Thank you for posting your query.
I have noted your wife's symptoms. I would like to point out that prochlorperazine
is not very effective in controlling motion sickness
Better alternatives for preventing motion sickness include scopolamine
Please discuss these options with your doctor. Most of these are available as over the counter medicines.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
