Work differently, However, I how found sodium picosulfate to be stronger. This can be used for colon cleansing prior to colonoscopy prep. Lactulose is an osmotic laxative and tends to cause more bloating and is not quite as effective as evacuating the colon.
Work Differently. Each work differently & are sometimes used together for colonoscopy preps. S. Picosulphate is a stimulant that irritates your colon to contract to remove stool. Lactulose is a non-digestable sugar that pulls water into your colon to remove stool. Only take these under dr supervision. S. Picosulphate can lead to dependence. Both can lead to dehydration & electrolyte imbalance if taken improperly.
If lactulose does not prove effective then is it good to give sodium picosulphte as laxative to an aged person battling constipation for 6 days?
Constipation. If you have been constipated for 6 days you should see your physician. They should be able to steer you in the right direction for a laxative that is right for you. There could also be other complications that need to be checked out such as impaction.
