Does any of this apply?
Book an appointment
After discharge, arrange recommended blood tests or appointments to check kidney function, bleeding, or persistent stomach symptoms.
Seek earlier review if urination decreases, vomiting continues, swelling develops, or symptoms return.
And for anyone, someone who:
is having side effects from a medicine, or is struggling to take it as prescribed
The article also says
Do not leave an unconscious or severely drowsy person alone.
Place them on their side if they are breathing and it is safe to do so.
Do not give anything by mouth.
Every sign above is quoted from the sofidex article on Fenoprofen calcium overdose. If you are not sure, err upward — it is always reasonable to be checked.
