The cost of drug therapy can vary depending on the type of drugs prescribed and the length of treatment. In general, however, drug therapy is a costly endeavor. A single course of treatment can easily cost thousands of dollars, and many patients require multiple courses of treatment in order to achieve remission. In addition, patients often incur significant out-of-pocket costs for co-pays and deductibles. As a result, drug therapy can be a major financial burden for patients and their families. However, there are many programs and therapies available to help patients afford their medication. For example, some pharmaceutical companies offer patient assistance programs that provide free or discounted medication. In addition, many insurance plans cover the cost of drug therapy. As a result, patients should speak with their doctor or pharmacist about ways to reduce the cost of their medication.
