Timolol is a beta blocker that is used to lower blood pressure and to improve the chances of survival following a heart attack. It may also be prescribed to treat migraine headaches. This medication works by slowing the heart rate and relaxing blood vessels in order to help blood flow more easily through the veins and reduce the stress on the heart.
Patients should never abruptly stop taking this medication. If a patient wants to stop taking the medication, he or she should gradually withdraw from it while under the care of a doctor. Stopping this medication too quickly can cause chest pain and increases the risk of a sudden heart attack.
