Despite considerable searching through my diet and supplements for sources of substances known to interact with Azilect causing hypertension I still experience a mild rise in b/p for 5-6 hours. For example, in the am before any meds or food my b/p can be 115 to 125. Then I take Azilect with water and no food and starting in about an hour and a half my b/p begins to rise but not so much as to be alarming just to the upper 130s and lower 140s. The b/p peaks in about 3 hrs then gradually returns to normal. Before I removed green tea's theanine substance from my routine my b/p was rising to way over 150. Now I believe I could live with taking Azilect on an empty stomach and with no other meds or food for 6 hrs. but I'd rather have a more normal morning so I am going to make a gradual change in the time of day for Azilect to bedtime, which is also when I take an aspiring for blood thinner. I hope this works out because I feel that Azilect has helped control my PD and I've only taken it for a couple months.
