14 Common Medications with Bizarre and Unexpected Side Effects

9. The Antipsychotic That Causes Unusual Body Movements

Antipsychotic medications are essential for managing psychiatric disorders, but some have been associated with unusual and involuntary body movements, known as tardive dyskinesia. These movements can include repetitive facial grimacing, tongue movements, and limb jerking, which can be socially stigmatizing and physically uncomfortable. The underlying cause of this side effect is believed to be related to the drug's long-term effects on dopamine receptors in the brain, which play a crucial role in motor control. By investigating this phenomenon, researchers hope to develop new antipsychotic treatments that minimize the risk of movement disorders while effectively managing psychiatric symptoms.

10. The Cholesterol-Lowering Drug That Causes Muscle Pain

Cholesterol-lowering drugs, such as statins, are widely used to reduce the risk of cardiovascular disease, but some patients experience muscle pain as a side effect. This pain can range from mild discomfort to severe, debilitating aches that interfere with daily activities. The cause of this side effect is thought to involve the drug's impact on muscle cells and mitochondrial function, leading to increased oxidative stress and muscle damage. By studying this side effect, researchers aim to develop new strategies for managing cholesterol levels that minimize muscle-related complications, ultimately improving patient adherence and treatment outcomes.
