Naphazoline hydrochloride brief introduction:

Naphazoline (in the hydrochloride form) is the common name for 2-(1-naphthylmethyl)-2-imidazoline hydrochloride. It is a sympathomimetic agent with marked alpha adrenergic activity. It is a vasoconstrictor with a rapid action in reducing swelling when applied to mucous membrane. It acts on alpha-receptors in the arterioles of the conjunctiva to produce constriction, resulting in decreased congestion. It is an active ingredient in several over-the-counter formulations including Clear Eyes and Naphcon eye drops.

Warnings and contraindications

A few warnings and contraindications that apply to all naphazoline-containing substances intended for medicinal use are:

Hypersensitivity to naphazoline

Patients taking MAO inhibitors can experience a severe hypertensive crisis if given a sympathomimetic drug such as naphazoline HCl

Use in infants and children can result in central nervous system depression, leading to coma and marked reduction in body temperature

Should be used with caution in patients with severe cardiovascular disease including cardiac arrhythmia and in patients with diabetes, especially those with a tendency toward diabetic ketoacidosis

Drug interactions can occur with anaesthetics that sensitize the myocardium to sympathomimetics (e.g. cyclopropane or halothane cautiously)

Exercise caution when applying prior to use of phenylephrine.

Extended use may cause rhinitis medicamentosa, a condition of rebound nasal congestion.

A possible association with stroke has been suggested.
