Wow! A couple of days ago for cause, I decided to monitor my b/p. I found I was becoming hypertensive starting a couple of hours after taking the 1 mg Azilect on an empty stomach-no food interaction. I then researched and read that Azilect's half-life or peak of absorption is around 3 hours so Azilect is just doing what Azilect is known to do. However, I have an enlarged aortic arch and don't want aneurysm so I have decided to give a half a dose twice a day a try. Sure I have contacted the prescribing doctor but it's a holiday weekend and I thought while waiting to hear from his office someone here might have some experience to relate. This morning the half dose practice worked well for limiting the b/p to mild hypertension. I especially wonder if there is a divided dose regimen that was recommended to anyone here. Another day another PD obstacle analyzed and managed.
