- Be confident of the diagnosis before treating any lesion with cryotherapy and if in doubt perform a biopsy or refer the patient to a specialist.
- Monitor the freeze time, spray in short bursts to maintain an ice-ball and stop when the desired freeze time is over.
- Warn patients about potential side effects including pain, redness, swelling, and blistering.
- Children do not tolerate cryotherapy well; therefore, consider alternative treatments.
