Some eye drops can cause drowsiness, while others do not. It depends on the specific medication in the eye drops.
Eye Drops That May Cause Drowsiness
Several sources indicate that certain eye drops can lead to drowsiness or tiredness as a side effect. These include:
-
Brimonidine: Multiple references (Mayo Clinic, MedlinePlus, and other sources) explicitly state that brimonidine eye drops may cause drowsiness, dizziness, lightheadedness, tiredness, or reduced alertness. The American Academy of Ophthalmology advises against driving or operating machinery if your glaucoma eye drops make you feel tired or drowsy. It's crucial to be aware of this potential side effect before using brimonidine and to follow your doctor's instructions regarding driving and operating machinery.
-
Other Glaucoma Medications: While not all glaucoma medications have this effect, the potential for drowsiness exists with some. The possibility of drowsiness emphasizes the importance of caution and careful consideration of one's activities after application. Always follow your doctor's instructions. They may recommend adjustments to minimize these effects.
-
Tetrahydrozoline (in some over-the-counter red-eye drops): When ingested in high amounts, tetrahydrozoline can cause sleepiness. While not typically a side effect from normal topical use, this highlights the importance of not ingesting eye drops.
Eye Drops That Typically Do Not Cause Drowsiness
Many eye drops, particularly those used for lubrication or treating minor irritations, do not typically cause drowsiness. However, always read the label and consult your doctor or pharmacist if you have any concerns about potential side effects.
Important Considerations
- Always read the label: The package insert for your specific eye drops will list potential side effects.
- Consult your doctor: If you experience drowsiness or any other concerning side effects after using eye drops, consult your doctor immediately.
- Do not drive or operate machinery: If your eye drops make you feel drowsy, avoid activities that require alertness.
