I have a friend who has been taking Ativan (lorazepam) as prescribed, for about 6 years. In that time her conversations with me reveal an increasing paranoia--about people watching or overhearing her (for example, although she owns her own home, she will whisper in conversation with me on the telephone, even though she lives alone). This problem has gotten worse over time (and her short-term memory and ability to pull her thoughts together, as well).
Can this be related to the lorazepam?
