What the FDA labels say
From the Bromocriptine (CYCLOSET) label · effective 2026-01-12
Impulse Control/Compulsive Behaviors There have been reports of patients experiencing intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably, and/or other intense urges, and the inability to control these urges while taking one or more of the medications, including bromocriptine, that increase central dopaminergic tone.
From the Carbidopa, levodopa, and entacapone (Carbidopa, Levodopa and Entacapone) label · effective 2026-04-08
Hypotension, orthostatic hypotension, and syncope are observed in patients treated with drugs that increase central dopaminergic tone including Carbidopa, levodopa and entacapone tablets.
Patients may be unable to control these urges while taking one or more of the medications generally used for the treatment of Parkinson’s disease and which increase central dopaminergic tone, including entacapone taken with levodopa and carbidopa.
Although these adverse reactions may be related to the ergoline structure of these compounds, a possible causal role of nonergot derived drugs (e.g., entacapone, levodopa), which increase dopaminergic activity, has also been considered.
Four cases of pulmonary fibrosis have been reported during clinical development of entacapone; 3 of these patients were also treated with pergolide and 1 with bromocriptine.
Hallucinations and/or Psychotic-Like Behavior Dopaminergic therapy in patients with Parkinson’s disease has been associated with hallucinations.
