When facing an endless list of contraceptive drugs, do you feel helpless in finding a suitable one for you?  Do not worry.  Here are a few basics of birth controls which will give you some knowledge to begin with to make an informed decision.

How do contraceptives work?
All contraceptive drugs contain either a progestin alone or a progestin with an estrogen, both of which are female sex hormones.  Extra female sex hormone(s) in combination or alone prevent pregnancy by inhibiting egg production and/or fertilization. 

What are the differences between mini-pills and combination pills?
Progestin-only oral contraceptives are also known as the "mini-pills".  Mini-pills are less forgiving compared to estrogen/progestin combination pills.  Mini-pills must be taken the same the time every day and must be used with another contraceptive method for a month before one can solely rely on them.  Combination pills only need to overlap with a sec

ondary method for 7 days if one starts on the Sunday following a period.  If you miss a dose of a mini-pill, or take the mini-pill more than 3 hours late than the scheduled time, you should use a backup method until the next period; whereas if you miss a dose of a combination pill, you can double the dose on the next day.

Who should be on mini-pills?
Mini-pills are a suitable choice for women who are breast-feeding; who need short- or long-term birth control that can be stopped at any time; who cannot take estrogen, including smokers older than 35, long-standing, poorly controlled diabetics, heart disease, hypertension and clotting dysfunction patients.  Other candidate populations include those who have migraine headache and those who have heavy, painful menstrual periods.  Examples of mini-pills include Ortho Micronor®, Errin™, Provera®, etc. 


What are other contraceptive formulations?
Several non-oral birth controls are available.  A clear advantage of non-oral birth controls is that they do not need to be administered daily.  Depo-Provera® is a progestin shot which provides 3 month of contraceptive protection.  Ortho EVRA™ is a transdermal contraceptive patch.  Three patch systems provide contraceptive coverage for a cycle, with each system worn for 7 days.  A vaginally inserted system, NuvaRing®, needs to be left in place for 3 weeks in a cycle.  This list does not cover all the non-oral formulations.  Ask you doctor or pharmacist for more options.
