The National Mail Voter Registration Form can be used to register U.S. citizens to vote, to update registration information due to a change of name, make a change of address or to register with a political party.
It is distributed by Reckitt Benckiser in two strengths: Mucinex DM has 30 milligrams of dextromethorphan and 600 mg of guaifenesin; Mucinex DM Maximum Strength has 60 mg of dextromethorphan and 1200 mg of guaifenesin. Tablets are formulated as extended release, which are meant to work for 12 hours.
Mucinex 600mg has only guaifenesin in it, but is an extended release tablet. If crushed up, a person will get a big dose at the time the tablet is taken, but its effects will likely wear off before the 12 hours is up.
