Kmy, should be ok to take panadol even on aspirin as they are on different types of medicines, so no fear overdose or anything. Just keep within safe limits of panadol, max 8 tab a day, at least 4-6h in between every dose. I'm also on aspirin but I have taken panadol for headache also. But just take plain panadol, not panadol flu as panadol flu contains a medicine that is not so good for blood flow to womb.
