14 Common Medications with Bizarre and Unexpected Side Effects
11. The Sleep Aid That Causes Sleepwalking

Sleep aids are designed to help individuals achieve restful sleep, but some have been linked to sleepwalking, a behavior that can be dangerous and disruptive. Sleepwalking episodes can involve complex activities, such as eating, driving, or even engaging in conversations, all while the individual remains unaware. The cause of this side effect is believed to be related to the drug's impact on the brain's sleep architecture and the transition between different sleep stages. By exploring this phenomenon, researchers hope to gain insights into the mechanisms of sleep disorders and develop safer sleep aids that reduce the risk of sleepwalking and other parasomnias.
12. The Weight Loss Drug That Affects Mood

Weight loss drugs can be effective in helping individuals achieve their health goals, but some have been reported to affect mood, leading to symptoms of depression or anxiety. This side effect can undermine the benefits of weight loss by impacting mental health and overall well-being. The cause of this mood alteration is thought to involve the drug's impact on neurotransmitter levels and the brain's reward pathways, which are closely linked to mood regulation. By studying this side effect, researchers aim to develop weight loss treatments that support both physical and mental health, ensuring a holistic approach to patient care.
