From 3 days I take Gripex Night 500mg paracetamol x 4 tablets daily every 6 hours. Today instead of the fourth tablet I took Vicks AntiGrip Max 1000mg paracetamol - I was so tired and I want to sleep, can it be a side effect of the drug or paracetamol poisoning?

The described symptoms may result from the action of the active substances contained in Vicks Antigrip Max (phenylephrine and chlorphenamine) - drowsiness, coordination disorders or weakness are common side effects of this preparation. The doses of paracetamol taken are the maximum that can be taken during the day and the dosage should be reduced in the following days, which you can read about in the link below: https://www.gdziepolek.pl/opinie-i-pytania/13908/paramax-ile-paracetamolu-w-ciagu-doby-moze-zazyc-osoba-dorosla Below I leave information on the symptoms of paracetamol poisoning: "Overdose symptoms associated with paracetamol: nausea, vomiting, loss of appetite, yellow discoloration of the skin and eyes (jaundice), abdominal pain, diarrhea, excessive sweating. Acute hepatic failure and hepatic necrosis may occur and may be fatal."
