Too many pounds can impact effectiveness of some forms of contraception

Updated: May 29, 2014 4:30PM

Did you know that your weight might increase your chance of unwanted pregnancy?

A new European study has found that emergency contraceptive becomes less effective as a woman’s weight increases. The study found that emergency contraceptive starts to lose its effectiveness if a woman is 165 pounds or above, and it is greatly compromised — with what’s described as an “absence of effectiveness” — at around 176 pounds.

Although the study was performed on a French drug, the emergency contraceptive in question is identical to Plan B here in the United States. Teva, the company that makes Plan B, has yet to comment on the findings.

Sadly, the search for effective and safe contraception is not over. In fact, recent data from the National Center for Health Statistics found that some women try up to five different forms of birth control before they find one that works for them and their body. And, Plan B is a popular option. According to new data released by the National Center for Health Statistics, 5.8 million women report that they have used the morning after pill on more than one occasion.

But the good news is that birth control options are plentiful (such as the IUC, hormonal birth control, diaphragms, etc.) but you might need to try a few different methods of contraception before you find the method that best works for you. And, no method is foolproof, so know your options as well as the limitations of your options. Ask your doctor how effective your form of contraception is and learn if there are other choices that might be more effective for your body and your lifestyle.

And, as always, Plan B is definitely a plan b — especially for women who are 165 pounds or up.
