Demerol
Demerol ® Also known as Pethidine or meperidine, is a combination of acetaminophen (Tylenol) and propoxyphene designed to relieve mild to moderate pain. Propoxyphene binds to the pain receptors in the brain so that the sensation of pain is reduced. Acetaminophen halts the production of prostaglandins which otherwise cause pain.

Demerol is classified as a Schedule II controlled substance in the U.S.

Demerol ® is an opiate taken as a pill, liquid or patch formulated to be taken every 4 hours by mouth.

Dependency is as much an issue as with other opioids, but there is an added danger to those with kidney or liver disease.

Withdrawal is a key indicator that a physical addiction to Demerol is present. Symptoms of withdrawal are much the same for all narcotic pain medications.

They include:
diarrhea
stomach cramps
muscle and bone pain
anxiety
agitation
runny nose
nausea
insomnia
magnified flu-like symptoms
tremors and restlessness.

If these symptoms appear when you discontinue use and disappear when you take it again, you are addicted to Demerol. Other signs include a preoccupation or obsession with obtaining and consuming the drug. If you feel you are unable to control your use of Demerol, you do have a problem that may require medically-sponsored help.
