Pseudoephedrine is an ephedrine analog (that means it's like a "relative" to ephedrine). It's made in a lab and often sold over-the-counter to supposedly help coughs, colds, allergies, and weight loss.
Like ephedrine, most drug stores now keep pseudoephedrine behind the counter. Because it can also be used to make "meth" it is sold in limited quantities. Anyone who wants to buy some needs to show identification and sign for it at the pharmacy.
Pseudoephedrine’s side effects are similar to those of ephedrine...BUT the DANGERS are INCREASED with people unknowingly take too much.
How can that happen?
Someone could take:
Cold, cough, sinus, or allergy medicine
Diet pills or "pep" pills
ANY combination of the above, including caffeine!!
AND...the dangers range from stomachaches to D-E-A-T-H.
(See dangers & risks for ephedrine.)
Bottom Line:
Just because a product is labeled "natural" or "herbal" does NOT guarantee that it is safe. The FDA urgers people to talk with their doctors before using ANY herbal or dietary supplements.
