What things contradict birth control?

Question

I know if you take antibiotics or St. John's Wart, it lowers the effect of birth control. What else can do this? Thanks!

Smoking may affect my body in other ways, but it has nothing to do with how the pill works, already checked that out. Thanks though.

Answer 1

Antibiotics and other antiinfectives such as Diflucan lessen the effectiveness of oral contraceptives.
Smoking increases the risks of blood clots.

Thyroid hormone drugs, certain benzodiazepines (e.g., diazepam, chlordiazepoxide), prednisone-like drugs, certain antidepressants (e.g., tricyclics), beta-blockers (e.g., metoprolol), "blood thinners" (anticoagulants such as warfarin), insulin. BCP can affect the results of certain lab tests (e.g., thyroid). Inform all laboratory personnel that you use this drug.
Birth control pills may significantly intensify the effects of alcohol.
You should always talk to your pharmacist before taking herbals, OTC, or other medications.

Answer 2

Ok...I'll answer these questions according to my experience (I'm 32 and have been on the Pill since I was 18.) 1.Birth control makes you gain weight-- I gained 5 lbs. 2.Birth control just increased your appetite-- not for me. 3.Birth control makes you breasts grow an entire cup size-- my breasts did grow, but I'm not sure if i can attribute it completely to the pill.....went from a C to a D. 4.Birth control clears up acne-- YES. 5.Birth control causes acne-- NO 6.Birth control tricks your body into thinking its pregnant-- YES 7. pregnancy tests come out positive while on it-- NO 8.You won't be able to fit into any of your old clothes--NO 9. It reduces PMS--YES 10. shorter periods-- YEs...went from 7 day periods to 4 day periods. Although, keep in mind it will take your body about 4-6 months to get used to synthetic hormones. You may have a slight breakout or irregular period until your body adjusts to the Pills.

Answer 3

Less effective...taking at a different time every day or missing a dose anytime in the cycle will make it very ineffective.

Smoke and are older than 35
Have diabetes and are older than 35
