Choosing the Right Birth Control Pill

With so many combination birth control pills available, how do you know which is the best one for you in order to minimize birth control effects? Combined oral contraceptives contain an estrogen and a progestin. Eight progestin types are used in the pill. Knowing the differences between the progestins and about estrogenic effects, androgenic effects and progestational selectivity, can help minimize the pill's side effects. Use this guide in choosing a combination birth control pill or to pick a different pill brand to help lessen a birth control effect that you may be experiencing.

A Quick Explanation About Choosing a Birth Control Pill:

To briefly explain how the combination of these activities may cause side effects, let's look at some specific combination birth control pills. Oral contraceptives that tend to have high androgenic effects and low estrogen activity, for example, are more likely to cause unwanted hair growth and acne side effects. Additionally, a progestin with higher androgenicity will also tend to produce less breast tenderness, bloating and mood changes. It is important to remember, though, that the majority of women using a pill with this combinations do not end up developing acne; this side effect is more likely to occur in those women who have a tendency toward androgenicity. Birth control pills containing this high androgenic/low estrogenic pattern include:

  • Alesse
  • Estrostep FE
  • Levlen
  • Loestrin 1.5/30
  • Loestrin 1/20 Fe
  • Ovral

Since there are different types of progestins, they each have a different potency in terms of progestational, estrogenic, and androgenic effects. The result of these effects is dependent on the combination of the type and levels of progestin and estrogen. Although a specific pill brand may have certain characteristics due to its estrogen and progestin dose and potency for androgenic effects, women may respond differently to these components. Therefore, please note that the following are general guidelines, and may not apply to all women.

To be a little more technical, in order to determine the total combination of these three effects, a person needs to multiply the actual dose of these three components (effects) times the relative potency of that component in order to classify a birth control pill brand as having high androgenic effects, being estrogen dominant, or progestin dominant. Given the complexity of figuring this out on your own, the decision as to which birth control pill to use should be discussed with your healthcare provider. This information is not intended to be a substitute for that discussion. You can use this information to begin a conversation with your healthcare provider about which pill type may be best for you.

It is also important to give the pills you are currently taking a fair trial of at least 2 to 3 months. If your pills are switched, you should also give the new ones a 2- to 3-month trial because it often takes a few months just for your body to adjust to the estrogen and progestin in a combination birth control pill.

Choosing a Birth Control Pill by Minimizing Its Side Effects:

With that being said, you can now try to determine what pills brand may be best for you. Just another reminder, the following chart is a relative classification, so it may not apply to every female. When choosing a combination birth control pill, you may be able to minimize side effects by switching to (or initially picking) a pill brand suggested in the below chart based on which side effect you are trying to lessen or alleviate.

Breast soreness lower estrogen, lower progestin potency Alesse, Levlite

(used either continuously with no days of placebo pills or with only 4 days of placebo pills for prevention)

Headaches (not menstrual migraines)

lower estrogen, lower progestin potency

Alesse, Brevicon, Levlite, Modicon, Necon 1/35, Ortho-Cyclen, Othro-TriCyclen, Ovcon 35 , Tri-Levlen, Triphasil, Trivora

Moodiness or irritability

lower progestin potency

Alesse, Levlite, Loestrin 1/20 Fe, Yasmin,

(or any pill with less estrogen than currently on)

Severe menstrual cramps higher progestin potency Demulen 1/35, Demulen 1/50, Desogen, Mircette, Loestrin 1.5/30, Ortho-Cept, Yasmin, Zovia 1/35E, Zovia 1/50E

Weight gain

lower estrogen, lower progestin potency

Alesse, Levlite, Loestrin 1/20 Fe, Yasmin,

(or any pill with less estrogen than currently on)

**Estrostep FE contains the progestin norethindrone acetate (this progestin typically has a higher androgen potency). Therefore, although Estrostep FE follows more of a high androgenic/low estrogenic pattern, this brand is a triphasic pill that was actually designed to help prevent breakthrough bleeding while attempting to keep hormone exposure as low as possible. Estrostep FE is a good example as to why the information in this chart should be viewed more in terms of being general guidelines, and may not always hold from one woman to another.
