Newly-weds receiving order for sedatives (8)

I believe the answer is:

bromides

'sedatives' is the definition.
(bromide is a kind of sedative)

'newly-weds receiving order' is the wordplay.
'newly-weds' becomes 'brides'.
'receiving' means one lot of letters goes inside another.
'order' becomes 'om' (order of merit).
'brides' placed around 'om' is 'BROMIDES'.

'for' acts as a link.

(Another definition for bromides that I've seen is " boring types".)

I've seen this clue in The Guardian.
