Final answer:
The correct term for medication taken from the pharmacy without compensation is not provided among the options, as normally all medications require payment unless specific arrangements like charitable services are in place. Overdoses occur when prescription or over-the-counter medicines, as well as illegal drugs, are taken in excess.
Step-by-step explanation:
The term for medication taken from the pharmacy without compensation is not directly specified in the options provided (A) Over-the-counter, (B) Generic medication, (C) Prescription drug, (D) Controlled substance. However, based on the context of the question, if the medication is not being paid for (without compensation), and assuming it is not being stolen or acquired through illegal means, it may perhaps be provided as part of a charitable service, assistance program, or through an insurance scheme that covers 100% of the cost. It's important to note that normally, all medications, whether they are over-the-counter, generic, prescription, or controlled substances, require compensation unless specific arrangements are made.
When discussing medication misuse, taking prescription or over-the-counter medicines in doses that are too high can lead to overdoses. Similarly, overdoses can occur with illegal drugs. An overdose signifies taking more of a substance, whether medication or an illegal drug, than is recommended or medically safe.
