Medications To Avoid

Medications to avoid (or use with caution) for people with Parkinson’s disease.

This medication list is not intended to be complete and additional brand names may be found for each medication. Every patient is different, and you may need to take one of these medications despite caution against it. Please discuss your particular situation with your physician and do not stop any medication that you are currently taking without first seeking advice from your physician. Most medications should be tapered off and not stopped suddenly. Although you may not be taking these medications at home, one of these medications may be introduced while hospitalized.

If a hospitalization is planned, please have your neurologist contact your treating physician in the hospital to advise which medications should be avoided.

Medications to be avoided or used with caution in combination with Selegiline HCL (Zelapar®), Rasagiline (Azilect®) and Safinamide (Xadago®)

Medications to be avoided or used with caution in all patients with Parkinson’s disease

Medication TypeMedication Name Trade Name®Mechanism of Action
Typical AntipsychoticsChlorpromazineBlock D2 (dopamine)
receptors in the brain, which
can worsen Parkinson’s
symptoms
Fluphenazine
HaloperidolHaldol
Loxapine
Thioridazine
Thiothixene
Trifluoperazine
PimozideOrap
Perphenazine
Atypical Antipsychotics
(see note below)
RisperidoneRisperdalBlock dopamine receptors,
but dissociate from the
receptor more quickly than
typical antipsychotics. They
also tend to block serotonin
receptors in addition to
dopamine receptors. The
result is less parkinsonism
than that caused by the
typical antipsychotics.
OlanzapineZyprexa
ZiprasidoneGeodon
AripiprazoleAbilify
LurasidoneLatuda
PaliperidoneInvega
IloperidoneFanapt

vomiting)
ChlorpromazineBlock D2 (dopamine)
receptors in the brain, which
can worsen Parkinson’s
symptoms
DroperidolInapsine
MetoclopramideReglan
Prochlorperazine
Promethazine
Drugs to treat hyperkinetic
movements
such as chorea
and tardive dyskinesia
TetrabenazineXenazineDecrease dopamine stores
DeutetrabenazineAustedo
ValbenazineIngrezza
AntihypertensivesMethyldopaInhibits an enzyme which
converts L-dopa into
dopamine in the brain
AntidepressantsAmoxapineAlthough classified as a
tricyclic antidepressant, it
can also block dopamine
receptors

Note: If an antipsychotic that blocks dopamine receptors needs to be used, atypical antipsychotics are better choices than typical antipsychotics. Clozapine (Clozaril®) and Quetiapine (Seroquel®) are dopamine blockers with the least risk of worsening Parkinson symptoms. Pimavanserin (Nuplazid®) is a serotonin inverse agonist and was approved specifically for use as an antipsychotic in patients with Parkinson’s disease.
