Hi. While researching the half life of Pregabalin (very short) I came across this recent important report:
"MHRA/CHM advice: Pregabalin (Lyrica®): reports of severe respiratory depression (February 2021)
A European review of pregabalin safety data identified worldwide reports of severe respiratory depression, in some cases without concomitant opioid treatment. Healthcare professionals are advised to consider whether adjustments in dose or dosing regimen are necessary in patients at higher risk of respiratory depression, including those: with compromised respiratory function, respiratory or neurological disease, or renal impairment; taking other CNS depressants (including opioid-containing medicines);
aged older than 65 years.
Patients should be advised to seek medical help if they experience any trouble breathing or shallow breathing; a noticeable change in breathing may be associated with sleepiness.”
