Question 1

i have 3 more pills of bactrim (sulfamethoxazole and trimethoprim) to take - how long until my coc (yaz) is fully effective again? should i use a secondary method of contraception?

Accepted Answer

Yes: Trimethoprim, one of the ingredients in bactrim (sulfamethoxazole and trimethoprim), (sulfamethoxazole and trimethoprim) mildly induces the liver to process the hormones in birth control pills faster, theoretically reducing their effectiveness. The half life of bactrim (sulfamethoxazole and trimethoprim) is only 8-10 hours but the enzymes that are induced take longer to return to normal levels. The usual recommendation is to use a backup method for 7 days after finishing bactrim (sulfamethoxazole and trimethoprim).

Question 2

my girlfriend is on yaz plus. she normally takes her pill every morning but sometimes forgets and takes at night. is it still effective?

Accepted Answer

Not as effective: Because the oral contraceptive pill relies on artificial hormone levels to prevent ovulation, any change in the regular schedule of taking the pill may lessen its effectiveness. A better option if this happens frequently is the Depo Shot which is administered every 3 months or the implant which can last up to 3 years and the hormonal IUD can last 3-5 years.

Question 3

im on yaz and have a bmi of 27. does my weight make the pill less effective?

Accepted Answer

Obesity &amp; O.C.'s: Oral contraceptive hormone pills are impacted by obesity and BMI's in excess of 30. A BMI of 27 is considered overweight and not yet obese and this is a good time to reduce the BMI. The theory as to  why obesity impacts the pill, is that the peripheral fat can and does make hormones that feedback to the pituitary gland just as the contraceptive pill does and interferes with its' action.

Question 4

good day does taking metsyn x sachets and yaz plus still allow yaz plus to be effective as a contraceptive.

Accepted Answer

Yes: There should be no interaction between these. Although it probably doesn't matter if you take them together, as a precaution I would avoid that. Obviously, the Yaz Plus is less effective if not taken consistently and at around the same time each day.

Question 5

how long would it take until yaz (drospirenone and ethinyl estradiol) birth control is effective against pregnancy?

Accepted Answer

1 month: The standard recommendation is to use a back-up method of birth control (condoms) for one month of taking the pill before relying on it to be effective.

Question 6

iud vs. yaz (drospirenone and ethinyl estradiol) 28- which is more effective for pregnancy prevention and also for endometriosis?

Accepted Answer

Iud: both methods have been shown to be associated with relief of pain related to endometriosis, however the most effective method for birth control is the IUD, hands down. There are fewer concern about compliance with the IUD and it may have a better local effect on controlling endometriosis. I would be happy to discuss more in consultation.

Question 7

one hour after taking yaz (drospirenone and ethinyl estradiol) pill i had a bowel movement that was soft but not diarreah is the pill still effective?

Accepted Answer

Yes: Oral contraceptives are metabolized in the liver. Having diarrhea, soft stools, or constipation, will not affect their effectiveness.

Question 8

hi! im on yaz birth control pill and i want to drink linden tea because of my throat and my cough. is it ok to drink linden tea on birth control and does it interferes with it? it wouldnt make it less effective right?

Accepted Answer

: There is no known scientific evidence of linden tea affecting any medication. So enjoy your tea.

Question 9

are the active yaz plus pills the same?

Accepted Answer

Yes: Yaz has 24 active pills that all have the same amount of 2 ingredients (two hormonal medications in each pill - 3 mg of drospirenone and 0.02 mg of ethinyl estradiol). There are 4 inactive pills, to make a total of 28 pills in the pack.

Question 10

how long does it take yaz to work its way out of your system?

Accepted Answer

4 days: then you should expect ovulation roughly 2.5 weeks, 4 weeks for 1st period, after stopping Yaz. If not ovulating/period this could be from polycystic ovarian syndrome that may preexist the use of Yaz. Of course, pregnancy may happen with ovulation timing of intercourse.
