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 practice.
Based on data from nine Phase 2/3 studies that administered multiple doses (seven placebo-and/or active-controlled, one noncontrolled and one Phase 3 active-controlled safety study) the most common adverse reactions (reported by ≥10% in any tapentadol tablets dose group) were: nausea, dizziness, vomiting and somnolence.
The most common reasons for discontinuation due to adverse reactions in the studies described above (reported by ≥1% in any tapentadol tablets dose group) were dizziness (2.6% vs. 0.5%), nausea (2.3% vs. 0.6%), vomiting (1.4% vs. 0.2%), somnolence (1.3% vs. 0.2%) and headache (0.9% vs. 0.2%) for tapentadol- and placebo-treated patients, respectively.
Seventy-six percent of tapentadol-treated patients from the nine studies experienced adverse events.
Tapentadol tablets were studied in multiple-dose, active- or placebo-controlled studies, or noncontrolled studies (n = 2,178), in single-dose studies (n = 870), in open-label study extension (n = 483) and in Phase 1 studies (n = 597). Of these, 2,034 patients were treated with doses of 50 mg to 100 mg of tapentadol tablets dosed every 4 to 6 hours.
The data described below reflect exposure to tapentadol tablets in 3,161 patients, including 449 exposed for 45 days. Tapentadol tablets were studied primarily in placebo- and active-controlled studies (n = 2,266, and n = 2,944, respectively). The population was 18 to 85 years old (mean age 46 years), 68% were female, 75% white and 67% were postoperative. Most patients received tapentadol tablets doses of 50 mg, 75 mg, or 100 mg every 4 to 6 hours.

The following adverse drug reactions occurred in less than 1% of tapentadol-treated patients in the pooled safety data from nine Phase 2/3 clinical studies:
Cardiac disorders: heart rate increased, heart rate decreased
Eye disorders: visual disturbance
Gastrointestinal disorders: abdominal discomfort, impaired gastric emptying
General disorders and administration site conditions: irritability, edema, drug withdrawal syndrome, feeling drunk
Immune system disorders: hypersensitivity
Investigations: gamma-glutamyltransferase increased, alanine aminotransferase increased, aspartate aminotransferase increased
Musculoskeletal and connective tissue disorders: involuntary muscle contractions, sensation of heaviness
Nervous system disorders: hypoesthesia, paresthesia, disturbance in attention, sedation, dysarthria, depressed level of consciousness, memory impairment, ataxia, presyncope, syncope, coordination abnormal, seizure
Psychiatric disorders: euphoric mood, disorientation, restlessness, agitation, nervousness, thinking abnormal
Renal and urinary disorders: urinary hesitation, pollakiuria
Respiratory, thoracic and mediastinal disorders: oxygen saturation decreased, cough, dyspnea, respiratory depression
Skin and subcutaneous tissue disorders: urticaria
Vascular disorders: blood pressure decreased
In the pooled safety data, the overall incidence of adverse reactions increased with increased dose of tapentadol tablets, as did the percentage of patients with adverse reactions of nausea, dizziness, vomiting, somnolence, and pruritus.
