Levobunolol
About Levobunolol
Levobunolol is an ophthalmic (eye) drop used to lower high pressure inside the eye. It is commonly prescribed to treat conditions like open-angle glaucoma and ocular hypertension, where fluid buildup can threaten your sight. By reducing this internal pressure, the medication helps protect your optic nerve and preserve your vision.
For this medicine to work effectively, you must apply it consistently and exactly as directed by your doctor. It is typically used once or twice daily, and keeping a regular schedule is key to managing your eye pressure. Along with using Levobunolol, maintaining a healthy lifestyle and getting regular eye checkups will help support your overall eye health.
While using Levobunolol, some people may experience mild, temporary eye irritation or blurred vision immediately after applying the drops. If you notice any serious side effects, such as a very slow heartbeat, dizziness, or breathing difficulties, you must stop using the drops and consult your doctor right away.
Talk to your doctor before starting Levobunolol if you have a history of heart or lung conditions. Do not take this if you have asthma, severe chronic obstructive pulmonary disease (COPD), or a slow, irregular heartbeat, as the medicine can be absorbed into your bloodstream and worsen these conditions.
This medicine may interact with certain oral blood pressure drugs, heart medications, or other eye drops. If you are pregnant, planning to become pregnant, breastfeeding, or are an older adult, consult your healthcare provider to ensure this treatment is safe for you.

Drug Interactions
Drug-Drug Interactions
Some medicines may affect how Levobunolol works or increase the risk of side effects. Tell your doctor about all the medicines you are taking, including:
- Oral beta-blockers: Taking beta-blocker tablets for blood pressure or heart conditions while using Levobunolol eye drops can increase the risk of slow heart rate and low blood pressure.
- Calcium channel blockers and digoxin: Combining these heart medications with Levobunolol can lead to severe disturbances in heart rhythm.
- Other glaucoma eye drops: Using multiple beta-blocker eye drops simultaneously is not recommended as it can cause excessive systemic side effects.
Drug-Disease Interactions
Certain medical conditions may affect how Levobunolol works or increase the risk of side effects. Inform your doctor if you have any of the following conditions before starting treatment.
- Asthma and chronic obstructive pulmonary disease (COPD): This medicine can cause severe airway constriction, which may lead to breathing emergencies in people with these lung conditions.
- Heart conditions: Do not use this medicine if you have heart failure, an extremely slow heart rate, or certain heart blocks, as it can worsen heart function.
- Diabetes: Beta-blocker drops can mask the warning signs of low blood sugar, such as a rapid heart rate. Talk to your doctor if you have diabetes.

Habit Forming
Diet & Lifestyle Advise
- Engage in moderate exercise: Regular, moderate physical activity like walking can help lower eye pressure. Avoid heavy weightlifting or head-down yoga positions, as these can increase pressure.
- Elevate your head: Use an extra pillow to keep your head slightly elevated while sleeping, which may help lower fluid pressure in the eyes overnight.
- Limit caffeine intake: Drinking large amounts of coffee or highly caffeinated beverages can temporarily increase eye pressure. Keep your intake moderate.
- Protect your eyes: Wear sunglasses to guard against UV rays and protective eyewear during sports or home improvement projects to prevent eye injuries.
- Eat a nutrient-rich diet: Focus on foods high in antioxidants, such as leafy green vegetables, berries, and fish rich in omega-3 fatty acids, to support overall nerve health.
Special Advise
You are advised to inform your doctor before any operation that you are using Levobunolol as it may alter the effects of some medicines used during anesthesia.
- Your doctor may monitor eye pressure after 4 weeks of starting treatment with Levobunolol.
- Levobunolol may make it harder to tell if you have signs of an overactive thyroid like a fast heartbeat. So, if you have an overactive thyroid (hyperthyroidism) and have stopped taking Levobunolol all of a sudden, it may be life-threatening.
Patients Concern
Disease/Condition Glossary
Glaucoma: It is an eye condition that causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. If it is not treated in time, it may cause blindness. Usually, there are no symptoms of glaucoma initially except the slow loss of vision gradually. However, some symptoms include visible rainbow-colored circles around bright lights or blurred vision. Rarely, glaucoma can develop suddenly with intense pain in the eye, visual disturbance, or nausea.
Ocular hypertension: It is a condition caused due to poor drainage of aqueous humor (fluid in the eye that maintains normal pressure by its continuous flow). This leads to the building up of excess fluid in the eye, resulting in increased pressure inside the eye without any damage to the optic nerve. If ocular hypertension is not controlled, it may lead to glaucoma.
FAQs
Levobunolol is used to treat increased pressure in the eyes.
Levobunolol contains Levobunolol that works by blocking beta-receptors on the ciliary body (part of the eye that produces aqueous humour) and decreases the secretion of aqueous humour (a liquid that maintains normal pressure in the eyeball) by the ciliary body into the eyeball. Thereby lowers the pressure in the eye by reducing aqueous humour entry into the eyeball.
You are recommended to maintain a minimum of 10 minutes time gap between using Levobunolol and other eye drops and administer eye ointments in the last.
You may need to stop using Levobunolol before surgery as it may alter the effects of certain medicines used during anaesthesia. Therefore, you are recommended to inform your doctor or dentist that you are using Levobunolol before any surgery or dental procedure.
Levobunolol is not recommended for asthma patients as it may cause bronchoconstriction (narrowing of airways). However, it is advised to inform your doctor if you have asthma before taking Levobunolol.
Pull your lower eyelid gently with your index finger to form a pocket. Instil the number of drops as advised by the doctor into the pocket of the lower eyelid. Close your eyes for 1-2 minutes.
