Quoting Noah"s Mommy :" <blockquote><b>Quoting Jennybananna:</b>" No we dont. Its the same exact thing. Same dosage. "</blockquote> Okay."
Its right there on their website 68mg. Not varies per person but just 68mg. http://www.nexplanon-usa.com/en/consumer/index.asp
Right from their dosage information:
---- DOSAGE FORMS AND STRENGTHS ---------------------
NEXPLANON consists of a single, radiopaque, rod-shaped implant,
containing 68 mg etonogestrel, pre-loaded in the needle of a
disposable applicator. (3)
Overweight women: NEXPLANON may become less effective in
overweight women over time, especially in the presence of other
factors that decrease etonogestrel concentration
Its just one single dose no matter what you weigh. Im not trying to screw with you but just inform you of the facts.
