There are two kinds of verapamil dosage forms.
One is the immediate release. Has no abbreviations after it.
The other is extended release. Some drug companies use various abbreviations for it... ER, XL, SA, etc.
One drug Cardizem has a very confusing set of abbreviations after it, for example.
Cardizem immediate release (no letters after the name)
Cardizem SR-- to be used twice a day --sustained release
Cardizem CD-- Once a day dose..generics use ER also for this
Cardizem LA-- a special dosage form to only be taken at night
Verapamil does come in the special night time release form, for hypertensive patients who do not have "dipping" --which is a lowering of blood pressure during sleep. The makers of Calan have a verapamil for night time only called Covera HS.
It is available as Verelan PM as brand and generic, in CAPSULE form. Both are to be given at night.
It appears that the tablets only, for verapamil, are the older form of extended release. If your RX is tablets, it is listed at the Orange Book as extended release. ER and SA are commonly interchanged.
If no SA or ER appears after the name, then the verapamil is immediate release and this can be a serious error, because they are not interchangeable. However, there is no immediate release made in 240mg size. Only in 120mg.
Here is a list of all the generics and brands available for verapamil. See if your brand (manufacturer) is on this FDA list.
I'd put up a link, but FDA does not have internal links, only generic addys.

It has been my experience that the abbreviations after drug names for extended release are confusing. My Cardizem CD generic is now caller ER.
Calan SR does not appear on the FDA list. The other brand of long acting verapamil was Isoptin SR. They both shared the patent at one time. Neither was originally called SA.
So the bottom line? SA (sustained action),SR (sustained release) ER (extended release), XL (extended length), LA (long acting) are sometimes used interchangeably with drugs that are long acting. It can be very confusing.
For Verapamil... tablets are not generically interchangeable with capsules as a rule. The HS or PM form is not interchangeable with the regular extended release type (but these have no generic).
The immediate release type does not come in 240mg size so this does not affect you.
If you had extended release verapamil tablets, then you should continue with tablet form of 240mg.
My generic Cardizem CD does not have CD after it...it has ER.
I think they are trying to unify the abbreviations now, so that there will not be so many that are confusing to both doctors, pharmacists and patients.
You can look up your tablets for verification at
www.rxlist.com
That website has an ID checker...you type in the letters/numbers off the tablets and it identifies the drug.
