Dexchloropheniramine maleate tablets have 2mg; chlorpheniramine maleate tablets had 4mg. Dex isomer's more potent? Or ploy to sell more tablets?

1 doctor agrees

In brief: Tab difference

hello ~ dex~etc is a totally different substance to chlorphen~etc base.
Each compound in organic chem has completely different properties, by adding free radicals (-H, -OH, -S03,-S04,-NH3,NH4) This is not a scam but dose equivalents. Do not mess with dose advised on label ! Take AS DIRECTED ! ALWAYS !
