Palladone Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Palladone (hydromorphone HCl) extended-release used to manage pain in opioid-tolerant patients severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Common side effects include constipation, nausea, vomiting, nervousness, dizziness, drowsiness, itching, dry mouth, sweating, weakness, and headache.
Dose of Palladone is individualized for each patient, taking into account the patient's prior analgesic treatment experience and risk factors for addiction, abuse, and misuse. Palladone may interact with alcohol, sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, pentazocine, nalbuphine, butorphanol, buprenorphine, monoamine oxidase inhibitors (MAOIs), and anticholinergics. Tell your doctor all medications and supplements you use. Palladone is not recommended for use during pregnancy. It may harm a fetus. If used during pregnancy it can cause withdrawal symptoms in a newborn. This drug passes into breast milk and may harm a nursing baby. Breastfeeding is not recommended while taking Palladone. Withdrawal symptoms may occur if you suddenly stop taking this medication.
Our Palladone (hydromorphone HCl) extended-release Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Clinical Trial Experience
The safety of PALLADONE was evaluated in double-blind clinical trials involving 612 patients with moderate to severe pain. An open-label extension study involving 143 patients with cancer pain was conducted to evaluate the safety of PALLADONE when used for longer periods of time in higher doses than in the controlled trials. Patients were treated with doses averaging 40 to 50 mg of PALLADONE per day (ranging between 12 and 500 mg/day) for several months (range 1 to ≥ 52 weeks).
Serious adverse reactions which may be associated with PALLADONE therapy in clinical use are similar to those of other opioid analgesics, including respiratory depression, apnea, respiratory arrest, and to a lesser degree, circulatory depression, hypotension, shock or cardiac arrest [see OVERDOSAGE].
Adverse Events Reported in Controlled Trials
Table 2 lists treatment emergent signs and symptoms that were reported in at least 2% of patients in the placebo-controlled trials for which the rate of occurrence was greater for those treated with PALLADONE 12 mg capsules than those treated with placebo.
Table 2: Adverse Events Reported in the
Placebo-Controlled Clinical Trials with Incidence ≥ 2% in Patients Receiving
PALLADONE Capsules for Nonmalignant Pain
|Body System / Adverse Event (COSTART Terminology)||Placebo*
|Total percentage of patients with AEs||35.10%||49.50%|
|Body as a Whole||15.70%||18.40%|
|* Average exposure was 21 days for PALLADONE and 15 days for placebo.|
Adverse Events Observed in Clinical Trials
PALLADONE has been administered to 785 individuals during completed clinical trials. The conditions and duration of exposure to PALLADONE varied greatly, and included open-label and double-blind studies, uncontrolled and controlled studies, inpatient and outpatient studies, fixed dose and titration studies. Untoward events associated with this exposure were recorded by clinical investigators using terminology of their own choosing.
These categories are used in the listing below. The frequencies represent the proportion of 785 patients from these trials who experienced that event while receiving PALLADONE. All adverse events included in this tabulation occurred in at least one patient. Events are classified by body system and listed using the following definitions: frequent adverse events -those occurring in at least 1/100 patients; adverse events occurring with an incidence less than 1% are considered infrequent. These adverse events are not necessarily related to PALLADONE treatment and in most cases were observed at a similar frequency in placebo-treated patients in the controlled studies.
