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.
Patient Counseling Information
See FDA-approved patient labeling (PATIENT INFORMATION)
Patients using Veregen® should receive the following information and instructions:
- This medication is only to be used as directed by a physician. It is for external use only. Eye contact should be avoided as well as application into the vagina or anus.
- It is not necessary to wash off Veregen® prior to the next application. When the treatment area is washed or a bath is taken, the ointment should be applied afterwards.
- It is common for patients to experience local skin reactions such as erythema, erosion, edema, itching, and burning at the site of application. Severe skin reactions can occur and should be promptly reported to the healthcare provider. Should severe local skin reaction occur, the ointment should be removed by washing the treatment area with mild soap and water, and further doses withheld.
- Sexual (genital, anal or oral) contact should be avoided while the ointment is on the skin, or the ointment should be washed off prior to these activities. Veregen® may weaken condoms and vaginal diaphragms. Therefore, the use in combination with Veregen® is not recommended.
- Female patients using tampons should insert the tampon before applying the ointment. If the tampon is changed while the ointment is on the skin, accidental application of the ointment into the vagina must be avoided.
- Veregen® may stain clothing and bedding.
- Veregen® is not a cure and new warts might develop during or after a course of therapy. If new warts develop during the 16-week treatment period, these should also be treated with Veregen®.
- The effect of Veregen® on the transmission of genital/perianal warts is unknown.
- 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.
- The treatment area should not be bandaged or otherwise covered or wrapped as to be occlusive.
- Uncircumcised males treating warts under the foreskin should retract the foreskin and clean the area daily.
Carcinogenesis, Mutagenesis, Impairment of Fertility
In an oral (gavage) carcinogenicity study, sinecatechins was administered daily for 26 weeks to p53 transgenic mice at doses up to 500 mg/kg/day (22-fold MRHD; [see Use In Specific Populations]). Treatment with sinecatechins was not associated with an increased incidence of either neoplastic or non-neoplastic lesions in the organs and tissues examined. Veregen® has not been evaluated in a dermal carcinogenicity study.
Daily vaginal administration of Veregen® to rats from Day 4 before mating and throughout mating until Day 17 of gestation did not cause adverse effects on mating performance and fertility at doses up to 0.15 mL/rat/day. This dose corresponds to approximately 150 mg/rat/day (8-fold MRHD).
Use In Specific Populations
Pregnancy Category C
There are no adequate and well controlled studies in pregnant women. Veregen® should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
The Maximum Recommended Human Dose (MRHD) of Veregen® was set at three times daily topical administration of 250 mg, 750 mg total, containing 112.5 mg sinecatechins for the animal multiple of human exposure calculations presented in this labelling. Dose multiples were calculated based on the human equivalent dose (HED).
Embryo-fetal development studies were conducted in rats and rabbits using intravaginal and systemic routes of administration, respectively. Oral administration of sinecatechins during the period of organogenesis (gestational Days 6 to 15 in rats or 6 to 18 in rabbits) did not cause treatment related effects on embryo-fetal development or teratogenicity at doses of up to 1,000 mg/kg/day (86-fold MRHD in rats; 173-fold MRHD in rabbits).
In the presence of maternal toxicity (characterized by marked local irritation at the administration sites and decreased body weight and food consumption) in pregnant female rabbits, subcutaneous doses of 12 and 36 mg/kg/day of sinecatechins during the period of organogenesis (gestational Days 6 to 19) resulted in corresponding influences on fetal development including reduced fetal body weights and delays in skeletal ossification. No treatment related effects on embryo-fetal development were noted at 4 mg/kg/day (0.7-fold MRHD). There was no evidence of teratogenic effects at any of the doses evaluated in this study.
A combined fertility / embryo-fetal development study using daily vaginal administration of Veregen® to rats from Day 4 before mating and throughout mating until Day 17 of gestation did not show treatment-related effects on embryo-fetal development or teratogenicity at doses up to 0.15 mL/rat/day (8-fold MRHD).
A pre-and post-natal development study was conducted in rats using vaginal administration of Veregen® at doses of 0.05, 0.10 and 0.15 mL/rat/day from Day 6 of gestation through parturition and lactation. The high and intermediate dose levels of 0.15 (8-fold MRHD) and 0.10 mL/rat/day resulted in an increased mortality of the F0 dams, associated with indications of parturition complications. The high dose level of 0.15 mL/rat/day also resulted in an increased incidence of stillbirths. There were no other treatment-related effects on pre-and post-natal development, growth, reproduction and fertility at any dose tested.
It is not known whether topically applied Veregen® is excreted in breast milk.
Safety and effectiveness in pediatric patients have not been established.
Seven patients (1.4%), older than 65 years of age were treated with Veregen® in clinical studies. This, however, is an insufficient number of subjects to determine whether they respond differently from younger subjects.
