The highest dose in a 24 hr period I used when I had a severe lung viral infection over 2 yrs ago was 80mg total per day.
Dextromethorphan is being somewhat controlled by most states for purchase due to abuse by young people.
The average dose / tablet in a cough product is 20mg/tab.
I don't advocate you take more than that/per dose. Anything higher becomes dangerous and requires medical supervision.
Dextromethorphan has been used in studies for post operative pain control. But Nide here, was offered it once and it did NOT work for him.
It will do nothing for muscle spasms that I know of.
So if you try it don't exceed the directions on the package that you purchase!
