Can i take panadol (acetaminophen) night 4 hours after taking diclogesic suppository?

Doing it 1 time = OK: It is not a good idea to combine them day after day of treatment, but doing it occasionally should not be a problem.

Yes: You can safely take panadol (acetaminophen) 4 hours after diclogesic suppository. Both these medicines belong to a different class. As a matter of fact panadol (acetaminophen) will provide additional pain relief.
