Lately i have been SUPER freaking cranky ive been on the implanon for only 4 months ago, i was told bya family member to use St Johns Wart for the really bad mood swings{as i had used before when i was younger} but now I am reading that it will effect the implanon. However I have only found "he said she said" articles, no precent or studies that have been conducted concerning these two drugs. is this just a myth or is it true? and how much of the SJW is enough to effect the birthcontrol?

Yes, it's true. No amount can be considered "safe" for oral contraception.

"This is from the above link:

"Women taking oral contraceptive pills should be counseled to expect breakthrough bleeding and should consider adding a barrier method of contraception when consuming St Johns wort."

And if you want a more complete study, here's one:

I'd like to suggest you discuss taking St John's Wort with your doctor before starting. "Natural" does not necessarily mean "safe" and it has a number of side effects. Yuor doctor may be able to prescribe something more appropriate for your mood swings.

is IMPLANON considered a oral contraception as it is implanted in my arm rather than a pill i take daily?

The concern is cytochrome P-450 isozyme (CYP3A4) as outlined in the attached:

and the concern from the implanon site regarding potential drug interactions:
