Question 1

friday i found out i have a uti, and was prescribed macrobid, i had unprotected sex saturday and im on birth control. i also took phenazopyridine on saturday morning and monday morning. do these affect the effectiveness of birth control? am i safe?

Accepted Answer

: You're entirely safe. The business about antibiotics interfering with birth control pills or other hormonal contraceptions is almost an urban myth. It is exceedingly rare and doesn't occur at all with most antibiotics. Nitrofurantion (Macrobid) has no such effect. Phenazypyridine isn't an antibiotic and also has no effect.

Question 2

can macrobid wipe out birth control?

Accepted Answer

No: Macrobid would not affect any form of contraception.

Question 3

does macrobid interact with tri-estarylla birth control? do i need to use a backup method? if so how long and when?

Accepted Answer

: Antibiotics have been known to interfere with the effectiveness of oral contraceptives. It would be wise to use a backup method such as condoms, spermicide or diaphragm to prevent pregnancy during the treatment period.

Question 4

can macrobid cause breakthrough spotting while on birth control pills?

Accepted Answer

Macrobid: Yes, Macrobid is known to cause breakthrough bleeding while on the pill

Question 5

i took macrobid for 5 days during my placebo week of my birth control. i only took it during the placebo week. am i still protected?

Accepted Answer

No worries!: Nitrofurantoin (Macrobid®) and other antibiotics have no effect on birth control pills. There is slight risk with a few antibiotics, e.g. rifampin (mostly used against tuberculsosis). You needn't worry at all. See https://www.drugs.com/article/antibiotics-and-birth-control.html

Question 6

does macrobid affects birth control pill? if so, how long does it stay in my system and not use condom?

Accepted Answer

BC pills should work: The current thinking is that except for rifampin, other commonly-used antibiotics such as Macrobid do not alter the effectiveness of birth control pills. This is likely presuming a person is not sick with vomiting or bad diarrhea, or some other condition that decreases the absorption of a swallowed pill. One can look up:  http://www.ncbi.nlm.nih.gov/pubmed/12063491

Question 7

i have been having blood in my discharge for 5 days after taking macrobid, is my birth control pill still effective?

Accepted Answer

BC pills should work: The current thinking is that except for rifampin, other commonly-used antibiotics do not alter the effectiveness of birth control pills such as Aviane. This is likely presuming a person is not sick with vomiting or bad diarrhea, or some other condition that decreases the absorption of a swallowed pill. One can look up:  http://www.ncbi.nlm.nih.gov/pubmed/12063491

Question 8

how long after taking generic antibiotic for macrobid do you need to use a back up birth control method like a condom?

Accepted Answer

One cycle: If you have had a period since stopping the antibiotic, and are taking a contraceptive you need not use a condom to prevent pregnancy. However using a condom, unless you are in a committed monogamous relation is a good idea.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. 
Practice safe sex, if you have sex. 
Get HPV vaccine

Question 9

if taken for 3 days, how long does macrobid stay in your body and effect birth control (alesse) or emergency contraceptive (taken 7 days later) use ?

Accepted Answer

Not a factor...: Macrobid won't affect birth control or emergency contraception effectiveness.  Best wishes

Question 10

will macrobid mess up your period while on the birth control pill?

Accepted Answer

Nope: Nitrofurantoin (Macrobid) gives very low blood levels -- it's the high urine levels that cure urinary tract infections. (There is no reason other than UTI to take Macrobid.) It has no effect on menstruation and doesn't interfere with effectiveness of birth control pills.
