Well, I'm a little confused now because. I the 1 supposed to use, like every day a couple times, and then there was a different one that I thought it was only supposed to be used if the other one didn't work. But now the nurse just told me that I'm supposed to use them both, so I only got the one at the pharmacy so I don't really I don't really know. I feel like a bit confused now, but I always use the 1 supposed to be like 2 times a day, the one that starts with an "s", um but sometimes I just do it once a day if I forget the second one.
