Which pills have higher progestin side effects or cause more acne and hair growth?
Each progestin has a different potency, milligram per milligram, in terms of progesterone effect to stop menstrual bleeding or androgen effect to stimulate acne and hair growth. However you must remember that a higher potency progestin may be used in a much smaller milligram dose and thus be equivalent to a larger milligram dose of a less potent progestin. For example, desogestrel is a very potent and androgenic progestin but its usual oral contraceptive dose is 0.15 mg instead of 1.00 mg for norethindrone. Its progestin potency compared to norethindrone would be 0.15 X 9.0 = 1.35 times. For androgenicity, it would be 0.15 X 3.4 = .51 or half as androgenic as a pill containing 1 mg of norethindrone.
Progestin Potency of Different Oral Contraceptive Progestins* Progestin Progestational Activity
(relative to 1 mg of norethindrone) Androgenic Activity
(relative to 1 mg of norethindrone)
norethindrone 1 mg 1.0 1.0
norethrindrone acetate 1 mg 1.2 1.6
ethynodiol diacetate 1 mg 1.4 0.6
levonorgestrel 1 mg 5.3 8.3
dl-norgestrel 1 mg 2.6 4.2
norgestimate 1 mg 1.3 1.9
norelgestromin 1 mg** 1.3 1.9
desogestrel 1 mg 9.0 3.4
drospirenone 1 mg 1.5 0.0
* - From Table 2 in Dickey RP: Individualizing oral contraceptive therapy. OBG Management Supplement October 2000, p 5.
** - Not yet tested but it is the major active metabolite of norgestimate
The pills that are likely to cause worse acne and hair growth side effects are those pills high in androgenicity and low in estrogen content. Such pills might include:
Loestrin® 1.5/30
Loestrin® 1/20 Fe
Estrostep® Fe
Levlen®
Alesse®
Ovral®
Norlestrin® 1/50
Keep in mind that MOST women on these above pills DO NOT have acne problems, just those that have a tendency toward androgenicity.
What pills would be better for ...?
In order to classify an oral contraceptive as an estrogen dominant, progestin dominant or androgenic pill, you must multiply the actual dose of the components times the relative potency of that component. Keep in mind that these are relative classification and do not always hold from one woman to another. For different oral contraceptive side effects, you might consider switching to the pills indicated in the table below to minimize those side effects.

Where can I get free or discounted birth control pills?
Planned Parenthood organizations and your local county Public Health Department often provide birth control pills on an ability to pay discounted scale. If you qualify, they may even be free. Look up in the yellow pages phone directory for the Planned Parenthood or Public Health Department for the county you live in. Give them a call and ask about the costs of pills. If you are in college either full or part time, you may also be qualified to use the student health facility and often they provide oral contraceptives at cost or a discount.
When your doctor prescribes a given oral contraceptive, most of the time they indicate it can be filled with a generic equivalent. If not, ask the doctor to please do that or ask the nurse to have a prescription rewritten for a generic equivalent. There are sources on the Internet that will except mailed-in prescriptions and the cost of a generic equivalent is often in the $12-15 range. I have not used them but you may want to check out Hocks Drugs or use a search engine to look for "discount birth control".
