I have pulmonary arterial hypertension (PAH) and am on several medications (Adempas, Letiris, Tyvaso-an inhaler, water pills/potassium). I just recently restarted back taking the adempas & am being monitored by a nurse, bi-weekly ( to retitrate me by keeping check on my blood pressure & making sure I don t have bleeding side effects--which was the reason I d been taken off of adempas for a couple months. I also am supposed to be on a c-pap nightly, but haven t done so in over 8 months. My concern is, for the past few weeks when I go to bed nightly, I sleep with my mouth open along with excessive drooling!! A friend mentioned this may be a sign of a stroke? Also, I m also supposed to be taking Xarelto-- per my physician, but due to unaffordabilty & bleeding episodes I haven t been taking them (though I received some samples recently from my doctor & will restart them today or tomorrow). Is this excessive drooling a sign of a stroke?? And what is your advice?
