It is typically taken orally (swallowed by mouth) but is also used intravenously.^[10][12] Effects begin within one hour and last between eight and twelve hours in adults.^[8][1]

Common side effects may include sleepiness, weakness, poor coordination, difficulty concentrating, and agitation. Clonazepam may also decrease memory formation.^[10] Long-term use may result in tolerance, dependence, and life-threatening withdrawal symptoms if stopped abruptly.^[10][13] Dependence occurs in one-third of people who take benzodiazepines for longer than four weeks.^[9] The risk of suicide increases, particularly in people who are already depressed.^[10][14] Use during pregnancy may result in harm to the fetus.^[10] Clonazepam binds to GABA_A receptors, thus increasing the effect of the chief inhibitory neurotransmitter γ-aminobutyric acid (GABA).^[9]
