Although you don't need a prescription to buy a light therapy box, it's best to ask your doctor or mental health provider if light therapy is a good option for you. Ask whether you need to take any special precautions. Also discuss which type of light therapy box would best meet your needs, so you get the most benefit and minimize possible side effects.
Internet retailers, drugstores and other stores offer a variety of light therapy boxes. Familiarize yourself with the variety of features and options available on light boxes to help ensure that you buy a high-quality product that's safe and effective. Health insurance companies rarely cover the cost.
