Does taking trazodone cause high blood pressure?

For me yes. My BP went to 160/105 and fast heart rate 120. I had a very dry mouth and stuffy nose. More serious effects that I had short breath or wake up suddenly gasping for air and feeling dizzy. I stopped it one night all these symptoms went away. Thank goodness it was just the effect of trazodone and that my heart and my lung were good after two visits to the emergency due to this medicine.

Hi, nana! You should let your doctor know, but this is a common side effect... and it can be hypertension (fast heart rate) or hypotension (slow heart rate). This side effect generally only lasts a few days to a week or so as you adjust to the medication.
"Common (1% to 10%): Hypertension, hypotension, tachycardia, palpitations."

I am asking because when I took trazodone my heart was pumping fast so Im not sure if I should continue the medication

I was put on trazodone 50mg @ night to help me sleep. I have always been on the hypotensive side (low blood pressure) but since starting this 3 months ago, I now have chronic sound of my heartbeat in my left ear, headaches, insomnia and now my BP is high! Anywhere from 112/92 to 136/98. And there is nothing in the side effects that match what is happening to me.

That's different than most of us. One reason I stop this medication was the blood pressure was too low.

I take 50mg of trazodone before bed. And my blood pressure has actually went down, since taking it. (Over two months now) at my last dr.appt last week bp was in the normal, to a little lower, range. It use to be higher than normal. So, I guess it depends on the dosage and the person. Good luck to your friend... Taylor

In around 1 - 5 % people who take trazodone blood pressure going up has been reported, in some case (around 7%) the blood pressure also does go down, these are common side effects of trazodone.

Take care, best wishes!
