Interferons are not recommended as a primary treatment modality. [3]

Naturally produced proteins with antiviral, antitumor, and immunomodulatory actions. Alpha, beta, and gamma interferons exist and may be administered topically, systemically, and intralesionally. Topical, systemic, and intralesional interferons are not efficacious.

Interferon alfa-n3 (Alferon N)

Alpha interferon has been approved by FDA for injectional use in refractory condyloma acuminatum with some possible benefit. Alferon N is interferon alpha-n3, which has been used effectively for this purpose.

Recurrence rate of 20-40% exists with intralesional interferon, but recurrence rate after successful treatment is lower than with other treatment modalities. Additionally, intralesional interferon is expensive and requires repeat office visits.

Furthermore, numerous adverse reactions may occur, including myalgias, fever, chills, GI symptoms, transient leukopenia, thrombocytopenia, LFT abnormalities, serum lipid abnormalities with intramuscular interferon, and theoretical risk of viral transmission with natural interferon products. Viral symptoms do abate with time, and all adverse effects resolve once therapy is stopped. Viral symptoms can be treated with acetaminophen or NSAIDs in the interim.
