2.1 Important Dosage and Administration Instructions

Ensure accuracy when prescribing, dispensing, and administrating DEMEROL Oral Solution to avoid dosing errors due to confusion between mg and mL, and with other Meperidine Hydrochloride Oral Solutions of different concentrations, which could result in accidental overdose and death. Ensure the proper dose is communicated and dispensed. When writing prescriptions, include both the total dose in mg and the total dose in volume.

Do not use household teaspoons or tablespoons to measure DEMEROL Oral Solution, as using a tablespoon instead of a teaspoon could lead to overdosage.

Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)].

Dilute each dose of DEMEROL oral solution in one-half glass of water because the undiluted solution may exert a slight topical anesthetic effect on mucous membranes.

Initiate the dosing regimen for each patient individually; taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.2)].

Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with DEMEROL Tablets or Oral Solution and adjust the dosage accordingly [see Warnings and Precautions (5.4)].

2.2 Initial Dosage


Initiate treatment with DEMEROL Tablets or Oral Solution in a dosing range of 50 mg to 150 mg orally, every 3 or 4 hours as needed for pain.

Pediatric Patients

Initiate treatment with DEMEROL Tablets or Oral Solution in a dosing range of 1.1 mg/kg to 1.8 mg/kg orally, up to the adult dose, every 3 or 4 hours as necessary.

2.3 Dosage Modification with Concomitant Use with Phenothiazines

The dose of DEMEROL Tablets or Oral Solution should be reduced by 25 to 50% when administered concomitantly with phenothiazines and other tranquilizers.

2.4 Titration and Maintenance of Therapy

Individually titrate DEMEROL Tablets and Oral Solution to a dose that provides adequate analgesia and minimizes adverse reactions. If adequate pain management cannot be achieved with a total daily dosage of 600 mg or less, discontinue treatment with DEMEROL Tablets or Oral Solution by tapering the dose and select an alternate analgesic.

Continually reevaluate patients receiving DEMEROL Tablets or Oral Solution to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse [see Warnings and Precautions (5.2)]. Frequent communication is important among the prescriber, other members of the healthcare team, the patient, and the caregiver/family during periods of changing analgesic requirements, including initial titration.

If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the DEMEROL Tablets or Oral Solution dosage. If unacceptable opioid-related adverse reactions are observed, consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.

2.5 Discontinuation of DEMEROL Tablets or Oral Solution

When a patient who has been taking DEMEROL Tablets or Oral Solution regularly and may be physically dependent no longer requires therapy with DEMEROL Tablets or Oral Solution, taper the dose gradually, by 25% to 50% every 2 to 4 days, while monitoring carefully for signs and symptoms of withdrawal. If the patient develops these signs or symptoms, raise the dose to the previous level and taper more slowly, either by increasing the interval between decreases, decreasing the amount of change in dose, or both. Do not abruptly discontinue DEMEROL Tablets or Oral Solution in a physically-dependent patient. [see Warnings and Precautions (5.15), Drug Abuse and Dependence (9)].
