This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS 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.
In Phase 3 clinical trials, a total of 397 subjects received Veregen three times per day topical application for the treatment of external genital and perianal warts for up to 16 weeks.
Serious local adverse events of pain and inflammation were reported in two subjects (0.5%), both women.
In clinical trials, the incidence of patients with local adverse events leading to discontinuation or dose interruption (reduction) was 5% (19/397).
These included the following events: application site reactions (local pain, erythema, vesicles, skin erosion/ulceration), phimosis, inguinal lymphadenitis, urethral meatal stenosis, dysuria, genital herpes simplex, vulvitis, hypersensitivity, pruritus, pyodermitis, skin ulcer, erosions in the urethral meatus, and superinfection of warts and ulcers.
Local and regional reactions (including adenopathy) occurring at >1% in the treated groups are presented in Table

Severe reactions occurred in 37% (71/192) of women and in 24% (49/205) of men.
The percentage of subjects with at least one severe, related adverse event was 26% (86/328) for subjects with genital warts only, 42% (19/45) in subjects with both genital and perianal warts and 48% (11/23) of subjects with perianal warts only.
Phimosis occurred in 3% of uncircumcised male subjects (5/174) treated with Veregen and in 1% (1/99) in vehicle.
5 WARNINGS AND PRECAUTIONS Veregen has not been evaluated for the treatment of urethral, intra-vaginal, cervical, rectal, or intra-anal human papilloma viral disease and should not be used for the treatment of these conditions.
Use of Veregen on open wounds should be avoided.
Patients should be advised to avoid exposure of the genital and perianal area to sun/UV-light as Veregen has not been tested under these circumstances.
• Veregen should not be used to treat urethral, intra-vaginal, cervical, rectal, or intra-anal human papilloma viral disease (5) .
