Flura [38]

The adverse effects of levodopa therapy on orthostatic hypotension would support the nursing diagnosis of injury risk.

Parkinson's disease is treated with a combination of levodopa and carbidopa. The most effective treatment for Parkinson's disease motor symptoms is levodopa/carbidopa. More than 50 years ago, levodopa was discovered as a treatment for Parkinson's disease.

Dyskinesias are uncontrollable, sudden movements. These are known as motor symptoms and are a common side effect of long-term levadopa use. Dyskinesias can have an impact on one's quality of life. The severity of these levodopa-related symptoms varies. Dykinesia is more common in early-onset Parkinson's disease. To prevent motor symptoms, drugs may be added or changed.

Orthostatic hypotension, also known as postural hypotension, is a type of low blood pressure that occurs after sitting or lying down. Orthostatic hypotension can result in dizziness, lightheadedness, and fainting. Orthostatic hypotension is not always severe. Episodes could be brief.
