Intralesional triamcinolone acetonide suspension of 2.5 mg/mL into the proximal nail fold is very helpful for nail matrix psoriasis (eg, pitting, ridging, leukonychia). This medication may be administered every 4-6 weeks. The proximal nail fold is sprayed first with a refrigerant spray for anesthesia, and the injection is given with a 30-gauge needle.
