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 the lowest 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.
