how long does it take for an enema to work

An enema typically starts working within about 5 minutes and can take up to an hour to fully take effect. Most people feel the urge to have a bowel movement within 1 to 5 minutes after administration, but they should remain near a toilet and set aside up to an hour to ensure it has worked completely. Different types of enemas vary in speed—saline enemas often work within 5 to 15 minutes, bisacodyl enemas in 15 to 60 minutes, and mineral oil or soap suds enemas may take longer, up to an hour. It is recommended to lie on your side after giving yourself an enema and hold the fluid in for as long as possible, usually no more than 5 minutes before the urge starts. If no bowel movement occurs after an hour, medical advice should be sought.
