Common side effects of Levodopa may include:

Levodopa, primarily used for treating Parkinson's disease, is known to have a distinct side effect profile. Among these, hallucinations and dyskinesia are particularly notable. Hallucinations may occur due to the dopaminergic activity of Levodopa, as it increases dopamine levels in the brain, which can sometimes lead to neuropsychiatric side effects. Dyskinesia, characterized by involuntary movements, typically results from long-term use of Levodopa as the body adjusts to fluctuating levels of dopamine over time. These effects are important for clinicians and patients to monitor and manage as part of the overall Parkinson's disease treatment plan.

Other common side effects, while present, do not encompass the key issues seen with Levodopa use in the same way that hallucinations and dyskinesia do, making this the most relevant choice.
