Hello,
Thank you for posting your question to HCM,
From what you are describing it doesn't look like a
allergic reaction from the medicine, and the medicine itself is not from those who give a allergic reaction. You should have used it before, because its a very used medicine.
The most possible cause of the itchiness may be because you have lost fluids during the time you have been sick, from the
fever maybe, or secretions and the sickness itself. The
dry skin becomes itchy.
Make sure to drink plenty of fluids in the days to come, and apply moisturizing creams if possible.
Panadol is a medicine that damages the
liver if its used in excess, so try to not use it more then 8 tablets/day. If possible stop using it at all for some time.
If worse, or not better, contact with your local doctor so he does an evaluation of the skin and your liver function also.
Hope the information was helpful.
Let me know if you have further queries. I would be happy to answer.
Take care,
Dr. Papaqako
