Metex (methotrexate) should be protected from light, as exposure can affect its stability. Sunlight is particularly harmful due to the intensity and content of UV radiation. Standard electric light has much less effect, but for safety, it is recommended to store the drug in its original packaging and avoid prolonged exposure to light.
