1. What Tanolux is and what it is used for

Latanoprost belongs to a group of medicines known as prostaglandin analogues. It works by increasing the natural outflow of fluid from the inside of the eye into the bloodstream.

Latanoprost is used to treat conditions known as open-angle glaucoma and ocular hypertensionin adults. Both conditions are related to an increase in pressure within the eye, which can eventually affect vision.

Latanoprost is also used to treat increased pressure within the eye and glaucoma in children and babies of all ages.

2. What you need to know before you start using Tanolux

Latanoprost can be used in adult men and women (including the elderly) and in children from birth to 18 years of age. Latanoprost has not been investigated in premature infants (less than 36 weeks of gestation).

This medicine contains 6.3 mg/ml of phosphates, which is equivalent to 0.2 mg/drop.

If you have severe damage to the transparent front part of the eye (cornea), phosphates may, in very rare cases, cause cloudy areas in the cornea due to calcium deposits produced during treatment.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

The following are known side effects of using Tanolux:

Very common side effects(may affect more than 1 in 10 people):

  • Gradual change in eye color due to an increase in the amount of brown pigment in the colored part of the eye known as the iris. If you have mixed-color eyes (blue-brown, gray-brown, yellow-brown or green-brown) you are more likely to experience this change than if your eyes are a single color (blue, gray, green or brown). The change in eye color takes years to develop, although it can usually be seen after 8 months of treatment. The change in eye color may be permanent and may be more noticeable if Tanolux is used in only one eye. The change in eye color does not seem to be associated with the development of any problems. The change in eye color does not progress once treatment with Tanolux has been stopped.
  • Redness of the eye.
  • Eye irritation (feeling of stinging, feeling of grit in the eye, itching, pain and feeling of a foreign body in the eye). If you experience severe eye irritation that makes your eyes water excessively or makes you consider stopping treatment, consult your doctor, pharmacist or nurse as soon as possible (within a week). You may need to have your treatment reviewed to ensure you are receiving the right treatment for your condition.
  • Gradual change in the eyelashes of the treated eye and the fine hair around the treated eye, observed in most patients of Japanese origin. These changes include an increase in color (darkening), length, thickness and number of eyelashes.

Common side effects(may affect up to 1 in 10 people):

  • Irritation or erosion of the eye surface, eyelid inflammation (blepharitis), eye pain and sensitivity to light (photophobia), conjunctivitis.

Uncommon side effects(may affect up to 1 in 100 people):

  • Swelling of the eyelids, dry eye, inflammation or irritation of the eye surface (keratitis), blurred vision, inflammation of the colored part of the eye (uveitis), swelling of the retina (macular edema).
  • Skin rash.
  • Chest pain (angina), feeling your heartbeat (palpitations).
  • Asthma, difficulty breathing (dyspnea).
  • Chest pain.
  • Headache, dizziness.
  • Muscle pain, joint pain.
  • Nausea, vomiting.

Rare side effects(may affect up to 1 in 1,000 people):

  • Inflammation of the iris (iritis), symptoms of swelling or injury/damage to the eye surface, swelling around the eye (periorbital edema), misdirected eyelashes or additional row of eyelashes, scarring of the eye surface, accumulation of fluid in the colored part of the eye (iris cyst), sensitivity to light (photophobia).
  • Skin reactions on the eyelids, darkening of the eyelid skin.
  • Worsening of asthma.
  • Severe itching of the skin.
  • Development of a viral eye infection caused by the herpes simplex virus (HSV).

Very rare side effects(may affect up to 1 in 10,000 people):

  • Worsening of angina in patients who also have heart problems, appearance of sunken eyes (greater depth of the eyelid sulcus).

Side effects observed in children at a higher frequency than in adults are runny nose and itchy nose and fever.

In very rare cases, some patients with severe damage to the transparent front part of the eye (cornea) have developed cloudy areas in the cornea due to calcium deposits produced during treatment.
