Common warts on fingers

Common warts are a relatively common disease and a skin problem that occurs to many people. Of course, common warts generally do not cause any harm to patients, but some patients will experience pain after getting common warts. In this case, certain treatment measures need to be taken. Below, we will introduce to you in detail the treatment methods of common warts!

1. Systemic treatment

(1) Traditional Chinese medicine, such as Pinggan Huoxue prescription, Zhiyou decoction, Purslane mixture, Isatis root injection, Bupleurum injection, etc.

(2) Interferon: For multiple and stubborn warts, interferon can be combined with systemic or local injection of lesions. The efficacy of interferon alone is uncertain.

2. Local drug treatment

Since most warts disappear on their own within 1 to 2 years after onset, and even with deep destructive treatments, one-third of warts will still recur, the efficacy of various local treatments for warts should be evaluated with caution, and some methods that can cause permanent scars should not be used.

(1) Fluorouracil (5-FU) has a certain therapeutic effect. Possible adverse reactions include local pain, chapped skin, edema, allergic reaction, tearing, pigmentation and suppuration.

(2) Intralesional injection of bleomycin is once a week. Warts usually fall off after 2 to 3 injections, with few side effects.

(3) 0.7% cantharidin is added to equal amounts of collodion and acetone solution and applied externally to treat periungual warts. Apply once every other day and it has a certain therapeutic effect.

(4) 0.1%-0.3% retinoic acid alcohol solution: For topical use, 1-2 times a day. Side effects include mild local burning sensation, redness, swelling, desquamation, and pigmentation.

(5) 3% phthalamide ointment or 3% phthalamide dimethyl sulfoxide lotion.

(6) 0.5% podophyllotoxin, twice a day for 3 consecutive days. If tolerated, it can be used for 4 to 5 days. If the warts have not fallen off, you can continue the treatment every other week.

(7) 5% imiquimod cream can be used for occlusive treatment of common warts or in combination with salicylic acid treatment.

(8) Topical application of 1% cidofovir gel or intralesional injection of 2.5 mg/ml is effective for various warts.

3. Photodynamic therapy

Systemic or topical use of the photosensitizer aminolevulinic acid or aminolevulinic acid (ALA) can treat some common warts by inducing local cell death after light exposure.
