Patch higher estrogen than pill?
| Sun, 04-18-2004 - 5:43pm |
I'm a little confused because I was on the Nuva Ring site in case the patch doesn't work for me, and found a comparison between the pill, patch, and Nuva Ring. It indicated, unless I read it wrong, that that patch put more estrogen into your system than the pill did? Is this correct? I thought that the patch had 20 mcg of estrogen while the pill ranged from either 20 mcg to about 35 mcg or more of estrogen. Would that not make the patch lower in total estrogen or is it different because of the way it's absorbed or because you leave it on all day?
Thanks for any responses. And if this already posted, I'm sorry, I tried to do it earlier, but didn't see it on the board.

Hi sc,
The patch releases ~20mcg of estrogen per day, which puts it on par with 'ultra low dose' pills.
I can sympathize - it's in my family as well.
Personally, I don't intend to have a mammogram until they've come up with a device that can scan the breast without slamming it in between two metal plates!!! For us small-chested people, that's dang near impossible! Furthermore, as my mom put it, if testing for testicular cancer involved slamming a guy's testicles in between two cold metal plates repeatedly, some guy would have come up with a better process by now. I'm holding out for that better process! And as for breast self-exams, heck - mine are so small I'd probably SEE a lump before I could feel it! LOL
I know, I know, I'm bad. Just had to rant.

hehe...you're cracking me up, Caitlin.
To get back on topic Mandy, these quotes are from the perscribing info for Ortho Evra:
"Following application of ORTHO EVRA ® , both norelgestromin and EE rapidly appear in the serum, reach a plateau by approximately 48 hours, and are maintained at an approximate steady-state throughout the wear period. C SS concentrations for norelgestromin and EE during one week of patch wear are approximately 0.6-0.8 ng/ml and 40-50 pg/ml, respectively, and are generally consistent from all studies and
application sites. These C SS concentrations are within the reference ranges for norelgestromin (0.6 to 1.2 ng/ml) and EE (25 to 75 pg/ml) established based upon the Cave concentrations observed with subjects taking ORTHO-CYCLEN ®."
"Daily absorption of norelgestromin and EE from ORTHO EVRA ® was determined by comparison to an intra-venous infusion of norelgestromin and EE. The results indicated that the average dose of norelgestromin and EE absorbed into the systemic circulation is 150 mcg/day and 20 mcg/day, respectively."
Which of them estrogen blood serum levels or daily absorption do you think are most important as far as side effects go?

Thanks Jill!
Yeah, I panic too much about estrogen, I think, but I'm scared of breast cancer and my periods and cramps were soooo horrible before the pill and patch that I can't imagine having to go back to not having any hormonal contraception. The whole reason I was originally put on it was because they were so bad I would have miss school and stuff. It felt reassuring to know that some of you have some of the same histories and that you went ahead and got on it, also.
At any rate, thanks again for all of your information. I appreciate it.
