Vantrela ER (hydrocodone bitartrate) extended-release tablets are an opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Vantrela ER is available in generic form. Common side effects of Vantrela ER include:

  • nausea,
  • constipation,
  • headache,
  • drowsiness,
  • vomiting,
  • dizziness,
  • itching,
  • fatigue,
  • dry mouth,
  • diarrhea,
  • insomnia, and
  • anxiety.

The dosing of Vantrela ER is individualized based on the severity of pain, patient response, prior analgesic experience, and risk factors for addiction, abuse, and misuse. For opioid-naïve and opioid non-tolerant patients, the initial dose of Vantrela ER is 15 mg tablets orally every 12 hours. Vantrela ER 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), butorphanol, nalbuphine, pentazocine, buprenorphine, muscle relaxants, diuretics, and anticholinergics. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Vantrela ER. Prolonged use of Vantrela ER during pregnancy can result in withdrawal signs in newborns. Vantrela ER passes into breast milk and may cause unwanted effects on a nursing baby. Breastfeeding while using Vantrela ER is not recommended. Withdrawal symptoms may occur if you suddenly stop taking Vantrela ER.

The following serious adverse reactions are discussed elsewhere in the labeling:

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the 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 clinical practice.

The safety of VANTRELA ER was evaluated in 1176 patients who were enrolled in two doubleblind clinical trials and in two open-label studies. The adverse drug reactions (reported in ≥ 2% of patients) by preferred term during the titration period and/or the post-titration treatment period of the two double-blind studies by treatment group are shown on Table 2.

Table 2: Adverse Drug Reactions (Reported in ≥ 2% of Patients) by Preferred Term and Treatment Group During the Titration Period and/or Double-Blind Post-Titration Treatment Period in Studies 1 and 2

MedDRA 16.0 preferred term Titration Period* Double-Blind Treatment Period
n (%)

Nausea 168 (17) 23 (7) 39 (12)
Constipation 152 (15) 15 (5) 46 (14)
Headache 85 (8) 16 (5) 21 (6)
Somnolence 81 (8) 3 ( < 1) 9 (3)

Diarrhea 22 (2) 10 (3) 12 (4)
Insomnia 18 (2) 9 (3) 4 (1)
Anxiety 7 ( < 1) 5(2) 13 (4)
Patients are counted only once in each preferred term category.
* Titration Period includes all patients who started the open-label titration for the 2 double-blind studies (Studies 1 and 2), regardless if they entered the Double-Blind Treatment Period or not.

The common ( ≥ 1% to < 10%) adverse drug reactions reported at least once by patients treated with VANTRELA ER in all four Phase 3 clinical trials (N=1176) and not represented in Table 2 were:

Ear and Labyrinth Disorders: Tinnitus

Nervous System Disorders: Lethargy; Sedation; Tremor

Psychiatric Disorders: Depression

Respiratory, Thoracic, and Mediastinal Disorders: Cough

Skin and Subcutaneous Tissue Disorders: Hyperhidrosis

Vascular Disorders: Hot flush

Other important rare ( < 1% ) adverse drug reactions reported at least once by patients treated with VANTRELA ER in all Phase 3 clinical trials were:

Gastrointestinal Disorders: Intestinal obstruction, Pancreatitis

Immune System Disorders: Drug hypersensitivity

Respiratory, Thoracic, and Mediastinal Disorders: Respiratory depression

Skin and Subcutaneous Tissue Disorders: Erythema

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 often following greater than one month of use.

Anaphylaxis: Anaphylaxis has been reported with ingredients contained in VANTRELA ER.

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