Hi. thanks for asking in Healthcare Magic.
You have taken roughly 4 gm of Paracetamol
and 2.4 gm of Ibuprofen and it is a toxic dose for your age as they are taken together. The early symptoms are nausea, vomiting and abdominal pain
. Both drugs produce severe gastritis. The severe left side pain could be due to gastritis. You should see your treating Dr immediately to prevent further complications.
by Paracetamol is delayed and occurs after 12 to 18 hours. If liver is affected then it will present as jaundice after 2 days. N-Acetyl Cysteine is the specific treatment for Paracetamol induced liver damage. Since the toxic effects of Paracetamol become evident only after 12 hours, you should seek medical help
as soon as possible.
I hope this is useful to you.
