Hi, I have a question about Sinemet and why it may be contraindicated when someone has asthma. I have had serious asthma for years, usually under good control, although I have an attack about twice a year, like I did yesterday. I've read something about Sinemet affecting smooth muscles like those in the respiratory tract. Anybody else have any info? Thanks, Connie ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
