidence that the generic is on sale. Drugs@FDA also holds 1 tentative approval: the FDA found the generic approvable, but patents or exclusivity keep it from final approval for now.

FDA's NDC Directory lists ethinyl estradiol and norethindrone from 18 labelers under a generic (ANDA) application and from 1 brand labeler. A listing means the company has registered the product for sale; it does not show that every pharmacy stocks it.

The Orange Book lists 1 patent for Lo Loestrin Fe tablets, the last expiring on February 2, 2029; a patent listed only for Femlyv tablets runs to June 24, 2041. A patent or exclusivity date is not the date a generic goes on sale: court cases and settlements move it either way.
