Mention me going west, inducing sickness (6)
I believe the answer is:
Here is my best explanation:
'inducing sickness' is the definition.
(I've seen this before)
'mention me going west' is the wordplay.
'mention' becomes 'cite' (synonyms).
'going west' shows that the letters should be reversed in order.
'citeme' backwards is 'EMETIC'.
