Diagnosed With Parkinson. What Medications Should Be Given To Address Medication Induced Vomiting And Nausea?
Thank you for posting your query.
The first choice drug for medication-induced vomiting and nausea, especially in patients with idiopathic Parkinson's disease (PD), would be domperidone. This is because it does not cross the blood-brain barrier and hence, has no extrapyramidal side effects and does not worsen tremors, rigidity, involuntary movements, etc. Domperidone is widely used in many countries including India, however, due to some reason, not yet available on prescription in US.
The other drug, which I find very useful, is ondansetron. Though this drug is specific for chemotherapy induced vomiting and nausea, it is useful in cases of PD also.
We should avoid drugs such as metoclopramide, as it crosses blood brain barrier, and causes side effects in patients with PD.
I hope it helps. Please get back if you have any more queries.

Thank you for your response. I greatly appreciate your professional opinion.
Since my stepmother lives in the US, Domperidone is not viable at this time.
As for ondansetron, since it is specific for chemotherapy induced vomiting and nausea, other medications have been mentioned/suggested.
Can you please review the medications below and advise accordingly:
Tigan
Benzacot
Tebomide
Ticon
Thank you in advance.

The medications you have mentioned are all same- different brand names for trimethobenzamide.
It is a safe and effective drug to control nausea and vomiting. It acts on the vomiting centre located in the medulla oblongata of brain.
It is generally available as oral capsules and injections.
