I guess you never took a simple psych course when they yammer on for a chapter about abnormal psych? Never heard of tardive dyskinesia?

Side Effects
The side effects of L-DOPA may include:
* Hypotension, especially if the dosage is too high
* Arrhythmias, although these are uncommon
* Nausea, which is often reduced by taking the drug with food, although protein interferes with drug absorption
* Gastrointestinal bleeding
* Disturbed respiration, which is not always harmful, and can actually benefit patients with upper airway obstruction
* Hair loss
* Disorientation and confusion
* Extreme emotional states, particularly anxiety, but also excessive libido
* Vivid dreams and/or insomnia
* Auditory and/or visual hallucinations
* Effects on learning; there is some evidence that it improves working memory, while impairing other complex functions
* Somnolence and narcolepsy
* A condition similar to stimulant psychosis
Although there are many adverse effects associated with L-DOPA, particularly psychiatric ones, it has fewer than other antiparkinsonian agents, such as anticholinergics and dopamine receptor agonists.
More serious are the effects of chronic levodopa administration, which include:
* End-of-dose deterioration of function
* On/off oscillations
* Freezing during movement
* Dose failure (drug resistance)
* Dyskinesia at peak dose
* Recent studies have demonstrated that use of L-DOPA without simultaneously giving proper levels of serotonin percursors depletes serotonin
* The long term use of L-DOPA in PD has been linked to the so called dopamine dysregulation syndrome.[3]
Clinicians will try to avoid these side effects by limiting L-DOPA doses as much as possible until absolutely necessary.
