Which type of substance does not require a prescription in the state of Indiana?

Over-the-counter medications are substances that can be purchased without a prescription. In the context of pharmacy practice, these medications are typically deemed safe and effective for use by the general public without the need for a healthcare provider's oversight. This makes them accessible for consumers who may seek treatment for minor ailments or symptoms without the necessity of an appointment or prescription.

In Indiana, as in many other states, over-the-counter medications include a variety of drug classes ranging from pain relievers and cold medications to topical treatments and dietary supplements. These products are regulated but are not classified as controlled substances, which require a prescription under various schedules.

Controlled substances, such as C-II and C-III drugs, are regulated more strictly due to their potential for abuse or dependency. These classifications make it necessary for patients to obtain a prescription from a licensed practitioner before accessing these medications, underscoring the difference in regulatory requirements compared to over-the-counter medications. Similarly, the broader category of controlled substances encompasses all substances that have the potential for abuse, further requiring prescriptions for legal distribution.
