I received bupropion ER 150 mg in place of the bupropion SR 150 mg I usually receive. We just switched to a mail order pharmacy and I want to verify that the medication I was given is the correct one.
No. Though not too dissimilar. The difference is in the number of doses taken per day. Bupropion ER where the ER stands for Extended Release and is taken only once per day usually in the morning has a tablet that releases the medicine very slowly over an extended period of time (approx. 24 hours) hence the ER. Bupropion SR is Sustained Release and is most often taken two times per day. It's tablets release a steady concentration of medicine throughout the day but not for 24 hours. IE. It's a sustained concentration but not extended to 24 hours like the ER formula. The take home is that one (bupropion ER) need only be taken once a day whereas the other (bupropion SR) is most often taken twice a day.
depressed; I am sorry we are getting this more confused for you. I well tell you again, Then just for your own CALL YOUR PHARMACIST AND DOUBLE CHECK THIS. This is a very common confusion even in the pharmacy and the doctor. FIRST BUPROPION ER (EXTENDED RELEASE ) 150MG IS THE SAME AS THE Bupropion ER ( EXTENDED RELEASE) OR SR ARE THE SAME SEE er is on all the timed release and these two about are taken twice daily like every 12 hours, Then here is where the confusion comes in WE HAVE Bupropion ER (extended release) XL AND THAT IS THE 24 HOUR ONE. AS YOU CAN SEE THEY ALL SAYs ER FOR extended release which they are all extended-release tablets the ER AND SR ARE THE SAME AND THE Xl extended release is for a 24-hour dose. now please call the PHARMACIST phone on your bottle and verify what I have put down. Good luck this is one of the worst medication for the Extended Release confusion.
The difference between the two are that the ER is Extended release and the SR is Sustained release. I hope this helps! Hugs
