Thanks for using Healthcaremagic,
You are taking penicillin,Ibuprofen
, and you have allergic reaction
that is urticaria
it can occur due to penicillin or any other drug.
You should stop all the drugs and some anti allergy
medicine like cetirizine
may help to reduce discomfort.
If Itching is more and rash
is troublesome than visit to emergency room (ER) is warranted.
Out of these paracetamol is least likely to be culprit, you should visit a physician and take appropriate therapy in case of allergy to penicillin safe antibiotics from macrolide
group like Erythromycin
may be used.
Hope this helps.
