Final answer:
When you see CNS depression as a side effect, you should avoid substances or medications that can further depress the CNS, such as alcohol or barbiturates.
Step-by-step explanation:
When you see central nervous system (CNS) depression as a side effect, it is important to avoid substances or medications that can further depress the CNS. Examples of substances to avoid include alcohol, barbiturates, benzodiazepines, and opioids. CNS depressants slow down brain activity, leading to drowsiness, slowed breathing, and decreased mental function. Taking CNS depressants along with medications that cause CNS depression can increase the risk of severe respiratory depression, coma, or even death. It is important to consult with a healthcare professional before combining medications or substances that can depress the CNS to ensure safety.
