Here Are Answers to Some of Your Questions:


Does the Pill Really Help Get Rid of Acne?

Some hormone birth control methods, in addition to being highly effective contraceptives, can actually provide additional non-contraceptive benefits. Certain combination birth control pills have been very successful at treating acne. In some cases, the Ortho Evra Patch has also helped control acne breakouts.

Since there are so many myths about the pill floating around, it is important that you understand this method before you choose to use it. As with any medication, not all women will react the same way when using the pill. That being said, it is a popular option given its effectiveness as well as its potential additional benefits.


Does the Progestin Type in My Pill Actually Matter?

There are eight types of progestin that can be found in combination birth control pills. The blend of estrogen amount with each progestin type can affect your body chemistry differently. The variations in estrogen/progestin combinations may also offer slightly different benefits and/or side effects.

It is difficult to compare pill brands because they may use different types and strengths of progestin. So, even if two brands have the same type of progestin, they have different amounts. Due to this, the potency of each pill can widely vary.

Having some knowledge about progestin differences as well as about estrogenic effects (level of estrogen activity), androgenic effects (the progestin’s potential to cause side effects) and progestational selectivity (how the progestin fuels progesterone receptors) may help you and your doctor choose the best pill brand for you. Understanding how progestin and estrogen combinations work may help to minimize specific side effects by switching to or initially choosing a particular pill brand.


Am I Dreaming or Have I Gained 10 Pounds Since Starting Depo Provera?

This is one of the questions I am asked all the time. Women want to know the truth - does using Depo Provera cause weight gain?

Though you may not want to hear it, weight gain is commonly cited as a reason why many women stop their Depo use. Research shows that Depo Provera use is linked to significant weight gain, but the actual degree of weight increase can depend on how long you have used the product. The longer you use it, the more weight you may gain. Clinical trials report that you could expect a weight gain of about five pounds during the first year of use, and this could go up higher with each subsequent year.


Why Do I Need to Take the Pill at the Same Time Every Day?

To answer this question, you need to know a little bit about ethinyl estradiol. Your birth control pill contains ethinyl estradiol -- a manmade form of estrogen. Your body (more specifically, your liver) has the ability to break down ethinyl estradiol very quickly. Because this hormone is metabolized very fast, you need to add more of it into your body every day to ensure that there is enough estrogen to stop your body from ovulating. When you forget to take a pill, the pill’s effectiveness can be compromised because there may not be enough ethinyl estradiol in your system. Generally speaking, most birth control pills have about a 1- to 2-hour window period where effectiveness is not lowered. This means that although you should strive to take your pill at the same time each day, you have about a 1-2 hour grace period (so, if you normally take your pill at 8:00 PM, you can realistically take it anywhere between 6:00 PM until 10:00 PM). Keep this in mind when traveling between time zones as well as during time changes.


Doesn't the Mirena IUD Cause Infertility?

Unfortunately, poorly conducted IUD studies from the 1970s and 1980s have led many women to come to this erroneous conclusion that IUD use increases your risk of infertility or pelvic inflammatory disease (PID). These studies were not properly carried out, and their claims do not appear to be true. In fact, present-day research reveals that IUD use (whether in the past or current) is not related to an increased risk of tubal blockage (one of the common causes of infertility). Studies also show that PID occurrence in women using IUDs is extremely low and is similar to PID incidence in the general population. The Mirena IUD may actually lower your PID risk.

The World Health Organization backs up this research -- its official stance is that there’s no increased risk of infertility among IUD users who are in stable, monogamous relationships. That being said, it is thought that infertility (due to tubal blockage) can be a result from an untreated sexually transmitted infection. So remember, IUDs don’t protect against STDs. If you have several sexual partners or do not know the sexual history/health status of your current partner, in addition to your IUD, it may be a good idea to use condoms to protect yourself from contracting an STD.
