Misprescribing & overprescribing of drugs
The numbers are staggering: in 2003, an estimated 3.4 billion prescriptions were filled in retail drugstores and by mail order in the United States. That averages out to 11.7 prescriptions filled for each of the 290 million people in this country. But many people do not get any prescriptions filled in a given year, so it is also important to find out how many prescriptions are filled by those who fill one or more prescriptions. In a study based on data from 2000, more than twice as many prescriptions were filled for those 65 and older (23.5 prescriptions per year) than for those younger than 65 (10.1 prescriptions per year).
Drug-induced parkinsonism has developed in 61,000 older adults also due to the use of antipsychotic drugs such as haloperidol (HALDOL), chlorpromazine (THORAZINE), thioridazine (MELLARIL), trifluoperazine (STELAZINE), and fluphenazine (PROLIXIN). There are other parkinsonism-inducing drugs as well, such as metoclopramide (REGLAN), prochlorperazine (COMPAZINE), and promethazine (PHENERGAN), prescribed for gastrointestinal problems.11 (See list of drugs that can cause parkinsonism.)
