Effects that may appear on discontinuing treatment with TIMABAK 0.50% eye drops solution: If the patient interrupts the treatment, the intraocular pressure may increase and impair the vision. Do not discontinue treatment without the doctor's advice.

This medicine should generally not be taken in combination with amiodarone, certain calcium antagonists (bepridil, verapamil, diltiazem) and beta-blockers used to treat heart failure.
Special Precautions
Take special care when using TIMABAK 0.50% eye drops solution: Do not stop treatment suddenly without the doctor's advice.
Do not inject, do not swallow.
Periodic ophthalmological examination should be performed while undergoing this treatment, in particular, to check for drug resistance (loss of drug efficacy during long-term treatment).
Before using this medicine, tell the doctor of any current or previous occurrence of the following medical conditions: coronary heart disease (symptoms may include pain or tightness in the chest, shortness of breath or choking), heart failure or drop in blood pressure (hypotension); heart rhythm disorders, such as a slow pulse; respiratory problems, asthma or chronic pulmonary or bronchial disease with obstruction; poor blood circulation (such as Raynaud's syndrome or disease); diabetes - as timolol may mask the signs and symptoms of hypoglycaemia; an overactive thyroid - as timolol may mask the signs and symptoms; phaeochromocytoma: this will require careful monitoring of the arterial pressure; psoriasis (skin disorder); disease of the cornea.
Contact lens wearers: Avoid wearing contact lenses during treatment due to reduction in lachrymal secretion, linked to beta-blockers in general.
If the patient has to undergo surgery, tell the doctor that the patient is using TIMABAK as timolol may modify the effects of certain drugs used during anaesthesia.
Athletes: The attention of sports professionals is drawn to the fact that this medicinal product contains an active ingredient, which can induce a positive reaction in anti-doping tests.

Side Effects
Like any medicine, TIMABAK 0.50% eye drops solution, is liable to have side effects; however they do not occur systematically in everyone: Provided there are no serious side effects, the patient can usually continue to use the eye drops solution.

As with other eye care medicines, timolol passes into the blood. This can have side effects similar to those observed with beta-blocker agents that are administered intravenously and/or orally.
The frequency of occurrence of side effects after topical eye drops administration is less than that observed when the medicines are taken orally or injected. The listed side effects are those observed in the class of beta-blockers used to treat ocular pathologies: Generalised allergic reactions, particularly swelling under the skin (that can occur in areas such as the face, arms or legs, and which may obstruct the airways, leading to difficulties in breathing or swallowing), hives (or itching), localised or generalised skin eruptions, itching, sudden onset and serious allergic reaction that may cause a life-threatening risk.

Signs and symptoms of ocular irritation (such as a burning sensation, stinging, itching, watery eyes, redness), inflammation of the eyelid, conjunctival redness, conjunctivitis, inflammation of the cornea, blurred vision and detachment of the sub-retinal layer containing blood vessels following filtration surgery that may cause visual disorders, decreased corneal sensitivity, dry eyes, corneal erosion (damage to the upper layer of the eyeball), upper eyelid sagging (leaving the eye half-closed), double vision, visual disorders including changes in the refraction index (sometimes due to discontinued treatment with myotic drops).
Slow pulse, chest pain, palpitations, oedema (accumulation of fluids), changes in heart rhythm and rate, congestive heart failure (heart disease characterised by shortness of breath or swelling of the feet and legs due to accumulation of fluids), a certain type of heart rhythm disorder, heart attack, heart failure.
