Of course, you can! They are two entirely different things.
Antipyretics (like Paracetamol) or anti-inflammatory drugs (like Ibuprofen), neutralise the agents released from cells casing fever, swelling, pain etc. They do not kill bacteria, or viruses for that matter. Paracetamol is metabolised (broken down) in liver, while Ibuprofen is cleared by the kidneys. For this reason, they can be given together, if timing co-insides.
Antibiotics are prescribed to combat harmful bacteria and kill them. They may take 24-48 hours to ‘kick-in’ and kill enough bacteria to control the inflammatory process, causing raised body temperature etc. Till that time or even afterwards, continue using Paracetamol / Ibuprofen, as advised.
