If you notice a rough, round bump on your finger that seemed to appear out of nowhere, you may have a wart. Warts that appear on the fingers are known as common warts and are caused by the human papillomavirus, says the Mayo Clinic 12. In most cases, warts on the fingers are not a serious medical condition. If your doctor approves, you can use home remedies to treat warts on your fingers.
Applying duct tape to a wart for several days may help reduce a wart more effectively than over-the-counter remedies like salicylic acid, says the Mayo Clinic. Placing duct tape over the wart may irritate the wart so that the body's immune system will naturally attack it. Cut a small piece of duct tape that slightly overlaps the wart, then apply it directly to the skin. Leave the duct tape on for six days, then remove it and carefully file the wart with a pumice stone. Place another piece of duct tape on the wart, then leave it on for six more days. Continue this process until the wart is completely gone, recommends the Mayo Clinic.

What Causes Common Finger Warts?
Placing vitamin A on the wart may help remove it, says Robert Garry, Ph.D., an associate professor of microbiology and immunology at Tulane University School of Medicine. Dr. Garry recommends cutting open a capsule that contains 25,000 international units of vitamin A, then squeezing the liquid directly onto the wart once a day. This treatment may take between two and four months to be effective, says Dr. Garry.
Placing a medical tape bandage over the afflicted finger may be effective in removing warts, says Thomas Goodman, Jr., M.D., an assistant professor of dermatology at the University of Tennessee Center for Health Sciences. Wrap a piece of medical tape snugly, but not so tight as to cut off circulation, on the finger. Leave the tape on the finger, and change it only when it gets dirty or begins to peel off your finger. Continue to check underneath the tape periodically until the wart is completely gone.
