I just wanted to get opinions on whether a prescrided dose should be reduced when injecting more that one type of antibiotic at the same time.

For example, if I was injecting only Baythril and the dose required is 1cc, should I reduce that dose if I was to inject a combination of Baythril and Azactam?

Also, how do injections affect the koi's liver?

Thanks in advance.
