"i have been on duragesic for past 2 years. i&#039;m on a dose of 150mcg every 72 hours. i have sickle cell anemia and have intolerable back pain on a daily basis. these patches work wonders for my pain but i am a girl who loves to take baths. just letting you know that you should not take really hot or really long baths while on the patch. i did and i thought i was going to die. my heart began to race and i had trouble breathing. after i struggled to get out of bathtub my husband snatched the patches off, scrubed the area they were at and i started feeling better in about 10-15 minutes. i love it for the pain but hate it for my baths."
