Do you need to be 18 to buy bronkaid from walgreens because it contains ephedrine sulfate?

Probably: ephedrine, (ephedrine sulfate) like pseudo-ephedrine (Sudafed), can be used in the manufacture of methamphetamine, so it requires that you have ID and sign for it, and generally have to be over the age of 18, and the amounts you can get will be limited. Ephedrine (ephedrine sulfate) itself was removed from most medications and is limited to low dose preparations because of its propensity to cause high blood pressure and rapid pulse.
