Hi Deno!

As far as I know.......when a dosage of birth control is lowered......it is to the benefit of the woman. Oral contraceptive, if taken properly, is a very effective contraceptive indeed!

However, there are reasons why "the pill" may not be 100%! Something as obscure as an antibiotic (like when you have an impacted tooth for example) can change the effectiveness of the pill and make it null! A lower dosage is still a dosage until something interrupts that flow. One missed pilll can and has resulted in pregnancy. Besides certain antibiotics, there are other chemical interactions that may make the pill ineffective! Check the web.......or ask your (her) doctor for all the info you can get!

Good Luck Hun! Hope this helped!
