Patient leaflet - Latanoprost + Timolol 50 micrograms / ml + 5 mg / ml eye drops solution

1. What Latanoprost/Timolol is and what it is used for

Latanoprost/Timolol contains two medicines: latanoprost and timolol. Latanoprost belongs to a group of medicines known as prostaglandin analogues. Timolol belongs to a group of medicines known as beta-blockers. Latanoprost works by increasing the natural outflow of fluid from the eye into the bloodstream. Timolol works by slowing the formation of fluid in the eye.

Latanoprost/Timolol is used to reduce the pressure in your eye if you have conditions known as open angle glaucoma or ocular hypertension. Both these conditions are linked to an increase in the pressure within your eye, eventually affecting your eyesight. Your doctor will usually prescribe you Latanoprost/Timolol when other medicines have not worked adequately.

2. What you need to know before you use Latanoprost/Timolol

Latanoprost/Timolol can be used in adult men and women (including the elderly), but is not recommended for use if you are less than 18 years of age.

Do not use Latanoprost/Timolol

  • if you are allergic (hypersensitive) to either of the medicines in Latanoprost/Timolol (latanoprost or timolol), beta-blockers, or any of the other ingredients of Latanoprost/Timolol (listed in section 6)
  • if you have now or have had in past respiratory problems such as asthma, severe chronic obstructive bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing and/or long-standing cough)
  • if you have serious heart problems or heart rhythm disorders

Warnings and precautions

Talk to your doctor or pharmacist before using Latanoprost/Timolol if you have now or have had in the past:

  • coronary heart disease – symptoms can include chest pain or tightness, breathlessness or choking, heart failure, low blood pressure (hypotension)
  • disturbances of heart rate such as slow heart beat (bradycardia)
  • breathing problems, asthma or chronic obstructive pulmonary disease (lung disease which may cause wheeziness, difficulty in breathing and/or long standing cough)
  • poor blood circulation disease (peripheral arterial disease such as Raynaud’s disease or Raynaud’s syndrome)
  • diabetes as timolol may mask signs and symptoms of low blood sugar
  • overactivity of the thyroid gland as timolol may mask signs and symptoms
  • you are about to have any kind of eye surgery (including cataract surgery) or have had any kind of eye surgery in the past
  • you suffer from eye problems (such as eye pain, eye irritation, eye inflammation or blurred vision)
  • you know that you suffer from dry eyes
  • you wear contact lenses. You can still use Latanoprost/Timolol but follow the instructions for contact lens wearers in section 3
  • you know that you suffer from angina (particularly a type known as Prinzmetal angina)
  • you know that you suffer from severe allergic reactions that would usually require hospital treatment
  • you have suffered or are currently suffering from an viral infection of the eye caused by the herpes simplex virus (HSV)

Tell your doctor before you have an operation that you are using Latanoprost/Timolol as timolol may change effects of some medicines used during anaesthesia.

Other medicines and Latanoprost/Timolol

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including using eye drops and medicines obtained without a prescription.

Latanoprost/Timolol can affect or be affected by other medicines you are using, including other eye drops for the treatment of glaucoma. Tell your doctor if you are using or intend to use medicines to lower blood pressure, heart medicine or medicines to treat diabetes.

In particular, speak to your doctor or pharmacist if you know that you are taking any of the following types of medicine:

  • Prostaglandins, prostaglandin analogues or prostaglandin derivates
  • Beta-blockers
  • Epinephrine
  • Drugs used to treat high blood pressure such as oral calcium channel blockers, guanethidine, antiarrythmics, digitalis glycosides or parasympathomimetics
  • Quinidine (used to treat heart conditions and some types of malaria)
  • Antidepressants known as fluoxetine and paroxetine

Latanoprost/Timolol with food and drink

Normal meals, food or drink have no effect on when or how you should use Latanoprost/Timolol.

Pregnancy, breast-feeding and fertility

Pregnancy

Do not use Latanoprost Timolol if you are pregnant unless your doctor considers it necessary. Tell your doctor immediately if you are pregnant, think you are pregnant or are planning to become pregnant.

Breast-feeding

Do not use Latanoprost Timolol if you are breast-feeding. Latanoprost Timolol may get into your milk. Ask your doctor for advice before taking any medicine during breast-feeding.

Fertility

Latanoprost and timolol have been found to have no effect on male or female fertility in animal studies.

Driving and using machines

When you use Latanoprost/Timolol your vision may become blurred for a short time. If this happens to you, do not drive or use any tools or machines until your vision becomes clear again.

Latanoprost/Timolol contains benzalkonium chloride and phosphate buffers

This medicine contains 0.2 mg benzalkonium chloride in each millilitre.

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.

Benzalkonium chloride may also cause eye irritation, especially if you have dry eyes or disorders of the cornea (the clear layer at the front of the eye). If you feel abnormal eye sensation, stinging or pain in the eye after using this medicine, talk to your doctor.

This medicine contains 6.3 mg phosphates in each millilitre which is equivalent to 0.2 mg per drop.

If you suffer from severe damage to the clear layer at the front of the eye (the cornea), phosphates may cause in very rare cases cloudy patches on the cornea due to calcium build-up during treatment.

3. How to use Latanoprost/Timolol

Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose for adults (including the elderly) is one drop once a day in the affected eye(s).

Do not use Latanoprost/Timolol more than once a day, because the effectiveness of the treatment can be reduced if you administer it more often.

Use Latanoprost/Timolol as instructed by your doctor until your doctor tells you to stop.

Your doctor may want you to have extra checks on your heart and circulation if you use Latanoprost/Timolol.

Contact lens wearers

If you wear contact lenses, you should remove them before using Latanoprost/Timolol. After using Latanoprost/Timolol you should wait 15 minutes before putting your contact lenses back in.

