TETRAHYDROZOLINE
About
TETRAHYDROZOLINE belongs to the class of medication called ‘ophthalmic agents’ primarily used for the relief of redness of the eye due to minor eye irritations. Red eyes occur when the vessels in your eye become swollen or irritated.
TETRAHYDROZOLINE contains Tetrahydrozoline, a decongestant that temporarily narrows the blood vessels in the eye. Thus, it helps to relieve the redness of the eye due to minor eye irritations.
Use TETRAHYDROZOLINE as recommended by a health care professional. TETRAHYDROZOLINE is only for use in the eyes. In some cases, you may experience eye pain, irritation, blurred vision, and temporary mydriasis (dilation of the eye pupil). Most of these side effects of TETRAHYDROZOLINE do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
Before taking the TETRAHYDROZOLINE, inform your doctor about all your medical conditions, sensitivities, and medications you are using. TETRAHYDROZOLINE should be avoided if you are allergic to any components in TETRAHYDROZOLINE. If you are pregnant or breastfeeding, do not use the TETRAHYDROZOLINE without consulting a doctor. TETRAHYDROZOLINE may temporarily blur your vision; therefore, wait until your vision is back to normal before using any machinery or driving. You are advised to remove contact lenses before using the TETRAHYDROZOLINE. You are recommended to maintain a time gap of a minimum of 15 minutes between using TETRAHYDROZOLINE and other eye medicines. Stop using and consult the doctor if you feel eye pain, vision changes occur, or redness or irritation of the eye worsens your condition.

Patients Concern
Disease/Condition Glossary
Eye redness: Eye redness refers to a red appearance of the normally white part of the eye. The eye looks red or bloodshot because blood vessels on the eye's surface widen (dilate), bringing extra blood into the eye. Blood vessels can dilate due to Infection, Allergy and Inflammation caused by something other than an infection.
