Pseudoephedrine hydrochloride is a decongestant drug often used in combination with other drugs for colds and flu and for hay fever. It belongs to the chemical class of drugs called amphetamines, which may cause excitation or wakefulness. It is known by different trade names in different countries, according to manufacturer. Depending on the amount of pseudoephedrine hydrochloride in each product and the country in which it is obtained, it may be available over the counter or by prescription only.

Nasal congestion or stuffiness, be it acutely during a cold or flu, or more chronically with hay fever or allergic rhinitis, is caused by the blood vessels of the nose dilating. Pseudoephedrine hydrochloride is a sympathomimetic drug. This means that it mimics the body's sympathetic nervous system. In the case of pseudoephedrine hydrochloride, it causes vasoconstriction of the blood vessels in the nose, which relieves nasal congestion.

Numerous single-drug and combination preparations are available. Pseudoephedrine hydrochloride alone may be used as a sinus decongestant. Use of pseudoephedrine hydrochloride-containing preparations is usually just for a short period. Due to the amphetamine-like properties of the drug, it may have abuse potential. Some countries have rescheduled the drug so that it is no longer available over the counter due to the illicit manufacture of methamphetamines using pseudoephedrine-containing products.
