How should I start and take my oral contraceptive?
Dosage is 1 tablet daily for 28 consecutive days.
Dose should be taken at the same time each day, either after the evening meal or at bedtime.
Dosing may be started on the first day of menstrual period (Day 1 starter) or on the first Sunday after the onset of the menstrual period (Sunday starter).
Day 1 starter: Dose starts on first day of menstrual cycle taking 1 tablet daily.
Sunday starter: Dose begins on first Sunday after onset of menstruation; if the menstrual period starts on Sunday, take first tablet that very same day. With a Sunday start, an additional method of contraception should be used until after the first 7 days of consecutive administration.
What should I do if I don't have a menstrual cycle (period)?
If all doses have been taken on schedule and one menstrual period is missed, continue dosing cycle.
If two consecutive menstrual periods are missed, pregnancy test is required before new dosing cycle is started.
If doses have been missed during the first 3 weeks (the non-sugar pills/non-period week) and the menstrual period is missed, pregnancy should be ruled out prior to continuing treatment.
What should I do if I miss a dose of my oral contraceptive?
Missed doses (monophasic formulations) (refer to package insert for complete information):
One dose missed:
Take as soon as remembered or take 2 tablets next day
Two consecutive doses missed in the first 2 weeks:
Take 2 tablets as soon as remembered or 2 tablets next 2 days.
An additional method of contraception should be used for 7 days after missed dose.
Two consecutive doses missed in week 3 or three consecutive doses missed at any time:
An additional method of contraception must be used for 7 days after a missed dose.
Day 1 starter: Current pack should be discarded, and a new pack should be started that same day.
Sunday starter: Continue dose of 1 tablet daily until Sunday, then discard the rest of the pack, and a new pack should be started that same day.
Any number of doses missed in week 4:
Continue taking one pill each day until pack is empty; no back-up method of contraception is needed
Is it okay to store my birth control pills in the bathroom?
- Keep away from moisture (thus, bathroom not the best place)
- Keep away from excessive heat or light
I am spotting between cycles. Is this normal?
Hormonal birth-control methods can cause spotting. Birth-control pill users can experience spotting if they miss a pill or if the hormone levels in their particular type of pill are not high enough.
Vaginal bleeding: Presentation of irregular, unresolving vaginal bleeding warrants further evaluation including endometrial sampling, if indicated, to rule out malignancy; evaluate hypothalamic-pituitary-function in women with persistent (≥6 months) amenorrhea (especially associated with breast secretion) following discontinuation of therapy.
Do I have to take the sugar pills on the last week?
You don't have to take the sugar pills, but they keep you in the habit of taking your medication every day.
You can also skip the sugar pills and go onto a new pack to completely skip your period. However, this should only be done under the direction of your physician because generally, it is healthy for your body to bleed at least three to four times a year.
One reason people don't skip the sugar pills and go through menstruation is as a confirmation that their birth control is indeed working. (ie, if you stop taking the pill, and you don't have your period, you may be pregnant) While this is not a foolproof way to confirm the efficacy of your birth control, it certainly is practical. (It's actually possible to have your period and still be pregnant, but this very rarely happens.)
It's important to know that you should only skip the inactive pills if you are taking monophasic birth control pills. (This just means that each of the pills that you're taking has an equal amount of the active ingredients in each of them. Some birth control pills work by increasing the estrogen week by week, so you shouldn't skip your period if you're on this type of pill.) Examples of monophasics include Alesse, Brevicon, Demulen, Desogen, Genora, Levlen, Levlite, Loestrin, Lo/Ovral, ModiCon, Necon, Nordette, Norethin, Norinyl, Ortho-Cyclen, Ortho-Novum, Ovcon, Ovral, Portia and Zovia.Check with your doctor to see how long you should/can skip inactive pills.
Some gynocologists recommend taking inactive pills once every 3-4 months (which means you'd have your "period" 3-4 times a year).
