Why this happens
These medicines work in different ways and are processed by different pathways in the body. Paracetamol is primarily processed by the liver to relieve pain and fever, while cetirizine is an antihistamine that is mostly cleared by the kidneys. They do not interfere with how the other is absorbed or removed from the system.
What you should do
You can take paracetamol and cetirizine at the same time if needed. Always follow the dosage instructions on the packet for each individual medicine. If you feel unusually sleepy, avoid driving or operating machinery until you feel more alert.

Important precautions
Liver disease or heavy alcohol consumption
You are at a much higher risk of serious liver damage from paracetamol; do not exceed the recommended dose and consult your doctor before use.
Epilepsy or history of seizures
This medication may increase the risk of having a seizure.
Concurrent use of other cold, flu, or pain remedies
Many other medicines contain paracetamol; taking them together can lead to a fatal overdose. Always check labels for paracetamol or APAP.
Food and drink warnings
Alcool
While cetirizine is a non-drowsy antihistamine, alcohol can increase the risk of feeling sleepy or dizzy. It is best to avoid drinking alcohol while taking this medicine to see how it affects you first.
