There are plenty of programs available from pharmaceutical companies to assist people who are having difficulties paying for their medications, such as the Lilly Cares Program.
Other companies have similar services and will have up-to-date information on their websites.
Many insurance companies include a drug benefit as part of their plan, so often only a co-payment is necessary, and the ever-changing Medicare guidelines have provisions for medication costs as well.
Also, many psychiatrists have sample packs of medications that they can give people to start them off on medications. They also occasionally get vouchers from pharmaceutical representatives, which can be used to help patients pay for medications.
If you are having difficulties with paying for medications, your psychiatrist may be your best help because he or she will most likely have the information necessary for you to contact the drug companies to request specific assistance.
