"*Instead of tablets, you can take Valbazen (Albendazole) Oral Suspension for Cattle & Sheep. It contains 11.36% or 113.6mg/ml of Albendazole. Use an oral syringe to measure 3.5ml, which equals a 400mg tablet. Mix into beverage or soft food to mask the blah taste. May add sugar or other sweetener."
As noted in the protocol, Valbazen 3.5ml = Albendazole Tablet 400mg.
The 3.5ml dosage isn't based on weight; it's based on equivalency to tablet.
Suggest you print a copy of the protocol to cover any other questions you may have.
