My wife has parkinson's disease in her family. so how dangerous is it for her to be taking haldol (haloperidol) and ativan?

Not enough data: Haldol (haloperidol) in sensitive people may give a side effect pseudo-Parkinson (tremors, stiffness, etc.) Ativan is anti-anxiety and have no relation to Parkinson. There are few other medications to substitute Haldol (haloperidol) for a less look-alike Parkinson.

Refer those question: s to her neurologist, who can best answer them. Parkinson drugs have their own side effect profile. So consult her or him first for your best answer. Both are sedating and it may mask her parkinson symptoms and extrapyramidal effects seen with haldol (haloperidol) may not be good with history of parkinsonism. Need a second opinion.

Not particularly: Haldol (haloperidol) won't cause the onset of Parkinson's disease. It can lead to parkinsonisms which are movement abnormalities seen in Parkinson's disease — such as tremor, slow movement, impaired speech or muscle stiffness. It is similar pathophysiology but still very different in the end, as stopping an inciting medication like Haldol (haloperidol) should resolve the issues.
