Yes i quite agree you have to have your own system for checking.
My major ones have been:
Loprazolam and Lorazepam.
Tramadol and Trazodone.
Co-codamol and Co-dydramol.
Salbutamol MDI and Salbutamol Breath-Actuated.
and
Cephadine 500 instead of 250 (I don't know why on this one but the patient will get better quicker!!)

Remember we are all human and everybody makes mistakes it is how we respond to the patient after the mistake has been made as to whether they take it furthur.
