Jylamvo is a prescription medication primarily used in the treatment of various forms of arthritis, including juvenile idiopathic arthritis, and certain skin conditions like psoriasis. It contains methotrexate as its active ingredient, which belongs to a class of drugs known as antimetabolites. Methotrexate works by inhibiting the activity of an enzyme involved in the rapid growth of cells, which helps to reduce inflammation and slow down the progression of the disease. Jylamvo is formulated as an oral solution, making it an alternative for patients who have difficulty swallowing pills or require precise dosing adjustments. It is important for patients to follow their healthcare provider's instructions closely when taking Jylamvo, as it can cause serious side effects, and regular monitoring may be necessary to ensure its safe use.
