  • Demerol HCl
  • Get emergency medical help if you have signs of an allergic reaction to Demerol: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

    Stop using Demerol and call your doctor at once if you have:

    weak or shallow breathing, slow heartbeat;
    severe drowsiness, feeling like you might pass out;
    confusion, mood changes, agitation, hallucinations;
    seizure (convulsions); or
    tremors, muscle movements you cannot control.
    Meperidine is more likely to cause breathing problems in older adults and people who are severely ill, malnourished, or otherwise debilitated.

    Common Demerol side effects may include:

    dizziness, drowsiness;
    nausea, vomiting; or
  • Dosage should be adjusted according to the severity of the pain and the response of the patient. Meperidine is less effective orally than on parenteral administration. The dose of DEMEROL should be proportionately reduced (usually by 25 to 50 percent) when administered concomitantly with phenothiazines and many other tranquilizers since they potentiate the action of DEMEROL.
