Sublingual administration of pills bypasses the liver I think but makes a second pass trough the liver. Supposedly, it doesnt pass through the liver twice that way, but once, after it hits the blood stream. It is easier on the liver, in theory, but I wouldnt do that with AA pils if you have em, they wind up being perdy nasty I think, not sure. My spiro tastes like mint, but I'm not 100% sure if it can be sublingually taken. As for my Estro, its a once a week injection, so I cannot comment on it sublingually, but it may be safer on the liver? Not much help, but hope it helps a little. I would consult my dr. or endo before I changed the way I take my meds, though.
