It can help prevent and reduce the risks of complications in individuals who previously had a heart attack.

This medicine may also be used to treat angina pectoris (chest pain) and prevent migraine headaches (severe throbbing or pulsating sensation usually affecting one side of the head and is often accompanied by nausea, vomiting, and sensitivity to light and sound).

Timolol may be used to treat other conditions as decided by your doctor.

What lifestyle changes can I make to improve my blood pressure?

Regular exercise and eating a healthy diet will help control your blood pressure and improve your overall health. Engage in physical activity like walking for at least 30 to 60 minutes on most days of the week. If you have not exercised for a long time, start with light exercises, such as slow walks. Speak to your doctor about what type of exercise would be suitable for you. Follow a healthy diet plan by eating more fruits, vegetables, whole grains, and low-fat dairy products and reduce your intake of foods high in saturated fat, cholesterol, and sodium. Cutting down on deep-fried foods and using less salt when cooking can kick-start your healthy diet.

If you smoke, you should try to quit. Smoking is harmful to your blood pressure, heart, and overall health. Speak to your doctor or pharmacist about ways to stop your smoking habit.
