Hmmm. Interesting. I'm planning my own VBAC - any day now - and have been taking the tablets for about 4 weeks. My OB said it was fine to take.
Same - I planned a vbac for my second child, ended in another c-section but not because of RLT - but my OB was fine with me taking it and my midwives for child 3 and 4 didn't warn me off it either.

And obviously I didn't explode..... soooo......
