What is the correct dose for this ambroxol, guaifenesin and terbutaline combination cough syrup?

The dose for this syrup really depends on the person's age, weight and how bad the cough is, so there isn't one single answer that fits everyone. Typically it's measured in a few millilitres given two to three times a day, but children, elderly patients and those with heart or thyroid issues often need adjusted amounts. It's best to go by what's written on your prescription or check with your doctor or pharmacist so you're not over- or under-dosing it.
