I did some more research online into the drug Fortaz in use with reptiles and found out there could be some side effects - I'm not willing to risk her health for a "maybe". I will throw out the injections when I get home and leave her alone.
I have always relied on the breeder that I got her from for advise - he has been very helpful. His advise to me was to not do any further injections.
I will take a poop sample in to be checked as soon as I can get one from her - at least that would help rule out any parasites.
I just hope in the end - I am making the right decision for my baby.
