- Brief summaryThe prevalence of sleep disorders increases with age. Sleep disorders have serious health implications and may be related to serious underlying diseases. Many older people use hypnotics like benzodiazepines, although these medications have side effects and often lead to habituation. If, however, there would be an easy treatment for sleep problems, many patients could benefit. Some people use acetaminophen as a sleeping pill and are convinced this works. Few is known about the effect of acetaminophen at sleep. Acetaminophen might be a simple and cheap treatment for sleep disorders with low side effects. The ASLEEP-study could contribute to our knowledge about treatment of sleep problems.
Therefore, we want to conduct a double-blind, randomized, placebo-controlled trial to investigate if acetaminophen is effective in treating self-reported sleep problems in a geriatric population.
