# Benzalkonium Chloride 0.01% w/v + Timolol Maleate 0.5% ## SHORT DESCRIPTION Benzalkonium Chloride 0.01% w/v + Timolol Maleate 0.5% is an **ophthalmic eye-drop preparation** used to reduce increased pressure inside the eye. It is commonly prescribed for the management of **glaucoma and ocular hypertension**. **Timolol** is the active medicine that lowers intraocular pressure, while **benzalkonium chloride** is commonly used as a preservative in ophthalmic formulations. ## KEY BENEFITS * Helps lower **intraocular pressure (IOP)** * Supports the management of **glaucoma** * Helps control elevated eye pressure in ocular hypertension * May reduce the risk of pressure-related optic-nerve damage * Provides convenient topical treatment for eye-pressure control * May be used alone or alongside other glaucoma medicines when prescribed ## USES / INDICATIONS This ophthalmic preparation may be prescribed for: * **Open-angle glaucoma** * **Ocular hypertension** * Elevated intraocular pressure requiring treatment * Long-term management of eye pressure to help protect the optic nerve It is not intended to treat eye infections. ## HOW IT WORKS ### Timolol Maleate Timolol is a **non-selective beta-adrenergic receptor blocker**. When applied to the eye, it reduces the production of aqueous humor, the fluid inside the eye. This lowers intraocular pressure and helps reduce the risk of progressive optic-nerve damage associated with glaucoma. ### Benzalkonium Chloride Benzalkonium chloride is primarily included as a **preservative** to help prevent microbial contamination of the eye-drop solution. It is not the component responsible for lowering eye pressure. ## DOSAGE & ADMINISTRATION * Use exactly as prescribed by your ophthalmologist. * A commonly used adult regimen for timolol ophthalmic solution 0.5% is **1 drop in the affected eye(s) twice daily**, but the prescribed dose may vary. * Wash your hands before using the eye drops. * Tilt your head back and gently pull down the lower eyelid. * Instill the prescribed number of drops into the eye. * Avoid touching the dropper tip to the eye, eyelids or other surfaces. * Close the eye gently after application. * Gently press the inner corner of the eye near the nose for about **1 minute** if instructed, to reduce systemic absorption. * If using other eye drops, generally leave an interval of at least **5–10 minutes** between different ophthalmic medicines unless your doctor advises otherwise. * Do not discontinue treatment suddenly without medical advice. ### Contact Lenses Benzalkonium chloride may be absorbed by soft contact lenses and can irritate the eye. Remove contact lenses before application and follow the product instructions regarding when they can be reinserted. ### Missed Dose Apply the missed dose when remembered unless it is almost time for the next dose. Do not use extra drops to compensate. ## SIDE EFFECTS Common side effects may include: * Eye irritation * Burning or stinging * Dry eyes * Watery eyes * Blurred vision * Eye redness * Headache * Fatigue * Dizziness Because timolol can be absorbed systemically, some people may also experience: * Slow heartbeat * Low blood pressure * Shortness of breath * Tiredness ### Serious Side Effects Seek urgent medical attention if you experience: * Difficulty breathing or wheezing * Very slow heartbeat * Fainting * Severe dizziness * Chest pain * Severe allergic reaction * Significant swelling of the face, lips or throat ## PRECAUTIONS & WARNINGS * **For ophthalmic use only.** * Do not swallow the eye drops. * Timolol can be systemically absorbed and may affect the **heart and lungs**. * Tell your doctor if you have asthma, chronic obstructive pulmonary disease (COPD) or other breathing problems. * Inform your doctor if you have a slow heartbeat, heart block, heart failure or other cardiovascular disease. * Tell your doctor if you have diabetes, as beta-blockers may mask some symptoms of low blood sugar. * Use cautiously if you have peripheral vascular disease or circulation problems. * Tell your doctor if you have thyroid disease. * Inform your doctor before surgery or anesthesia because timolol may affect heart rate and blood pressure. * Benzalkonium chloride may cause eye irritation, particularly with prolonged use. * Do not allow the dropper tip to touch the eye or other surfaces. * Do not stop timolol suddenly unless instructed by your doctor. * Regular eye examinations are important during treatment. * Keep out of reach of children. ## DRUG INTERACTIONS Timolol eye drops can interact with medicines even though they are administered topically. Important interactions include: * **Other beta-blockers** — may increase beta-blocking effects and cause excessive slowing of the heart or low blood pressure. * **Calcium-channel blockers** such as verapamil or diltiazem — may increase the risk of slow heartbeat, conduction problems or low blood pressure. * **Digoxin** — may increase the risk of bradycardia or conduction abnormalities. * **Reserpine and other medicines affecting catecholamines** — may increase the risk of low blood pressure or slow heartbeat. * **Other medicines that lower blood pressure** — may enhance hypotensive effects. * **Insulin and other antidiabetic medicines** — timolol may mask certain warning symptoms of hypoglycemia. * **Certain antidepressants or medicines affecting CYP2D6** — may potentially increase systemic beta-blocking effects. Tell your ophthalmologist and pharmacist about all prescription medicines, over-the-counter medicines, vitamins and herbal supplements you use. ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep the bottle tightly closed when not in use. * Store at the recommended temperature. * Protect from excessive heat, moisture and direct sunlight. * Do not touch the dropper tip. * Do not use the solution if it becomes discolored, cloudy or contaminated. * Discard the bottle according to the manufacturer's instructions after opening. * Keep out of reach of children. * Do not use after the expiry date. ## PRESCRIPTION STATUS **Prescription medicine.** Timolol ophthalmic preparations should be used under the supervision of an ophthalmologist or qualified healthcare professional.
