There are some pharmaceutical companies that offer free medications to low-income families. They require a doctor's consent and proof of your financial status. Depending on what your insurance covers, you may be able to apply. A few companies even allow family incomes as high as $40,000 annually (offset by expenses, of course). Here is a list of psychotropic medications with corresponding companies that feature patient-assistance programs and their contact numbers.

Note: Some of these companies may prefer to speak directly with your doctor.
