Insert gently with your forefinger
With your gloved forefinger, gently guide the pointed or tapered end of the suppository into the rectum. Insert it just past the sphincter muscle โ approximately one inch for adults. Once past the sphincter, no further insertion is needed. The sphincter will naturally hold it in place.
The sphincter is the ring of muscle you can feel at the entrance. Once the suppository passes just beyond it, stop โ you will feel a natural resistance ease and then hold.
