Timolol Eye Drops: Uses, Dosage & Side Effects in Pakistan

Timolol Eye Drops Uses, Dosage, Side Effects & Price in Pakistan

1. Quick Info (Mukhtasir Maloomat)

2. What is Timolol Eye Drops? (Timolol Eye Drops kya hai)

Timolol Eye Drops (brand: Timoptol / Timoptic) are used in Pakistan on a doctor's prescription for open-angle glaucoma and ocular hypertension. They belong to the Non-selective Beta-Blocker drug class and Timolol Maleate is the active ingredient.

By blocking beta-1 and beta-2 receptors on the ciliary body, it reduces aqueous humour production in the eye — lowering intraocular pressure (IOP) by up to 25–30%. CRITICAL: Although Timolol is applied locally to the eye, it enters the bloodstream and acts as a systemic beta-blocker throughout the body — this is why it is contraindicated in asthma, COPD, and certain cardiac conditions. It is a prescription medicine — do not use without a doctor's advice.

3. Uses (Fayde / Kis kaam aati hai)

• Open-angle Glaucoma
• Ocular Hypertension

4. Who Should Take (Kis ko leni chahiye)

• Adults diagnosed with open-angle glaucoma by an ophthalmologist
• Patients with ocular hypertension at risk of glaucomatous optic nerve damage
• Patients where IOP lowering is needed and asthma, COPD, cardiac contraindications are absent
• Often combined with latanoprost or dorzolamide for additional IOP lowering

5. When NOT to Take (Kab nahi leni chahiye)

• Asthma or COPD — CONTRAINDICATED
• Severe bradycardia — CONTRAINDICATED
• Second- or third-degree heart block — CONTRAINDICATED
• Cardiogenic shock or severe heart failure — CONTRAINDICATED
• Allergy to Timolol or any ingredient
• If the nasolacrimal occlusion technique is not known — learn it from your doctor or pharmacist first

6. Dosage (Kitni leni hai)

• As prescribed — typically one drop of 0.5% solution twice daily

• One drop of 0.5% solution twice daily; 0.25% twice daily may be used initially

• Do not exceed the recommended limit — follow your doctor's instructions

• If you forget a dose, apply it as soon as you remember. If the next dose is close, skip the missed dose. Never double dose.

7. How to Take (Kaise leni hai)

• Immediately after applying the drop, press gently on the inner corner of the eye with a finger for a full 2 minutes — this dramatically reduces systemic absorption — THIS TECHNIQUE IS VERY IMPORTANT

• Place one drop in the lower conjunctival sac of the eye; close the eye and press the inner corner for 2 minutes

• One drop at a time is sufficient — excess drops increase systemic absorption

• If another eye drop is also needed, wait 5 minutes before applying the second drop

8. Best Time (Kab leni chahiye)

• Morning and evening — maintain the same time consistently

• Daily same time

9. Empty Stomach or After Food (Khali pait ya khane ke baad)

• These are eye drops — food has no bearing. The nasolacrimal occlusion technique is essential to reduce systemic absorption.

10. Warnings (Ihtiyat)

• Asthma or COPD — CONTRAINDICATED — systemic beta-blockade can cause bronchospasm, which can be life-threatening
• Severe bradycardia, heart block, cardiogenic shock, severe heart failure — CONTRAINDICATED
• Informing your anaesthetist before surgery is essential — intraoperative bradycardia risk
• Diabetics — hypoglycaemia warning signs (tachycardia) can be masked — silent hypoglycaemia risk
• Combination with systemic beta-blockers — additive bradycardia, heart block risk
• Learn and use the nasolacrimal occlusion technique every time

11. Precautions (Ahm ehtiyaat)

• Below 25°C, keep protected from light
• Discard 4 weeks after opening the bottle (contamination risk)
• Keep out of the reach of children
• Contact lenses — remove lenses before applying drops; they can be reinserted after 15 minutes (benzalkonium chloride preservative)

12. Side Effects (Nuksanat)

• Bradycardia, Hypotension, Fatigue, Stinging/burning on instillation, Dry eye, Impotence, Depression

• Bronchospasm, Severe bradycardia/heart block, Heart failure exacerbation, Masking of hypoglycaemia, Depression/mood changes

13. Drug Interactions (Dawaon ke sath reaction)

• Systemic beta-blockers — additive bradycardia and heart block — avoid combination
• Verapamil or diltiazem (CCBs) — severe bradycardia / heart block — same risk as oral beta-blocker combination
• Adrenaline (epinephrine) — paradoxical hypertension (same as oral beta-blockers)
• Other glaucoma drops (latanoprost, dorzolamide) — usually combined — wait 5 minutes between drops
• Diabetes medications — masking of hypoglycaemia

Heart rate may slow and blood pressure may drop — this can be dangerous.

14. When to See Doctor (Kab doctor ke paas jayein)

• Difficulty breathing or wheeze
• Heart rate becomes very slow or fainting (severe bradycardia)
• Heart failure symptoms worsen
• Depression or significant mood change (central beta-blockade)
• Severe pain, redness, or vision change in the eyes (glaucoma worsening)
