What Is Apadaz?

Apadaz (benzhydrocodone and acetaminophen tablets) is a combination of a prodrug of the opioid agonist hydrocodone and a non-narcotic pain reliever and fever reducer indicated for the short-term (no more than 14 days) management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.

What Are Side Effects of Apadaz?

Common side effects of Apadaz include:

  • nausea,
  • drowsiness,
  • vomiting,
  • constipation,
  • itching,
  • dizziness, and
  • headache

Dosage for Apadaz

The dose of Apadaz is individualized based on:

  • the severity of pain,
  • patient response,
  • prior analgesic experience, and
  • risk factors for addiction, abuse, and misuse

The initial dose of Apadaz is 1 or 2 tablets every 4 to 6 hours as needed for pain.

What Drugs, Substances, or Supplements Interact with Apadaz?

Apadaz may interact with:

  • macrolide antibiotics,
  • azole antifungals,
  • protease inhibitors,
  • rifampin,
  • carbamazepine,
  • phenytoin,
  • benzodiazepines and other sedatives/hypnotics,
  • anxiolytics,
  • tranquilizers,
  • muscle relaxants,
  • general anesthetics,
  • antipsychotics,
  • other opioids,
  • alcohol,
  • selective serotonin reuptake inhibitors (SSRIs),
  • serotonin and norepinephrine reuptake inhibitors (SNRIs),
  • tricyclic antidepressants (TCAs),
  • triptans,
  • 5-HT3 receptor antagonists,
  • drugs that affect the serotonin neurotransmitter system (e.g., mirtazapine, trazodone, tramadol),
  • monoamine oxidase inhibitors(MAOIs),
  • opioid analgesics,
  • muscle relaxants,
  • diuretics, and
  • anticholinergics

Tell your doctor all medications and supplements you use.

Apadaz During Pregnancy and Breastfeeding

Tell your doctor if you are pregnant or plan to become pregnant before using Apadaz; prolonged use of opioid analgesics during pregnancy can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. The medications in Apadaz pass into breast milk. Consult your doctor before breastfeeding. Withdrawal symptoms may occur if you suddenly stop taking Apadaz.

Apadaz Consumer Information

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

Opioid medicine can slow or stop your breathing, and death may occur. A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.

In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.

Call your doctor at once if you have:

  • chest pain, fast heartbeats, shallow breathing;
  • extreme drowsiness;
  • a light-headed feeling, like you might pass out;
  • confusion; or
  • liver problems--nausea, upper stomach pain, tiredness, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).

Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.

Serious side effects may be more likely in older adults and those who are overweight, malnourished, or debilitated.

Common side effects include:

  • nausea, vomiting, constipation.
  • dizziness, drowsiness;
  • headache; or
  • itching.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of APADAZ was evaluated in six Phase 1 studies in which a total of 200 healthy adult subjects receive at least one oral dose of APADAZ. The most common AEs (>5%) reported across these studies were: nausea (21.5%), somnolence (18.5%), vomiting (13.0%), constipation (12.0%), pruritus (11.5%), dizziness (7.5%), and headache (6.0%).

The following adverse reactions occurred with an incidence of 1% to 5% in single-dose or repeateddose clinical trials of APADAZ.

Gastrointestinal disorder: abdominal distension, abdominal pain, flatulence

General disorders and administration site conditions: asthenia

Nervous system disorders: presyncope, tremor

Respiratory, thoracic and mediastinal disorders: dyspnea

Vascular disorders: hot flush, hypotension

Adverse reactions occurring at less than 1%: the following lists clinically relevant adverse reactions that occurred with an incidence of less than 1% in APADAZ clinical trials.

Eye disorders: eye pruritus

Gastrointestinal disorders: diarrhea, gastroesophageal reflux disease, haematemesis

General disorders and administration site conditions: chest discomfort

Infections and infestations: rhinitis

Nervous system disorders: hypoesthesia, syncope

Psychiatric disorders: agitation, euphoric mood, nightmare

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of hydrocodone.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Serotonin Syndrome

Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs.

Adrenal Insufficiency

Cases of adrenal insufficiency have been reported with opioid use, more oftenfollowing greater than one month of use.

Anaphylaxis

Anaphylaxis has been reported with ingredients contained in APADAZ.

Androgen Deficiency

Cases of androgen deficiency have occurred with chronic use of opioids [see CLINICAL PHARMACOLOGY].
