really? they dont add additives or anything? I have a bottle of just dxm, but the generic tussin brand from riteaid. So you think it should hit me just like normal robitussin?
The active chemical is still Dextromethophan, it will give you the exact same effect. The thing you have to watch out for is if there are other actives such as guaifinesin.
Please make sure DXM is the only active before consuming.
