6.Contents of the package and additional information

CUSIMOLOL is an eye drop that contains an active ingredient (timolol), which works by reducing the pressure inside the eye (intraocular pressure), whether or not it is associated with glaucoma.

This medication is used to reduce elevated eye pressure in ocular hypertension (increased pressure in the eye) and in chronic open-angle glaucoma (including patients who have undergone cataract extraction surgery).

Do not use CUSIMOLOL

• If you are allergic to timolol, other beta-blockers, or any of the other components of this medication (listed in section 6).
• If you have or have had respiratory problems such as asthma, severe chronic obstructive bronchitis (a serious lung disease that can cause wheezing, difficulty breathing, and/or long-term coughing).
• If you have heart failure, slow heart rate, or heart rhythm disorders (irregular heartbeats).
• If you have severe allergic rhinitis.
• If you have eye corneal alterations.

Warnings and precautions

Consult your doctor or pharmacist before starting to use CUSIMOLOL.

Only use this medication in your eye(s).

Before starting to use this medication, inform your doctor if you have or have had:

• coronary disease (symptoms may include chest tightness or pain, shortness of breath, or choking), heart failure, low blood pressure.
• heart rate alterations such as bradycardia (slow heart rate).
• respiratory problems, asthma, or chronic obstructive pulmonary disease.
• circulatory disease (such as Raynaud's disease or Raynaud's syndrome).
• diabetes, as timolol may mask the signs and symptoms of low blood sugar.
• hyperthyroidism, as timolol may mask the signs and symptoms.
• myasthenia gravis (chronic neuromuscular weakness).
• If you have any severe allergic reaction (skin rash, redness, and itching in the eye) while using this medication, regardless of the cause, adrenaline treatment may not be as effective. Therefore, when receiving any other treatment, inform your doctor that you are using this medication.
• If you have corneal disorders, consult your doctor as this medication may cause eye dryness.

Inform your doctor that you are using this medication before undergoing surgery, as timolol may alter the effects of some medications used during anesthesia.

If you have angle-closure glaucoma, you must use this medication in combination with other medications that close the pupil. You must regularly monitor your eye pressure, especially at the beginning of treatment.

Do not use contact lenses during the administration of this medication (see the section "CUSIMOLOL contains benzalkonium chloride and phosphates").

Children and adolescents

Generally, timolol eye drops should be used with caution in young patients. This medication should be used with extreme caution in newborns, infants, and small children. Immediately discontinue use of this medication if you notice coughing, wheezing, abnormal breathing, or pauses in breathing (apnea). Consult your doctor as soon as possible. A portable apnea monitor may be helpful.

This medication has been studied in babies and children aged 12 days to 5 years with increased eye pressure or diagnosed with glaucoma. For more information, consult your doctor.

Other medications and CUSIMOLOL

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

This medication may affect or be affected by other medications you are using, including other eye drops for glaucoma treatment. Consult your doctor if you are using or plan to use medications to lower blood pressure, heart medications including quinidine (used to treat heart conditions and some types of malaria), medications to treat diabetes, or antidepressants known as fluoxetine and paroxetine.

Consult your doctor if you are being treated for depression, as CUSIMOLOL should not be taken with type IMAO medications used to treat this type of condition.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Do not use this medication if you are pregnant unless your doctor considers it necessary.

Do not use this medication if you are breastfeeding as timolol may pass into breast milk.

Driving and operating machinery

You may notice that your vision becomes blurry after applying the eye drop. In some patients, Cusimolol may also cause hallucinations, dizziness, nervousness, or fatigue. Do not drive or operate machinery until these symptoms have disappeared.

CUSIMOLOL contains benzalkonium chloride and phosphates

This medication contains 0.1 mg of benzalkonium chloride in each ml.

Benzalkonium chloride can be absorbed by soft contact lenses and may alter the color of the lenses. Remove contact lenses before using this medication and wait 15 minutes before reinserting them.

Benzalkonium chloride may cause eye irritation, especially if you have dry eyes or other corneal disorders (transparent layer at the front of the eye). Consult your doctor if you feel a strange sensation, burning, or pain in the eye after using this medication.

This medication contains 9.4 mg of phosphates in each ml.

If you have severe damage to the transparent layer at the front of the eye (cornea), treatment with phosphates, in rare cases, may cause cloudy patches in the cornea due to calcium.

Use in athletes

This medication contains timolol, which may produce a positive result in doping control tests.

Follow exactly the administration instructions of this medication as indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

The recommended dose is:

Use in adults (including elderly patients)

It is recommended to start treatment with the lowest available dose of timolol. If the response is not satisfactory, your doctor may change the dose to 1 drop of CUSIMOLOL 5mg/ml in the affected eye(s) twice a day (morning and evening).

If necessary, your doctor may decide to complement this treatment with other medications that reduce intraocular pressure.

