Verapamil Sa Versus Er
(Newest replies first)

I started out on 40mgs Verapamil SA for High Blood Pressure and PSVT...It was not enough, increased to 120mgs ER once pr day...That worked longer.. But had to go up to Verapamil 240mgs. That was the magic dose...Did really well on that dose. Awhile back, I noted my PSVT seemed to be acting up more often and my BP raised up.....I just noticed on my Rx bottle that the V.A. Pharmacy started sending me the right dose. But, it was Verapamil 240mg SA (Instead of my usual 240mgs ER.)...Dr. didn't order the change. But, I have noticed I don't do as well on one 240mg SA as I do on the 240mgs ER.....(Beginning to wonder is SA is "short Acting?)....Again Dr. didn't order the change....Obviously, the ER is better for me.

Hi..I thought maybe they were different because I have been experiencing more heart racing episodes recently since switching from ER to SA.... However, I have also long been Dx'ed with Anxiety / Panic Disorder and OCD as well.....If the ER and SA are the same thing, perhaps I am dealing more with my Anxiety /OCD acting up... Either that or 240mgs once a days isn't cutting it for my PSVT anymore. I have contacted my Dr. but don't expect to hear back until after Christmas...Thank you for the reply!!! I really liked this med as I have never had "any" side effects from it.....Thanks again! -- Karen

No, the SA actually stands for sustained action, so both it and the ER mean the same thing, they are both abbreviations that note it as being time released.

The FDA lists its typical side effects as possibly including nausea, dizziness, headache, increased urination, and hypotension.

What symptoms are you experiencing that make you think it isn't working as well for you?
