I have a kid scouring this morning; I have Di-Methox liquid (it says injectable on it) that says 40% on the label. I got it from Hoegger's. It says, each mL contains 400 mg sulfadimethoxine compounded with 20% propylene glycol, 1% benzyl alcohol, 0.1 mg disodium edetate, 1 mg sodium formaldehyde sulfoxylate and ph adjusted with sodium hydroxide. Now, I didn't realize that this wasn't the same Di-Methox that everyone else is using because I did get it from Hoegger's! So I gave the kid 5 cc of it this morning orally, because I thought it was supposed to be oral. So now I am thinking I gave too much! Help? On dosage, it says To be administered in amopunts to provide 25 mg/lb for initial dose followed by 12.5 mg/lb for maintenance doses every 24 hours.
