Denavir FDA Prescribing Information: Side Effects
(Adverse Reactions)
SIDE EFFECTS
In two double-blind, placebo-controlled trials, 1516 patients were treated with Denavir (penciclovir cream) and 1541 with placebo. The most frequently reported adverse event was headache, which occurred in 5.3% of the patients treated with Denavir (penciclovir) and 5.8% of the placebo-treated patients. The rates of reported local adverse reactions are shown in Table 2 below. One or more local adverse reactions were reported by 2.7% of the patients treated with Denavir (penciclovir) and 3.9% of placebo-treated patients.
Table 2--Local Adverse Reactions Reported in Phase III Trials
| Penciclovir n= 1516 % |
Placebo n=1541 % |
|
| Application site reaction | 1.3 | 1.8 |
| Hypesthesia/Local anesthesia | 0.9 | 1.4 |
| Taste perversion | 0.2 | 0.3 |
| Pruritus | 0.0 | 0.3 |
| Pain | 0.0 | 0.1 |
| Rash (erythematous) | 0.1 | 0.1 |
| Allergic reaction | 0.0 | 0.1 |
Two studies, enrolling 108 healthy subjects, were conducted to evaluate the dermal tolerance of 5% penciclovir cream (a 5-fold higher concentration than the commercial formulation) compared to vehicle using repeated occluded patch testing methodology. The 5% penciclovir cream induced mild erythema in approximately one-half of the subjects exposed, an irritancy profile similar to the vehicle control in terms of severity and proportion of subjects with a response. No evidence of sensitization was observed.
