Which of the following medications is known to cause vivid dreams and has a risk of suicidality?

Efavirenz is known to be associated with vivid dreams and has been linked to an increased risk of suicidality among patients. This medication affects neurotransmitter systems in the brain, particularly those involved in sleep and mood regulation, which can lead to altered dream patterns such as vivid or bizarre dreams. Additionally, it is essential for clinicians to monitor patients on Efavirenz closely for any signs of mood changes, including suicidality, as this medication can exacerbate underlying mental health conditions or provoke them in predisposed individuals. The combination of these factors makes it crucial for healthcare providers to consider the psychological impacts of this medication when prescribing it to patients.
