Imiquimod
"Using this for basal call carcinoma treatment. Used it for a couple of small areas initially with little problems. Have been using it on a larger spot now, and have developed quite significant flu like symptoms. Have tried to push through them, but they're getting worse to the point of needing to stop the cream. Extremely fatigued and achy, which is just not me. I work out an hour plus several days a week and am only able to struggle through maybe a half work out. It also caused a lot of redness and sores at the site of use, but I can manage that. The good news is it does seem to work on the basal cells."
