Laxatives-Types,Uses And Dosage


Laxatives-Types,Uses And Dosage.

Laxatives are medicines that are used to stop or treat hard stools or constipation (enhancing or stimulating bowel movement).

Laxatives are used too far; they should be used only ocasionally to help soften hard, painful stools (constipation). Never give laxatives to anyone who has diarrhea or gut pain or who is dehydrated.

Do not give laxatives to small children below or under 2 years old.

Generally, the best stool softeners are foods high in roughage or fiber like bran or cassava. Drinking a lot of liquid, at least 8 glasses of water a day and eating lots of fruit also help.

The following below are types of laxatives, their uses and dosage :

This is a laxative, it is sometimes taken by persons with piles (hemorrhoids) who have hard, painful stools. However, it does not really soften the stools but merely greases them. Foods high in fiber like bran and cassava are far better.

Dosage of mineral oil as a laxative

  • Adults and children between 12 years old and above : Give 1 to 3 teaspoons by mouth at least 1 hour after the evening meal.

Do not take with meals because the oil will rob some of the vitamins from the food.

CAUTION : Do not give to children under 12 years old, women who are pregnant or breast feeding, to persons who cannot get out of bed, or to persons who have trouble swallowing.



These are bullet shaped pills that are pushed into the anus. They stimulate the bowel and cause it to push out the stool.

Dosage for glycerine suppositories

  • Adults and children over 12 years old : Push 1 suppository well up the anus and let it stay there for 15 to 30 minutes ( It helps to lie down). The longer you let the suppository stay inside the anus, the better it will work.
