-
- INGREDIENTS
-
- estrogens and progestins
-
- DOSAGE FORM
-
- Tablets (in packages of 21 or 28 tablets; when 28 tablets are present,
- seven of the tablets either are placebos or contain iron)
-
- STORAGE
-
- Oral contraceptives should be stored at room temperature. They should be
- kept in their original container, which is designed to help you keep track of
- your dosing schedule.
-
- USES
-
- Oral contraceptives change the hormone balance of the body to prevent
- pregnancy.
-
- TREATMENT
-
- To avoid stomach irritation, you can take oral contraceptives with food
- or with a full glass of water or milk.
- In order to become accustomed to taking this medication, try to take it
- at the same time every day.
- Use a supplemental method of birth control for the first week after you
- start taking oral contraceptives (the medication takes time to become fully
- effective).
- Even if you do not start to menstruate on schedule at the end of the pill
- cycle, begin the next cycle of pills at the prescribed time. Many women
- taking oral contraceptives have irregular menstruation.
- If you miss a dose of this medication and you are on a 21-day schedule,
- take the missed dose as soon as you remember. If you don't remember until the
- next day, take the dose of that day plus the one you missed; then return to
- your regular dosing schedule. If you miss two days' doses, you should take
- two tablets a day for the next two days; then return to your regular dosing
- schedule. You should also use another form of birth control during those four
- days. If you miss your dose three days in a row, you should stop taking this
- drug and use a different method of birth control until you check with your
- doctor. Your doctor may want you to start a new package seven days after the
- last tablet was missed and use an additional method of birth control until the
- start of your next period. If you are on the 28-day schedule and you miss
- taking any one of the first 21 tablets, you should follow the instructions for
- the 21-day schedule. If you missed taking any of the last seven tablets,
- there is no danger of pregnancy, but you should take the first pill of the
- next month's cycle on the regularly scheduled day.
-

- Minor.
-
- Abdominal cramps, acne, backache, bloating, change in appetite, changes
- in sexual desire, diarrhea, dizziness, fatigue, headache, nasal congestion,

- flow; chest pain; depression; difficult or painful urination; enlarged or
- tender breasts; hearing changes; increase or decrease in hair growth; migraine

- INTERACTIONS
-
- These drugs interact with several other types of drugs:
- 1. Pain relievers, antimigraine preparations, rifampin, barbiturates,
- phenylbutazone, phenytoin, primidone, carbamazepine, isoniazid, neomycin,
- griseofulvin, penicillins, tetracycline, chloramphenicol, sulfonamide
- antibiotics, nitrofurantoin, and ampicillin can decrease the effectiveness of
- oral contraceptives.
- 2. Oral contraceptives can reduce the effectiveness of oral
- anticoagulants (blood thinners, such as warfarin), anticonvulsants, tricyclic
- antidepressants, antihypertensive agents, oral antidiabetic agents, and
- vitamins.
- 3. Oral contraceptives can increase the blood levels of caffeine,
- diazepam, chlordiazepoxide, metoprolol, propranolol, adrenocorticosteroids
- (cortisone-like medications), imipramine, clomipramine, phenytoin, and
- phenylbutazone, which can lead to an increase in side effects.
- 4. Oral contraceptives can decrease the blood levels and, therefore, the
- effectiveness of lorazepam and oxazepam.
- BE SURE TO TELL YOUR DOCTOR about any medications you are currently
- taking, especially those listed above.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to estrogens, progestins, or progesterones.
- * Before starting to take this medication, be sure to tell your doctor if
- you now have or if you have ever had asthma, bleeding problems, breast cancer,
- clotting disorders, diabetes mellitus, endometriosis, epilepsy, gallbladder
- disease, heart disease, high blood pressure, kidney disease, liver disease,
- mental depression, migraine headaches, porphyria, strokes, thyroid disease,
- uterine tumors, vaginal bleeding, or vitamin deficiencies.
- * Some women who have used an oral contraceptive have had difficulty
- becoming pregnant after discontinuing use. Most of these women had had scanty
- or irregular periods before starting oral contraceptives. Possible subsequent
- difficulty in becoming pregnant is a matter you should discuss with your
- doctor before using an oral contraceptive.
- * Every prescription comes with a booklet that explains birth control
- pills. Read this booklet carefully. It contains exact directions on how to
- use this medicine correctly and describes the risks involved.
- * Women over 30 years of age and women who smoke while taking this
- medication have an increased risk of developing serious heart or blood vessel
- side effects.
- * If this drug makes you dizzy, avoid taking part in any activity that
- requires alertness, such as driving a car or operating potentially dangerous
- machinery.
- * Before surgery or other medical or dental treatment, tell your doctor
- or dentist you are taking this drug.
- * This type of drug has been suspected of causing cancer. If you have a
- family history of cancer, you should consult your doctor before taking oral
- contraceptives.
- * Be sure to tell your doctor if you are pregnant. Oral contraceptives
- have been associated with birth defects in animals and in humans. Because
- hormones have long-term effects on the body, oral contraceptives should be
- stopped at least three months prior to becoming pregnant. Another method of
- birth control should be used for those three months. Also, tell your doctor
- if you are breast-feeding an infant. This medication passes into breast milk.
