Hi David, This is the information I have from a Canadian drug index: Levodopa/carbidopa should not be taken by people with active cardiovascular, endocrine, blood related, liver, lung (including bronchial asthma), or kidney disease; or by people with narrow angle glaucoma. Other references state that there are special warnings (not specified) for patients with the following conditions: Bronchial asthma Cardiovascular or lung disease (severe) Endocrine (glandular) disorder History of heart attack or heartbeat irregularity History of active peptic ulcer Kidney disorder Liver disorder Wide-angle glaucoma (pressure in the eye) Maybe your friend has some more insight on these "warnings." Thanks, Connie [log in to unmask] writes: > >I posed your question to a friend who is a Kaiser Hospital allergist and >he >wrote back: > >>I've never heard of that contraindication. > > ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
