Perhaps the doctor is trying to treat on
after the other so that the medications
don't cancel eachother out. I am not sure
though but if he actually states that it
is the same treatment then it might
actually be similar treatments.... I am
not sure but that is my opinion. If you
want, do more research on the medications
and see what they treat, if they cancel
eachother out, what makes up the
medications and compare them.
Also if she did the test and came out
positive for those stds perhaps you should
do a test yourself

not saying that you two have had sex with
tons of people or anything like that...
But to be on the safe side
wish you to best of luck, sorry if I
wasn't that much of help... But good
luck...
