Some sufferers from constipation find that they get greater relief from salts dissolved in water, or from natural aperient water taken on rising in the morning, and others again find that the best way of opening the bowels is to inject one or two drachms of glycerine into the rectum, or use it as a suppository.
If you feel your body wanting to push the suppository out, try to resist.
While most drugs are taken by mouth (orally) some are given by suppository or by injection.
If motions are hard and difficult to void, try inserting a glycerol suppository to reduce straining.
Gently but firmly push the suppository into the rectum, pointed end first.
