Apadaz Dosage

Dosage form: tablet

Medically reviewed by Last updated on May 17, 2019.

Important Dosage and Administration Instructions

  • Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. The total dosage of APADAZ and any concomitant acetaminophen-containing products should not exceed 4000 mg of acetaminophen in a 24-hour period.
  • 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 (5.1)].
  • Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with APADAZ and adjust the dosage accordingly [see Warnings and Precautions (5.3)].

Initial Dosage

Use of APADAZ as the First Opioid Analgesic
Initiate treatment with APADAZ at 1 to 2 tablets every 4 to 6 hours as needed for pain. Dosage should not exceed 12 tablets in a 24-hour period.

Conversion from Other Opioids to APADAZ

There is inter-patient variability in the potency of opioid drugs and opioid formulations. Therefore, a conservative approach is advised when determining the total daily dosage of APADAZ. It is safer to underestimate a patients 24-hour APADAZ dosage than to overestimate the 24-hour APADAZ dosage and manage an adverse reaction due to overdose.

Conversion from Hydrocodone Bitartrate/Acetaminophen to APADAZ
Patients can be converted from immediate-release hydrocodone bitartrate/acetaminophen to a dosing regimen of APADAZ as shown in Table 1.

Titration and Maintenance of Therapy

Individually titrate APADAZ to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving APADAZ 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 (5.1)]. 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 APADAZ 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.

Total dosage of APADAZ and any concomitant acetaminophen-containing products should not exceed 4000 mg of acetaminophen in a 24-hour period.

Discontinuation of APADAZ

When a patient who has been taking APADAZ regularly and may be physically dependent no longer requires therapy with APADAZ, 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 APADAZ in a physically dependent patient [see Warnings and Precautions (5.16), Drug Abuse and Dependence (9.3)].
