Hello, I was on meridia about 2 years ago. I was on if for 7 months and lost about 50# on it, then one day at a dr. appt., they took my b/p and it was very high so I had to stop taking it. I continue to have high b/p. I'm not saying that it will happen to you, it may help you and you can continue taking it with no complications. I'm not taking anything now, but wish I could be on something to help me. I even considered surgery but it didn't work out, I guess I'll have to do it the old fashioned way...
