Do not take if you are suffering from serious eye disease or have had previous eye surgery.

Do not use while taking monoamine oxidase inhibitors or within 14 days of stopping this medication (see section 4.5).

Not to be used in children younger than 12 years of age.

This product must not be administered while soft (hydrophilic) contact lenses are worn (see section 4.4). Soft contact lenses must be removed prior to use and reinserted after a minimum of 15 minutes.

4.4 Special warnings and precautions for use

Benzalkonium chloride may be absorbed by soft contact lenses and may change the colour of the contact lenses. You should remove contact lenses before using this medicine and put them back 15 minutes afterwards (see section 4.3).

If you are being treated for high blood pressure, depression, heart disease, arteriosclerosis, diabetes or increased thyroid activity consult your doctor before using the drops as naphazoline may exacerbate vasoconstriction. For the same reason this product should not be used as a long term ocular irrigant.

Discard any eye drops remaining 28 days after opening the container.

Continued use of this product may increase redness of the eye.

Use of naphazoline in the eye may liberate pigment granules from the iris, especially when given in high doses to elderly patients.

Benzalkonium chloride has been reported to cause eye irritation, symptoms of dry eyes and may affect the tear film and corneal surface. Should be used with caution in dry eye patients and in patients where the cornea may be compromised. Patients should be monitored in case of prolonged use.

If you experience eye pain, changes in vision or continued redness of the eye, or if the condition worsens or persists for more than 24 hours consult a doctor.

If the solution changes colour or becomes cloudy do not use.

4.5 Interaction with other medicinal products and other forms of interaction

May interact with other topically applied autonomic drugs used in the treatment of glaucoma. May interact with monoamine oxidase inhibitors and should not be used by patients receiving such treatment or within 14 days of ceasing therapy. May reverse the antihypertensive action of drugs used in the treatment of hypertension. There may be an increased risk of arrhythmias in patients receiving cardiac glycosides, quinidine or tricyclic antidepressants.

4.6 Fertility, pregnancy and lactation


Although the safety of Optrex Red Eyes Eye Drops during pregnancy has not been established, it is unlikely that sufficient of the active ingredients will reach the foetus to be harmful.

Breast Feeding

Although the safety of Optrex Red Eyes Eye Drops during lactation has not been established, it is unlikely that sufficient of the active ingredients will reach the breast-fed infant to be harmful.

Reporting of Suspected Adverse Reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose


If applied in excessive quantities to the eye, it may give rise to irritation and stinging.

Excessive or long-term use of this product may result in allergic conjunctivitis, allergic blepharitis or rebound conjunctival hyperaemia. Prolonged use may also lead to epithelial xerosis which can exacerbate symptoms of irritation, pain and dryness experienced in allergic conjunctivitis.

Indiscriminate use of decongestants, such as naphazoline, in an irritated eye can induce papillary dilation and precipitate angle-closure glaucoma in eyes that have narrow anterior chamber angles.

Overdosage by mouth may cause nausea, headache, depression of the central nervous system with marked reduction of body temperature and symptoms of bradycardia, sweating, drowsiness and coma, particularly in children. In addition, may cause hypertension followed by rebound hypotension.

There are no or limited data on overdose of topical hamamelis water, but risks are negligible.


Treatment of adverse effects should be symptomatic and supportive.
