Follow Up
- Patients undergoing therapy should be advised to return weekly for treatment until all the warts are removed in order to:
- Monitor response to therapy, ie treatment response is mostly noted within 3 months of therapy
- Assess need for changes in treatment modalities
- Evaluate recurrence
- Assess need for specialist referral
- Patients whose original lesions have responded well to treatment but in whom new lesions are developing can continue with current regimen
- Change in therapy is indicated if the patient is not tolerating current therapy, with severe side effects or <50% response to current treatment after 16 weeks for Imiquimod and 6 weeks for other modalities
- Patients concerned about recurrence may be evaluated 3 months after successful treatment
- Relapses should be treated according to the lesion types
Specialist Referral
- Consider specialist referral in the following patients:
- Large-volume disseminated disease
- Intractable lesions
- Immunocompromised patients
- Pregnant patients
- Children
