4-6 hours: Diazepam and codeine have additive sedative effects. So to be careful not to get interactions, I would wait 4-6 hours before taking the codeine. You must be careful as they both can make you tipsy , stumble or fall. So to prevent any side effects separate their use by 4-6 hours.

Probably OK now: Any time. Probably you can safely take both at the same time, unless you are also on other sedative or tranquilizing medications. Codeine's sedative effects are very mild. But check with your own doctor if in doubt.
