Hi, i've recently been prescribed diltiazem, but don't have any real instruction on how to use it, just says apply twice daily, prior to using this I was using nitro which I thought was similar in terms of application but now it seems not, as nitro can be inserted into the rectum and is clearly marked on the packaging (rectal use), diltiazem can only be applied externally (says on the tub), or can it be used inside the rectum too?
Thanks in advance for your help
