# How this medication should be used
Hydromorphone comes as a tablet and liquid to take by mouth. It also comes as a rectal suppository. The oral forms usually are taken every 4-6 hours as needed. The suppository usually is used every 6-8 hours as needed. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.
Shake the liquid well before measuring a dose. Take hydromorphone exactly as directed. Hydromorphone can be habit-forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to.

- Remove the wrapper.
- Dip the tip of the suppository in water.
- Lie down on your left side and raise your right knee to your chest. (A left-handed person should lie on the right side and raise the left knee.)
- Using your finger, insert the suppository into the rectum, about 1/2 to 1 inch for infants and children and about 1 inch for an adult.
- Hold it in place with your finger for a few moments.
- Stand up after about 15 minutes. Wash your hands thoroughly and resume normal activities.
