COLDAN Eye Drops – For the relief of eye irritation and conjunctival swelling

COLDAN eye drops contain the active ingredient naphazoline hydrochloride, which belongs to the group of vasoconstricting agents. The medicinal product is used for the short-term relief of non-infectious irritation of the conjunctiva, for example caused by dust, smoke, light, drafts, or chemical irritants.

The active ingredient naphazoline constricts the fine blood vessels of the conjunctiva, thereby helping to reduce swelling and redness. At the same time, the formation of eye secretions is reduced.

The effect usually begins within a few minutes of application and lasts for approximately 4 hours.

COLDAN eye drops are suitable for adults as well as children and adolescents from the age of 6. For children between 2 and 6 years of age, use must be exclusively upon medical advice.

Mechanism of action – How do COLDAN eye drops work?

The active ingredient naphazoline hydrochloride contained in COLDAN eye drops belongs to the group of so-called sympathomimetics.

Naphazoline has a vasoconstricting effect on the small blood vessels of the conjunctiva. When eyes are irritated, these blood vessels can dilate, causing the conjunctiva to appear red and potentially swell.

By constricting the blood vessels, blood flow in the superficial conjunctival vessels is temporarily reduced. This allows redness and swelling to subside.

Additionally, naphazoline reduces the formation of eye secretions, which may occur increasingly during conjunctival irritation.

The effect usually begins within a few minutes after application and lasts for approximately 4 hours.

COLDAN eye drops treat the symptoms of non-infectious conjunctival irritation. The active ingredient does not treat an underlying infection.

Areas of application

COLDAN eye drops are used for the short-term symptomatic treatment of irritation of the conjunctiva that is not caused by an infection.

Possible triggers include:

• Dust: Irritation of the conjunctiva due to dust particles in the environment.

• Smoke: Eye redness and swelling due to cigarette smoke or other sources of smoke.

• Light: Irritation of the eyes due to strong light exposure.

• Drafts: Discomfort due to air currents or wind.

• Chemical irritants: Non-infectious irritation due to certain chemical influences.

• Other external environmental influences: Temporary conjunctival irritation accompanied by redness, swelling, or increased secretion.

In case of suspected eye infection, severe eye pain, vision impairment, or severe light sensitivity, a medical examination should be performed before use.

After contact with corrosive chemicals, immediate eye rinsing and urgent medical clarification are required.

Application and dosage

COLDAN eye drops are intended exclusively for use in the eye.

The solution is dropped directly into the conjunctival sac of the affected eye.

Steps for application:

1. Wash your hands thoroughly before application.

2. Open the bottle carefully.

3. Tilt your head slightly backward.

4. Gently pull down the lower eyelid so that a small conjunctival sac is formed.

5. Apply the amount specified in the instructions for use into the conjunctival sac.

6. Avoid direct contact between the dropper pipette and the eye, eyelids, or other surfaces.

7. Close the bottle carefully after use.

The exact number of drops, the frequency of use, and the maximum duration of treatment depend on the information in the current instructions for use or medical instructions.

Excessive or prolonged use of vasoconstricting eye drops can lead to renewed or increased redness of the eyes after the effect wears off.

Children under 2 years: COLDAN eye drops must not be used in this age group.

Children from 2 to 6 years: Use must occur exclusively upon explicit medical instruction.

Children and adolescents from 6 years: Use is possible according to the instructions in the package leaflet.

Notes on specific ingredients

Benzalkonium chloride

COLDAN eye drops contain benzalkonium chloride as a preservative.

Benzalkonium chloride can be absorbed by soft contact lenses and may discolor them. It can also cause eye irritation, especially in sensitive eyes or in the case of corneal changes.

Contact lens wearers should note the relevant information in the instructions for use.

Phosphate buffer

The eye drops contain phosphates. In patients with severe corneal damage, calcium deposits in the cornea have been reported in very rare cases in connection with phosphate-containing eye drops.

• Severe light sensitivity

• Purulent discharge from the eye

• Suspected infectious conjunctivitis

• Symptoms that persist or worsen despite use

Special caution is required for certain eye conditions, especially in cases of increased intraocular pressure or certain forms of glaucoma.

Also, in cases of cardiovascular disease, high blood pressure, hyperthyroidism, or concomitant use of certain medications, use should be clarified in advance with a doctor or pharmacist.

During pregnancy or breastfeeding, medical advice should be sought before use.
