Effects of Other Drugs on Oral Contraceptives 78 Rifampin: Metabolism of both norethindrone and ethinyl estradiol is increased by rifampin. A reduction in contraceptive effectiveness and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. Antibiotics: Pregnancy while taking oral contraceptives has been reported when the oral contraceptives were administered with antimicrobials such as ampicillin, tetracycline, and griseofulvin.
However, clinical pharmacokinetic studies have not demonstrated any consistent effect of antibiotics other than rifampin on plasma concentrations of synthetic steroids. Other: Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol concentrations, possibly by inhibition of conjugation. A reduction in contraceptive effectiveness and increased incidence of breakthrough bleeding has been suggested with phenylbutazone.
Oral contraceptive combinations containing ethinyl estradiol may inhibit the metabolism of other compounds. Increased plasma concentrations of cyclosporine, prednisolone, and theophylline have been reported with concomitant administration of oral contraceptives. In addition, oral contraceptives may induce the conjugation of other compounds.
Decreased plasma concentrations of acetaminophen and increased clearance of temazepam, salicylic acid, morphine, and clofibric acid have been noted when these drugs were administered with oral contraceptives.
Certain endocrine and liver function tests and blood components may be affected by oral contraceptives:. Increased thyroid binding globulin TBG leading to increased circulating total thyroid hormone, as measured by protein-bound iodine PBI , T 4 by column or by radioimmunoassay.
Free T 3 resin uptake is decreased, reflecting the elevated TBG; free T 4 concentration is unaltered. Sex-binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; however, free or biologically active levels remain unchanged. Serum folate levels may be depressed by oral contraceptive therapy.
This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives. Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers, and a few adverse effects on the child have been reported, including jaundice and breast enlargement.
In addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child.
Safety and efficacy are expected to be the same for postpubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated. See patient labeling printed below. There is evidence of an association between the following conditions and the use of oral contraceptives, although additional confirmatory studies are needed:. The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug-related:.
The following adverse reactions have been reported in users of oral contraceptives and the association has been neither confirmed nor refuted:. Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. The following non-contraceptive health benefits related to the use of oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.
The tablet dispenser has been designed to make oral contraceptive dosing as easy and as convenient as possible. The tablets are arranged in either three or four rows of seven tablets each, with the days of the week appearing on the tablet dispenser above the first row of tablets. Note: Each tablet dispenser has been preprinted with the days of the week, starting with Sunday, to facilitate a Sunday-Start regimen. If the patient is using the Day-1 Start regimen, she should place the self-adhesive day label strip that corresponds to her starting day over the preprinted days.
Important: The patient should be instructed to use an additional method of protection until after the first week of administration in the initial cycle when utilizing the Sunday-Start regimen.
Two dosage regimens are described, one of which may be more convenient or suitable than the other for an individual patient. For the initial cycle of therapy, the patient begins her tablets according to the Day-1 Start or Sunday-Start regimen. With either regimen, the patient takes one tablet daily for 21 consecutive days followed by one week of no tablets.
Sunday-Start Regimen: The patient begins taking tablets from the top row on the first Sunday after menstrual flow begins. When menstrual flow begins on Sunday, the first tablet is taken on the same day. The last tablet in the dispenser will then be taken on a Saturday, followed by no tablets for a week 7 days. For all subsequent cycles, the patient then begins a new tablet regimen on the eighth day, Sunday, after taking her last tablet. Following this regimen, of 21 days on—7 days off, the patient will start all subsequent cycles on a Sunday.
Day-1 Regimen: The first day of menstrual flow is Day 1. The patient places the self-adhesive day label strip that corresponds to her starting day over the preprinted days on the tablet dispenser. She starts taking one tablet daily, beginning with the first tablet in the top row. The patient completes her tablet regimen when she has taken the last tablet in the tablet dispenser.
She will then take no tablets for a week 7 days. For all subsequent cycles, the patient begins a new tablet regimen on the eighth day after taking her last tablet, again starting with the first tablet in the top row after placing the appropriate day label strip over the preprinted days on the tablet dispenser.