Instructions for use

  1. 1. Wash your hands and sit or stand comfortably.
  2. 2.

    Twist off the outer cap (which can be thrown away).

    Figure 1

  1. 3.

    Unscrew the protective inner cap. The protective cap should be retained.

    Figure 2

  1. 4. Use your finger to gently pull down the lower eyelid of your affected eye.
  2. 5. Place the tip of the bottle close to, but not touching your eye.
  3. 6. Squeeze the bottle gently so that only one drop goes into your eye, then release the lower eyelid.
  1. 7.

    After using Latanoprost/Timolol, press a finger into the corner of your eye, by the nose (figure 4) for 2 minutes. This helps to stop latanoprost + timolol getting into the rest of the body.

    Figure 3

    Figure 4

  2. 8. Repeat in your other eye if your doctor has told you to do this.
  3. 9. Put the protective inner cap back on the bottle.

If you use Latanoprost/Timolol with other eye drops

Wait at least 5 minutes between using Latanoprost/Timolol and using the other eye drops.

If you use more Latanoprost/Timolol than you should

If you put too many drops in your eye you may experience some minor irritation in your eye and your eyes may water and turn red. This should pass but if you are worried contact your doctor for advice.

If you swallow Latanoprost/Timolol

If you swallow Latanoprost/Timolol accidentally you should contact your doctor for advice. If you swallow a lot of Latanoprost/Timolol you may feel sick, have stomach pains, feel tired, flushed and dizzy and start to sweat.

If you forget to use Latanoprost/Timolol

Carry on with the usual dosage at the usual time. Do not use a double dose to make up to the dose you have forgotten. If you are unsure about anything talk to your doctor or pharmacist.

4. Possible Side Effects

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

You can usually carry on using the drops, unless the effects are serious. If you're worried, talk to a doctor or pharmacist. Do not stop using Latanoprost/Timolol without speaking to your doctor.

Listed below are the known side effects of using Latanoprost/Timolol. The most important side-effect is the possibility of a gradual, permanent change in your eye colour. It is also possible that Latanoprost/Timolol might cause serious changes in the way your heart works. If you notice changes in your heart rate or heart function you should speak to a doctor and tell them you have been using Latanoprost/Timolol.

The following are known side effects of using Latanoprost/Timolol:

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

  • A gradual change in your eye colour by increasing the amount of brown pigment in the coloured part of the eye known as the iris. If you have mixed-colour eyes (blue-brown, grey-brown, yellow-brown or green-brown) you are more likely to see this change than if you have eyes of one colour (blue, grey, green or brown eyes). Any changes in your eye colour may take years to develop. The colour change may be permanent and may be more noticeable if you use Latanoprost/Timolol in only one eye. There appears to be no problems associated with the change in eye colour. The eye colour change does not continue after Latanoprost/Timolol treatment is stopped.

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

  • Eye irritation (a feeling of burning, grittiness, itching, stinging or the sensation of a foreign body in the eye) and eye pain.

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

  • Headache
  • Redness of the eye, eye infection (conjunctivitis), blurred vision, watery eyes, inflammation of the eyelids, irritation or disruption of the surface of the eye
  • Skin rashes or itching (pruritus)

Other side effects

Like other medicines used in the eyes, Latanoprost/Timolol (latanoprost and timolol) is absorbed into the blood. The incidence of side effects after using eye drops is lower than when medicines are, for example, taken by mouth or injected.

Although not seen with Latanoprost/Timolol, the following additional side effects have been seen with the medicines in Latanoprost/Timolol (latanoprost and timolol) and therefore might occur when you use Latanoprost/Timolol. The listed side effects include reactions seen within the class of beta-blockers (e.g. timolol) when used for treating eye conditions

  • Nausea, vomiting (Uncommon).
  • Developing a viral infection of the eye caused by the herpes simplex virus (HSV).
  • Generalized allergic reactions including swelling beneath the skin that can occur in areas such as the face and limbs and can obstruct the airway which may cause difficulty swallowing or breathing, hives or itchy rash, localized and generalized rash, itchiness, severe sudden life-threatening allergic reaction.

  • Signs and symptoms of eye irritation (e.g. burning, stinging, itching, tearing, redness), inflammation of the eyelid, inflammation in the cornea, blurred vision and detachment of the layer below the retina that contains blood vessels following filtration surgery which may cause visual disturbances, decreased corneal sensitivity, dry eyes, corneal erosion (damage to the front layer of the eyeball), drooping of the upper eyelid (making the eye stay half closed), double vision.
  • Darkening of the skin around the eyes, changes to the eyelashes and fine hairs around the eye (increased number, length, thickness and darkening), changes to the direction of eyelash growth, swelling around the eye, swelling of the coloured part of the eye (iritis/uveitis), scarring of the surface of the eye.
  • Whistling/ringing in the ears (tinnitus).
  • Angina, worsening of angina in patients who already have heart disease.
  • Slow heart rate, chest pain, palpitations (awareness of heart rhythm), oedema (fluid build up), changes in the rhythm or speed of the heartbeat, congestive heart failure (heart disease with shortness of breath and swelling of the feet and legs due to fluid build up), a type of heart rhythm disorder, heart attack, heart failure.
  • Low blood pressure, poor blood circulation which makes the fingers and toes numb and pale, cold hands and feet.
  • Shortness of breath, constriction of the airways in the lungs (predominantly in patients with pre-existing disease), difficulty breathing, cough, asthma, worsening of asthma.
  • Taste disturbances, indigestion, diarrhoea, dry mouth, abdominal pain.
  • Hair loss, skin rash with white silvery coloured appearance (psoriasiform rash) or worsening of psoriasis, skin rash.
  • Joint pain, muscle pain not caused by exercise, muscle weakness, tiredness.
