yes please . I believe the fentanyl patch that I have been using for ms issues &now post - op problems has caused severe hair loss. I am a woman who s hair has always been fine, thin, & board straight, but there was enough to be pretty. It had been halfway down my back and seemed completely normal. Now that I have been titrated up to 100mcg s over a significant period of time I started to notice that my hair was coming out in very unusually large amounts; like after shampooing, daily brushing (which has always actually been combing with a wide tooth comb so I wouldn t rip it out), even taking out 1 of my gazillion fabric scrunchies there would be a pile of hair tangled in it which had never ever happened before. It has broken off everywhere almost totally. does anyone know if this keeps going or if it slows or even stops as your system adjusts to the med? I m going to have to get off it which is really unfortunate for me because it actually allows me to function on a daily basis but the idea of losing the rest of my hair is terrifying! Any info.,help, or suggestions would be much appreciated.