Following this regimen of 21 days on—7 days off, the patient will start all subsequent cycles on the same day of the week as the first course. Likewise, the interval of no tablets will always start on the same day of the week.
Tablets should be taken regularly with a meal or at bedtime. It should be stressed that efficacy of medication depends on strict adherence to the dosage schedule.
Special Notes on Administration Menstruation usually begins two or three days, but may begin as late as the fourth or fifth day, after discontinuing medication.
If spotting occurs while on the usual regimen of one tablet daily, the patient should continue medication without interruption. Two consecutive tablets are missed week 3 Sunday-Start Regimen:. The possibility of ovulation occurring increases with each successive day that scheduled tablets are missed. While there is little likelihood of ovulation occurring if only one tablet is missed, the possibility of spotting or bleeding is increased.
This is particularly likely to occur if two or more consecutive tablets are missed. In the rare case of bleeding which resembles menstruation, the patient should be advised to discontinue medication and then begin taking tablets from a new tablet dispenser on the next Sunday or the first day Day 1 , depending on her regimen.
Persistent bleeding which is not controlled by this method indicates the need for reexamination of the patient, at which time nonfunctional causes should be considered. The ferrous fumarate tablets are present to facilitate ease of drug administration via a day regimen and do not serve any therapeutic purpose.
There is no need for the patient to count days between cycles because there are no "off-tablet days. Sunday-Start Regimen: The patient begins taking the first light-colored tablet from the top row of the dispenser labeled Sunday on the first Sunday after menstrual flow begins. When the menstrual flow begins on Sunday, the first light-colored tablet is taken on the same day.
The patient takes one light-colored tablet daily for 21 days. The last light-colored tablet in the dispenser will be taken on a Saturday. Upon completion of all 21 light-colored tablets, and without interruption, the patient takes one brown tablet daily for 7 days. Upon completion of this first course of tablets, the patient begins a second course of day tablets, without interruption, the next day Sunday , starting with the Sunday light-colored tablet in the top row.
Adhering to this regimen of one light-colored tablet daily for 21 days, followed without interruption by one brown tablet daily for seven days, the patient will start all subsequent cycles on a Sunday. Day-1 Start Regimen: The first day of menstrual flow is Day 1. She starts taking one light-colored tablet daily, beginning with the first light-colored tablet in the top row. After the last light-colored tablet at the end of the third row has been taken, the patient will then take the brown tablets for a week 7 days.
For all subsequent cycles, the patient begins a new 28 tablet regimen on the eighth day after taking her last light-colored tablet, again starting with the first tablet in the top row after placing the appropriate day label strip over the preprinted days on the tablet dispenser. Following this regimen of 21 light-colored tablets and 7 brown tablets, the patient will start all subsequent cycles on the same day of the week as the first course.
Special Notes on Administration Menstruation usually begins two or three days, but may begin as late as the fourth or fifth day, after the brown tablets have been started. In any event, the next course of tablets should be started without interruption.
If spotting occurs while the patient is taking light-colored tablets, continue medication without interruption. If the patient forgets to take one or more light-colored tablets, the following is suggested:. The possibility of ovulation occurring increases with each successive day that scheduled light-colored tablets are missed.
While there is little likelihood of ovulation occurring if only one light-colored tablet is missed, the possibility of spotting or bleeding is increased. This is particularly likely to occur if two or more consecutive light-colored tablets are missed. If the patient forgets to take any of the seven brown tablets in week four, those brown tablets that were missed are discarded and one brown tablet is taken each day until the pack is empty.
A back-up birth control method is not required during this time. A new pack of tablets should be started no later than the eighth day after the last light-colored tablet was taken.
In the rare case of bleeding which resembles menstruation, the patient should be advised to discontinue medication and then begin taking tablets from a new tablet dispenser on the next Sunday or the first day Day-1 , depending on her regimen.
If the patient has not adhered to the prescribed dosage regimen, the possibility of pregnancy should be considered after the first missed period and oral contraceptives should be withheld until pregnancy has been ruled out. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out before continuing the contraceptive regimen.
After several months on treatment, bleeding may be reduced to a point of virtual absence. This reduced flow may occur as a result of medication, in which event it is not indicative of pregnancy.
