Timolol Eye Drops

• Type: Beta-blocker (used in the eyes)

• Main Use: Lowers intraocular pressure (IOP) in conditions like glaucoma and ocular hypertension.

How It Works

• Timolol blocks beta receptors in the eye’s ciliary body.

• This reduces the production of aqueous humor (the fluid inside the eye).

• Less fluid production leads to lower eye pressure, which helps prevent optic nerve damage and vision loss.

Common Uses

• Open-angle glaucoma (most common type of glaucoma)

• Ocular hypertension (high eye pressure without optic nerve damage)

• Sometimes used along with other glaucoma medications (like prostaglandin analogs, carbonic anhydrase inhibitors) for better pressure control

Advantages

• Very effective at reducing eye pressure

• Works relatively quickly (within a few hours)

• Can be combined with other eye drops when needed

Possible Side Effects

Local (Eye):

• Mild burning or stinging after application

• Eye redness or irritation

• Blurred vision (temporary)

Systemic (Body-wide):

• Slow heart rate (bradycardia)

• Low blood pressure

• Fatigue or dizziness

• May worsen asthma or other breathing problems (because beta-blockers can affect the lungs)

Precautions

• Should be used under medical supervision, especially in people with heart problems, low blood pressure, or asthma.

• Apply using the “punctal occlusion” technique (press gently on the corner of the eye after application) to reduce absorption into the bloodstream and minimize systemic effects.

• Do not stop using suddenly without consulting your doctor — stopping abruptly may cause eye pressure to rise again.

• Inform your doctor about any heart or lung conditions before using.
