Qutenza (Capsaicin) - Side Effects and Adverse Reactions



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

Application-Associated Pain [see Warnings and Precautions (5.4)]

Increase in Blood Pressure [see Warnings and Precautions (5.5)]

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 other drugs and may not reflect the rates observed in clinical practice.

Across all controlled and uncontrolled trials, more than 1,600 patients have received Qutenza. A total of 394 patients received more than one treatment application and 274 patients were followed for 48 weeks or longer.

In controlled clinical studies, 98% of patients completed ≥ 90% of the intended patch application duration. Among patients treated with Qutenza, 1% discontinued prematurely due to an adverse event.

Controlled Clinical Studies

Common Adverse Reactions

Adverse reactions occurring in ≥ 5% of patients in the Qutenza group and at an incidence greater than in the control group were application site erythema, application site pain, application site pruritus and application site papules.

Table 1 summarizes all adverse reactions, regardless of causality, occurring in ≥ 1% of patients with postherpetic neuralgia in the Qutenza group for which the incidence was greater than in the control group. The majority of application site reactions were transient and self-limited. Transient increases in pain were commonly observed on the day of treatment in patients treated with Qutenza. Pain increases occurring during patch application usually began to resolve after patch removal. On average, pain scores returned to baseline by the end of the treatment day and then remained at or below baseline levels. A majority of Qutenza-treated patients in clinical studies had adverse reactions with a maximum intensity of "mild" or "moderate".
