· Insert the suppositories rectally. Remove the foil wrapper and insert a suppository into the rectum, pointed end first.

Retain the suppository for one to three hours, or longer, if possible to get the maximum benefit from this medication.

· Shake the rectal suspension well before use. Remove the protective cap from the applicator tip. Hold the bottle at the neck to prevent any of the medication from spilling out. Gently insert the tip into the rectum, pointing toward the belly button (umbilicus). Squeeze the bottle steadily to discharge most of the medication. Retain the suspension overnight if possible to get the maximum benefit from this medication.
