Final answer:
OTC drugs are medications safe for unsupervised use and can be bought without a prescription, regulated by the FDA. Schedule V drugs, however, still require a prescription and are not available over-the-counter.
Step-by-step explanation:
Over-the-counter (OTC) drugs are medications that can be purchased without a prescription. These include common pain relievers like aspirin and ibuprofen. The FDA oversees the regulation of OTC drugs and maintains a list of ingredients that are deemed safe for OTC use. Former prescription drugs, like certain antihistamines and analgesics, may be reclassified as OTC after they are found to be safe for self-administration.
When it comes to C5 prescriptions, or Schedule V controlled substances, these medications still require a prescription due to potential risks. They cannot be sold over the counter. Although the FDA's list of approved OTC ingredients is extensive, only those drugs evaluated and considered safe for unsupervised use by consumers make the change from prescription to OTC status. As such, while Ebola Treatment might be discussed in various contexts, it's not related to the typical OTC product landscape.
