Is this bottle of PraziPro still good for use?

[Brad Coughlan]

I am going to give a second attempt to curing my fish of flukes (in the display tank)

The first attempt failed because I did not shake the bottle. On the second attempt, will this same bottle be suitable for use? Since the praziquantel might've set at the bottom of the bottle, causing the next dose to be stronger and more concentrated, I don't want to overdose it

I guess you could use it but without knowing what amount you removed in the first treatment (-settlement, if any) it is not very easy to guess what concentration you now have or how much to use to administer the proper dosage.

The bottle instructions say do not overdose the tank so there’s that point to consider.

Shake it well, yes. It will not make the solution stronger but rather correct.
To be safe , dose at 85% of recommended and apply initial dosage known as an interval for 8 days, do a water change and do one more 8 day dose interval
Use airstone with prazi as it does reduce both oxygen and appetite. If running a skimmer, leave cup off first 24 hrs as skimmer will go nuts from the glycol solution in Prazi
