Betaxolol (Betoptic-S) is an eye drop medication. It helps lower pressure within the eye and treats glaucoma in adults. This eye drop is a beta blocker that works by lessening the amount of fluid in the eye. The Betaxolol (Betoptic-S) eye drops are typically used twice a day. Side effects aren't common but can include temporary eye discomfort and watery eyes. Betaxolol (Betoptic-S) can be used by itself or together with other pressure-lowering eye drops.

If you have the suspension version of betaxolol (Betoptic-S), shake the bottle well before you use the eye drops. You don't need to shake the solution version beforehand.
Wash your hands before you put betaxolol (Betoptic-S) in your eyes. Don't let the dropper tip touch the surface of your eye, and don't touch the dropper tip with your hands. This helps keep the tip clean, prevent germs from getting into the medication, and avoid eye infections.
If you wear contact lenses, remove them before each time you use the betaxolol (Betoptic-S) eye drops. Then, wait 15 minutes after you use betaxolol (Betoptic-S) to put your contacts back in your eye. The medication has a preservative in it that can damage contact lenses.
After you place a drop of betaxolol (Betoptic-S) in the eye, close your eye and press one finger to the inner corner of your eye by the nose. Press lightly for 1 minute. This helps make sure your eye absorbs the drop of medication.
If you're using more than one drop of betaxolol (Betoptic-S) or more than one eye drop medication at the same time, wait 5 minutes between each drop.
Your vision might be blurry for a short period of time after you place betaxolol (Betoptic-S) drops in your eye. Be careful driving until your vision clears up.
Tell your optometrist or ophthalmologist if you have any damage or injury to your eye or if you develop an eye infection. Your eye specialist might tell you to stop using betaxolol (Betoptic-S) until your eye gets better. They might recommend that you use a new bottle of medication if you have an eye infection just in case the bottle you're currently using got contaminated.
Store betaxolol (Betoptic-S) at room temperature. Don't use the eye drops after its expiration date because it might not be safe to use.
Betaxolol (Betoptic-S) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Diabetes
Beta blockers can cause people with diabetes (high blood sugar) to not notice symptoms of low blood sugar, except for sweating and dizziness. Very small amounts of betaxolol (Betoptic-S) might get absorbed into your bloodstream, so this isn't common with beta blocker eye drops. Talk to your primary care provider to see whether you should check your blood sugar more often if you have diabetes and you're using betaxolol (Betoptic-S).
Beta blockers can cause people with an overactive thyroid to not recognize the signs of hyperthyroidism, such as a fast heart rate. It's possible for some betaxolol (Betoptic-S) to get absorbed into your bloodstream and cause this effect. Make sure your optometrist or ophthalmologist knows whether you have thyroid problems before you start treatment with betaxolol (Betoptic-S).
It's possible for beta blockers like betaxolol (Betoptic-S) to worsen symptoms like muscle weakness in people who have myasthenia gravis. Watch out for worsening symptoms if you have myasthenia gravis and let your care team know if this happens to you.
Risk factors: History of asthma | History of chronic obstructive pulmonary disease (COPD) | History of other lung conditions
Beta blocker medications like betaxolol (Betoptic-S) are usually not recommended for people with lung conditions, like asthma and COPD. Beta blockers can cause trouble breathing by making the airways to become narrower. Make sure your healthcare team knows if you have or have ever had any lung problems or conditions before you start using betaxolol (Betoptic-S) to check whether it's safe for you.
Risk factors: History of congestive heart failure | History of heart block
It's possible for betaxolol (Betoptic-S) to have a small effect on heart rate and blood pressure. Tell your care team about your medical history, especially if you've had heart failure or heart block. Changes in heart rate and blood pressure can affect these heart conditions. Talk to your primary care provider if you notice swelling in your feet or ankles, a fast or irregular pulse, or shortness of breath when you lie down or exercise. These might be signs of heart problems.
