i've read adding ENTACAPONE to carbidopa/levodopa (which = stalevo) may extend the interval between doses by 30-60 minutes so it doesn't have a major affect. it allows more l-dopa to get into the brain and last longer after it gets inside. amantadine can help movement and reduce dyskinesia's, involuntary movement. i know some people taking more stalevo than your husband, amantadine and an agonist so he doesn't seem to be taking a lot of meds but i'm not a doctor. so if your husband isn't experiencing major side affects from his meds like hallucinations, low/hi blood pressure, etc., i'd talk to his doc asap to evaluate his meds and try to get him not freezing and better treat his symptoms. with exercise being so important in general health and making one's pd symptoms possibly less severe, i feel you take the meds you need to keep exercising and have a social life.


switching back to sinemet is up to you and your doc, can't comment on that.
that said, it can take awhile to adjust meds and even add an agonist which means you want to find the best neuro/movement disorder specialist you can find. good luck.
