Demerol

You can build up tolerance to, and both mental and physical dependence on, Demerol if you take it repeatedly. Since it is possible that you could become addicted to Demerol, do not use it for any purpose other than what your doctor has prescribed it for. If you have ever had a problem with drug abuse, consult with your doctor before taking this drug.

Do not abruptly stop using Demerol, especially if you have been taking it for a while. Your doctor will have you gradually taper off this medication to reduce the risk of withdrawal symptoms, including restlessness, irritability, anxiety, insomnia, rapid heartbeat or breathing, increased blood pressure, or flu-like symptoms.

Use Demerol with caution if you have any of the following: a severe liver or kidney disorder, sickle cell anemia, hypothyroidism (underactive thyroid gland), adrenal gland dysfunction or tumor, an enlarged prostate, a urethral stricture (narrowing of the tube leading from the bladder), a severe abdominal condition, an irregular heartbeat, a history of convulsions, or a history of alcoholism (including alcohol withdrawal marked by delirium tremens).

Be very careful taking this drug if you are having a severe asthma attack, if you have frequently recurring lung disease, if you are unable to inhale or exhale extra air when needed, or if you have any pre-existing breathing difficulties.

Use Demerol with caution if you have suffered any type of head injury. This medication may cause unusually slow or troubled breathing and may increase the pressure from fluid surrounding the brain and spinal cord. Demerol should be used by people with a head injury only if the doctor considers it absolutely necessary.

Demerol may make you feel light-headed or dizzy when you get up from lying down.

Before having surgery, make sure the doctor knows you are taking Demerol. Combining Demerol with a general anesthetic could cause serious side effects.

Possible food and drug interactions when taking Demerol

It's very important not to combine Demerol with any sleep medications or tranquilizers, since this combination could cause serious injury or death.
