LEQSELVI

What is this medication? LEQSELVI is a prescription medication used to treat adults who have severe alopecia areata, an autoimmune condition where the body attacks its own hair follicles, causing significant hair loss on the scalp and body. It belongs to a category of drugs known as Janus kinase inhibitors, or JAK inhibitors, and specifically targets the JAK1 and JAK2 enzymes. By blocking these enzymes, the medication helps to calm the overactive immune response that causes hair loss, which may allow for hair regrowth in patients with extensive symptoms.

This medication is an oral tablet that is generally taken twice each day. It was approved by the FDA as a targeted treatment option for patients who require a systemic approach to managing severe cases of alopecia. Because it works by modifying the immune system, healthcare providers typically monitor patients for potential side effects and perform regular blood tests to ensure the treatment is being tolerated safely.
