Description
Overview
How do Optrex Bloodshot Eye Drops (10ml) reduce redness? Optrex Bloodshot Eye Drops contain two distinct active ingredients that work together to restore the normal appearance of the eye. The primary active agent is naphazoline hydrochloride which is a sympathomimetic amine with marked alpha-adrenergic activity. When the eyes become bloodshot the tiny blood vessels or capillaries on the surface of the sclera become dilated and engorged with blood which makes the white of the eye appear red and inflamed. Naphazoline hydrochloride acts as a potent vasoconstrictor. Upon application Optrex Bloodshot Eye Drops stimulate the adrenergic receptors in the vascular smooth muscle causing these dilated blood vessels to constrict or narrow back to their normal diameter. This physical narrowing reduces the volume of blood visible on the surface of the eye and rapidly clears the redness.
The second active ingredient in Optrex Bloodshot Eye Drops is distilled witch hazel which is known pharmacologically as hamamelis water. Witch hazel acts as an astringent. This means Optrex Bloodshot Eye Drops help to shrink and tighten body tissues which provides a cooling and soothing sensation that relieves the feeling of irritation often associated with red eyes.
What causes the symptoms that Optrex Bloodshot Eye Drops (10ml) treat? Optrex Bloodshot Eye Drops are indicated for the temporary relief of redness of the eye due to minor irritation. This redness is often caused by environmental factors such as exposure to smoke, dust, chlorinated swimming pool water or harsh wind. Optrex Bloodshot Eye Drops are also effective for treating eye strain caused by prolonged visual concentration on computer screens or fatigue. By targeting the swollen capillaries Optrex Bloodshot Eye Drops restore the white brightness of the eyes and relieve the accompanying minor discomfort.
Who Is It For
Who are Optrex Bloodshot Eye Drops (10ml) suitable for? Optrex Bloodshot Eye Drops are suitable for adults and children aged 12 years and over. Optrex Bloodshot Eye Drops are specifically designed for individuals suffering from temporary redness who wish to improve the cosmetic appearance of their eyes while soothing irritation. Optrex Bloodshot Eye Drops are not suitable for children under 12 years of age.
Usage Instructions
How to apply Optrex Bloodshot Eye Drops (10ml) correctly? To administer Optrex Bloodshot Eye Drops the user should gently pull down the lower eyelid to form a pocket and tilt the head back. The bottle should be squeezed gently to release the drops without the tip touching the eye or eyelid.
Dosage: The recommended dose is 1 or 2 drops instilled into each affected eye.
Frequency: Optrex Bloodshot Eye Drops can be applied 3 to 4 times daily as required.
How long can Optrex Bloodshot Eye Drops (10ml) be used for? Optrex Bloodshot Eye Drops are intended for occasional use only. Frequent or prolonged use of vasoconstrictors like naphazoline can lead to a condition known as rebound hyperaemia. This occurs when the blood vessels become less responsive to the medication and dilate even further once the effect wears off which results in chronic redness. Therefore Optrex Bloodshot Eye Drops should not be used continuously for more than 24 hours. If symptoms persist longer than this the user should consult an eye care professional.
Warnings
When must Optrex Bloodshot Eye Drops (10ml) not be used? Optrex Bloodshot Eye Drops must not be used by patients suffering from glaucoma or other serious eye diseases.

Contact lenses should be removed prior to application and not reinserted for at least 15 minutes. Optrex Bloodshot Eye Drops must not be used by patients taking monoamine oxidase inhibitors or those with cardiovascular disease including hypertension as the sympathomimetic action can affect blood pressure.

To maintain this sterility the bottle must be discarded 28 days after first opening. Using Optrex Bloodshot Eye Drops after this period increases the risk of bacterial contamination and eye infection.
