i recently had shoulder reconstruction (5 weeks) including bicep tendoesis. i was given 5mg of endone tablets on discharge from hospital to take each 4-6 hours and due to being a small woman (54 kilo) i was only able to take 1 tablet rather than two for pain. Yesterday i took two by mistake (was only meaning to take panadol but wrong packet was grabbed) following a sore session and pain after physio. was sick and vomitted 5 times, very sleepy and generally very unwell. this morning still feel very off im stomach, how long does this drug stay in the system?
