When sleep medicines are used every night for more than a few weeks, they may lose their effectiveness or cause dependence. Call your doctor if your insomnia worsens or does not improve within 7 to 10 days of beginning treatment. This may mean that there is another condition causing your sleep problems. Tell your doctor if you experience abnormal thinking, mood problems, behavior changes, anxiety, or memory loss while taking this medication.
