pseudoephedrine

Pseudoephedrine is a medication commonly used as a decongestant to relieve nasal stuffiness caused by colds, allergies, or sinus infections. It works by narrowing the blood vessels in the nasal passages, reducing swelling and congestion. While effective, it can also be used illegally to manufacture methamphetamine, which is why its sale and purchase are regulated in many countries. Pseudoephedrine is typically found in pill form and should be used according to medical guidance to avoid side effects. It provides quick relief but should be used with caution, especially for individuals with certain health conditions like high blood pressure.
