Medication effects: Sometimes medicated eye drops are absorbed into the blood stream and can exert effects on other organ systems. In certain patients beta blocker drugs may cause heart vessel or lung 'tubes' spasm or slowing of the heart rate, which in turn may cause chest discomfort.

Side effect: If you notice chest pain or tightness or breathing difficulty, you should discontinue timolol and call your eye doc about your symptoms. He/she will more than likely switch you to a different class of medication.