In some patients, the decrease in intraocular pressure in response to timolol treatment may require a period to stabilize, so your doctor may recommend that you monitor your intraocular pressure approximately every 4 weeks. If your doctor considers it appropriate, they may reduce the dose to one drop per day in the affected eye(s).

In the case of this eye drop replacing a previous treatment for your glaucoma or being used in conjunction with other medications, follow exactly the dosage indicated by your doctor.

Your doctor will indicate the duration of your treatment with this medication. Do not discontinue treatment unless your doctor instructs you to do so.

Follow these instructions unless your doctor has given you different ones.

Remember to apply your medication when it is due.

Paediatric population

A detailed medical examination must precede the use of timolol. Your doctor will rigorously evaluate the risks and benefits before considering treatment with timolol. If the benefits outweigh the risks, it is recommended to use the lowest available concentration of active ingredient, once a day. In relation to "use in children", a concentration of 0.1% active ingredient may be sufficient to control intraocular pressure. If this dose is not sufficient to control intraocular pressure, it may be necessary to administer it twice a day with 12-hour intervals. Patients, especially neonates, must be strictly observed for one or two hours after the first dose and closely monitor any side effects that may appear until the operation is performed.

Administration form

This eye drop should only be instilled in one drop per administration.

After using this eye drop, close your eyes as long as possible (e.g.3 – 5 minutes) and press with your finger the edge of your eye next to your nose to prevent this medication from passing into the rest of your body.

Treatment duration:

For a transient treatment in the paediatric population.

Like all medications, this medication may cause side effects, although not everyone will experience them.

The following side effects have been observed with this medication:

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

• Eye effects: blurred vision, pain, irritation, discomfort, and redness of the eye.

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

• Eye effects: corneal erosion (damage to the anterior layer of the eyeball), superficial eye inflammation with or without surface damage, iris inflammation, conjunctival inflammation, eyelid inflammation, reduced vision, light sensitivity, dry eye, increased tear production, eye discharge, eye itching, eyelid crust, eye inflammation, eyelid swelling.

• General effects: asthma, bronchitis, shortness of breath, headache, bad taste, reduced heart rate, fatigue, decreased blood pressure.

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

• Eye effects: double vision, tired eyes, eczema on the eyelids, eyelid redness, eye itching, eyelid swelling, corneal color change.

• General effects: depression, reduced cerebral blood flow, dizziness, migraine, infarction, increased blood pressure, tissue swelling, cold extremities, pulmonary obstructive disease (COPD), bronchial constriction in the lungs, difficulty breathing, cough, wheezing, nasal congestion, stomach discomfort, abdominal discomfort, dry mouth, facial swelling, skin redness, body weakness, chest discomfort.

During post-marketing experience, additional side effects have been reported, the frequency of which is unknown:(cannot be estimated from available data):

• Eye effects: retinal detachment with underlying vascular damage that can cause vision disturbances after filtration surgery, upper eyelid drooping (causing the eye to be half-closed).

• General effects:

• Swelling under the skin that can occur on the face and extremities, and may obstruct airways, causing difficulty swallowing or breathing, allergy.
• Low blood sugar levels.
• Hallucinations, insomnia, memory loss, nightmares.
• Fatigue, syncope, unusual sensations such as tingling.
• Cardiac arrest, type of cardiac rhythm alteration, worsening of congestive heart failure (heart disease with difficulty breathing and swelling of the feet and legs due to fluid accumulation), changes in heart rhythm or frequency, palpitations.
• Raynaud's phenomenon (numbness and coldness in fingers and toes).
• Respiratory disorders.

• Sexual dysfunction and Peyronie's disease (a type of male sexual dysfunction).

Additionally:

In very rare cases, some patients with severely damaged transparent layer of the front part of the eye (cornea) have experienced cloudy areas in the cornea due to calcium accumulation during treatment.

Like other medications administered in the eyes,timolol is absorbed into the bloodstream. This can cause side effects similar to those observed with intravenous and oral beta-blocker medications. The incidence of side effects after topical administration is lower than with medications administered orally or by injection. The adverse reactions described include reactions observed within the class of beta-blocker eye drops when used to treat eye diseases:

• Generalized allergic reactions, urticaria or hives with itching, localized and generalized rash, itching, severe and sudden allergic reaction that may put your life at risk.
• Memory loss.
• Increased signs and symptoms of myasthenia gravis (muscular disorder).
• Decreased corneal sensitivity, dry eyes, double vision.
• Chest pain, edema (fluid accumulation), heart failure.
• Constriction of airways in the lungs (mainly in patients with pre-existing bronchospastic disease).
• Muscle pain not caused by exercise.
• Decreased libido.

Generally, you can continue using the drops unless the effects are severe. If you are concerned, consult your doctor or pharmacist. Do not stop using this medication without consulting your doctor.
