Respiratory depression may occur, especially in the presence of alcohol, which enhances the depressive side effect of diazepam, in addition opioid drugs also enhance the cardiac and respiratory depressive effect of diazepam.
Hypotension may occur. This may be significant if the patient has to be moved from a horizontal position to allow for extrication from the address. Caution should therefore be exercised and consideration given to either removing the patient flat or, if fitting has stopped and it is considered safe, allowing a 10 minute recovery period prior to removal.
Drowsiness and light-headedness, confusion and unsteadiness.
Occasionally amnesia may occur.
