Is any of this happening now?
Call 911
Call emergency services or go to an emergency department if you have possible liver injury together with:
Confusion, unusual behaviour, or difficulty staying awake
Vomiting blood, black stools, or heavy unexplained bleeding
A suspected overdose, even if you currently feel well
Rapidly worsening jaundice with severe weakness or repeated vomiting
For mild symptoms or an unexpected abnormal liver test without emergency signs, promptly contact the clinician who prescribed the medicine.
Do not restart a stopped product or make major medication changes without advice unless emergency services tell you to do so.
And for anyone, someone who:
is bleeding heavily and it will not stop with firm pressure
you believe has taken an overdose or swallowed something poisonous
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy

Is any of this happening?
Be seen today
Seek urgent same-day medical advice for new yellowing of the eyes or skin, dark urine with pale stools, persistent vomiting, or significant pain in the upper right abdomen.
A widespread rash, fever, facial swelling, breathing difficulty, or mouth sores after starting a medicine also needs urgent assessment.
These can indicate a serious whole-body drug reaction.
