Popular sleep aids before surgery could prevent painkiller dependence later
A review of 16 studies suggests that taking melatonin or zolpidem (Ambien) before surgery may be linked to less anxiety and pain afterwards, as well as lower opioid use in some patients. The findings matter because they point to sleep before surgery as a possible factor in recovery and pain management.
The studies covered more than 1,100 patients who had various procedures between 2000 and 2025. Melatonin was associated with a greater than 30% reduction in opioid use among some abdominal surgery patients; zolpidem was linked to reduced opioid use after colorectal surgery. The review summarised existing research rather than testing a treatment, so its authors said further research is needed and did not make clinical recommendations.
In short
- Better sleep before surgery may be linked to less pain afterwards.
- Some studies found lower opioid use with melatonin or zolpidem.
- The review does not establish treatment advice.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The review suggests that improving sleep before surgery could ease anxiety and pain, and may reduce opioid use for some patients. If further research confirms the link, sleep aids could become a useful part of recovery planning and help limit exposure to medicines that carry a risk of dependence.
The case against
The evidence comes from a review of varied studies, not a trial designed to show that sleep aids prevent opioid dependence, and the reported benefits applied to some patient groups. Melatonin and zolpidem also have potential downsides, so presenting them as preventive treatment before stronger evidence is available could encourage use without a clear clinical benefit.
Explained simply
After an operation, patients may be given opioid painkillers, which can cause side effects and carry a risk of dependence. Pain and anxiety can also affect recovery, while poor sleep is common before and after surgery.
Melatonin is a hormone that helps regulate sleep; zolpidem, sold under the brand name Ambien, is a prescription medicine for insomnia. Researchers have examined whether these sleep aids taken before surgery are linked to patients’ pain, anxiety and opioid use afterwards.
A review brings together results from earlier studies, which can show patterns but cannot by themselves establish that a medicine caused them. Decisions about medicines around surgery are made by patients and their clinical teams based on individual circumstances.
