Major

Dopamine agonists (applies to carbidopa) hypotension

Major Potential Hazard, Moderate plausibility.

Dopamine agonists may impair the systemic regulation of blood pressure, with resultant orthostatic hypotension, especially during dose escalation. Therapy with dopamine agonists should be monitored carefully in patients with Parkinson's disease since they may have an impaired ability to respond to an orthostatic challenge, and also in patients receiving antihypertensive drugs.

Major

Dopaminergic antiparkinson agents (applies to carbidopa) psychosis

Major Potential Hazard, Moderate plausibility.

Ordinarily, patients with major psychotic disorder should not be treated with dopaminergic antiparkinson agents, because of the risk of exacerbating psychosis. Hallucinations and psychotic-like behavior have been reported with dopaminergic medications. In addition, certain medications used to treat psychosis may exacerbate the symptoms of Parkinson's disease and may decrease the effectiveness of these drugs.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
