Most people don't realize that a single drop of Combigan twice a day can keep eye pressure at safe levels and the whole routine is actually super simple. Below you'll get the exact Combigan dosage, the right strength of the eye drops, how to apply them without a fuss, and the key safety tips you need to know before you start.
Ready to take control of your glaucoma or ocular hypertension? Let's dive straight in, skip the fluff, and give you the clear, friendly guidance you deserve.
What Is Combigan
Active ingredients & form
Combigan is an ophthalmic solution that combines two proven eyepressurelowering agents: brimonidine tartrate (0.2%) and timolol maleate (0.5%). The bottle holds a clear liquid you apply directly onto the surface of the eye.
Why it's prescribed
Eye doctors prescribe Combigan for primary openangle glaucoma and ocular hypertension essentially when the pressure inside your eye is too high and could damage the optic nerve. The brimonidine portion relaxes fluiddraining vessels, while timolol reduces fluid production, giving a onetwo punch for pressure control.
Mechanism of action (in plain English)
Think of your eye as a small balloon. Too much fluid makes it swell, squeezing the nerves inside. Timolol tells the eye to "make less fluid," and brimonidine says "let the fluid out faster." Together they keep the balloon at a comfortable size.
Standard Combigan Dosage
Adult dosage (the core answer)
Combigan dosage for most adults is straightforward: one drop in each affected eye twice daily, about 12hours apart. That's it no complicated calculations.
Pediatric & specialpopulation dosing
- Children under 12: Generally not recommended unless a specialist decides otherwise.
- Kidney or liver impairment: Your doctor may lower the dose or monitor you more closely.
- Elderly patients: Often the same adult dose, but watch for systemic side effects like a slower heartbeat.
How to adjust if you miss a dose
If you realize you missed a dose, take it as soon as you rememberunless the next scheduled dose is less than four hours away. In that case, just skip the missed one and get back on the regular schedule. Consistency is key, but a single slipup won't ruin your treatment.
How to Use Combigan
Preparation
Wash your hands, give the bottle a gentle shake, and make sure the tip stays clean. If the bottle has been open for more than 30days, toss itfresh drops work best.
Application technique
- Tilt your head back slightly.
- Pull down the lower eyelid to create a small pocket.
- Press the bottle to squeeze out one drop into that pocket.
- Close your eye gently for about a minute. Don't rubit can push the drop out.
Postapplication tips
Press the inner corner of your eye (the nasolacrimal duct) for 30seconds. This "punctal occlusion" keeps the medication from draining into your bloodstream, reducing the chance of systemic side effects.

Combigan Strength & Formulations
Strength comparison
| Product | Timolol | Brimonidine | Notes |
|---|---|---|---|
| Combigan | 0.5% | 0.2% | Standard combo |

Generic vs. brand
The generic version contains the exact same active ingredients and strength as the brandname bottle. Insurance often prefers the generic because it's cheaper, but both are FDAapproved as bioequivalent.
When a doctor might change the strength
If your intraocular pressure (IOP) stays high despite using Combigan as directed, the eyecare professional may add another medication, increase frequency, or switch you to a different combination drop.
Combigan Safety Profile
Common ocular side effects
- Transient redness or burning sensation
- Occasional itching
- Blurred vision for a few minutes after application
Systemic side effects (because of timolol)
Timolol is a betablocker, so it can affect the whole body. Watch for a slower heart rate, lower blood pressure, or shortness of breath, especially if you have asthma.
When to stop and call your doctor
- Severe eye pain or sudden vision loss
- Allergic reaction swelling, rash, or intense itching
- Persistent cough or wheezing
- Any signs of heart palpitations or dizziness
Sideeffects quickscan
| Effect | Frequency | Action |
|---|---|---|
| Redness | Common | Usually resolves |
| Burning | Common | Use punctal occlusion |
| Bradycardia | Rare | Contact doctor |
| Bronchospasm | Rare | Stop immediately |
Combigan Drug Interactions
Topical interactions
If you're using another eye drop (like artificial tears or prostaglandin analogs), wait at least five minutes between each drop. This gives each medication time to be absorbed properly.
Systemic interactions
Because timolol circulates systemically, it can interact with other betablockers (e.g., propranolol) and certain antidepressants that affect the CYP2D6 enzyme. If you're on asthma inhalers, discuss alternatives with your doctor.
Special warnings
- Pregnancy & lactation: Limited data; talk with your OBGYN before starting.
- Severe sinus node dysfunction: Combigan is contraindicated.
- Allergy to brimonidine or timolol: Do not use.
Real Patient Stories
Case study 1 "From doublevision to steady sight"
Jenny, 58, was diagnosed with primary openangle glaucoma three years ago. At first, she missed a few doses because the bottle looked intimidating. After learning the simple twodrop routine and using the punctalocclusion trick, her eye pressure dropped from 28mmHg to a stable 16mmHg. "It only takes 30seconds every morning and night," she says, "and I feel in control again."
Case study 2 Managing side effects
Mark, 70, experienced a persistent burning sensation after each drop. His ophthalmologist suggested applying a cool compress for a minute before the drop and using the punctal occlusion method. The discomfort faded within a week, letting him stay on the medication without interruptions.
Combigan vs. Other Eye Drops
Efficacy
Clinical trials show Combigan lowers IOP by an average of 24%comparable to many singleagent drops but with the convenience of a single bottle.
Safety
Sideeffect rates are similar to timolol alone, but the added brimonidine may increase mild ocular discomfort. Overall, the safety profile is considered favorable for most patients.
Cost & insurance
The generic version typically costs $30$40 per bottle, while brandname Combigan can be $70$90. Many insurers cover the generic, making it a budgetfriendly option.
Final Bottom Line
Here's the short version: use one drop of Combigan in each eye twice a day, keep a fiveminute gap if you're on other eye drops, and watch out for any unusual heart or breathing symptoms. Stick to the proper techniquetilt, pull, drop, press, and wait a minuteand you'll give your eyes the best chance to stay healthy.
If any of the redflag signs (severe pain, vision changes, persistent cough, or allergic reactions) appear, call your eye doctor right away. And remember, the best treatment plan is one you understand and feel comfortable with.
