Information About Tetryzoline

Tetryzoline is a sympathomimetic used as an ocular vasoconstrictor and nasal decongestant to relieve red eyes and nasal congestion in Singapore. Available as a 0.05% ophthalmic solution applied two to four times daily or as a nasal spray, it is HSA-registered and available on prescription only in Singapore. Its vasoconstrictive effect provides rapid redness relief but does not address the underlying cause — extended use beyond five days risks rebound redness, and patients with closed-angle glaucoma should avoid tetryzoline-containing eye drops due to mydriasis risk.
