Which statement about safety in drug testing is true?

The statement that all side effects must be reported regardless of significance is true because comprehensive safety monitoring is a crucial aspect of drug testing. When a new medication is tested, it is important for researchers and regulatory bodies to gather as much information as possible about various side effects that may occur. This includes both serious and non-serious effects.

Reporting all side effects helps in understanding the overall safety profile of the drug, as even minor side effects might indicate potential long-term risks or may be associated with specific populations. The continuous collection of safety data is a key component of post-marketing surveillance, which allows regulators to monitor the drug's safety in the general population over time, and this ongoing review can lead to important health and safety information that might not have been evident during the initial clinical trials.

Inadequate reporting could potentially overlook significant public health issues that arise from less serious but prevalent side effects, reinforcing the necessity of comprehensive monitoring in ensuring drug safety.
