Pseudoephedrine is an ingredient in many over-the-counter (OTC) medications, but because it is used to make methamphetamine or crystal meth, many stores have taken the precaution of keeping it behind the counter. Many stores require a driver’s license or other photo identification card and a signature to sell pseudoephedrine-containing drugs. Even when used for legitimate reasons, it can cause some health problems.
