Administration route: Administration route means the way a medicine is taken, such as by mouth, under the tongue, or by inhalation through an approved vaporiser. Different routes affect how fast the medicine starts, how long effects last and how predictable dosing feels.
Patients often need this language to understand instructions, onset time and safety advice.
NICE expects discussion of how to take the medicine and how long it may take to work.
Route changes can alter impairment risk, onset and side-effect pattern. Patients should not swap routes without clinician advice.
