Tetrahydrozoline

What is Tetrahydrozoline

Tetrahydrozoline is an intranasal and ophthalmic topical vasoconstrictor. It is administered intranasally to treat nasal congestion associated with acute or chronic rhinitis, sinusitis, the common cold, and hay fever and other allergies.

The effectiveness of xylometazoline for relieving nasal congestion and its adverse effect profile are similar to other imidazoline derivatives.

Excessive or prolonged nasal use can cause nasal mucosa irritation; nasal use should generally not exceed 3 consecutive days since some degree of rebound congestion usually results.

Tetrahydrozoline is administered ophthalmically to relieve redness of the eye due to minor ocular irritants. This drug was approved by the FDA in 1954.
