Uses

Timolol is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used after a heart attack to help prevent another heart attack from occurring.

This medication belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body such as epinephrine on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.

This medication is also used to prevent migraine headaches.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used to prevent chest pain (chronic stable angina).

How to use timolol

See also Warning section.

Take this medication by mouth with or without food, usually once or twice a day or as directed by your doctor.

Dosage is based on your medical condition and response to treatment. For the treatment of high blood pressure, do not take more than 60 milligrams a day. For the prevention of migraines, do not take more than 30 milligrams a day.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.

For the treatment of high blood pressure, it may take several weeks before you get the full benefit of this drug. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

To prevent chest pain or migraine headaches, it is very important to take this medication regularly as prescribed. This drug should not be used to treat chest pain or migraines when they occur. Use other medications to relieve sudden attacks as directed by your doctor (for example, nitroglycerin tablets placed under the tongue for chest pain, "triptan" drugs such as sumatriptan for migraines). Consult your doctor or pharmacist for details.

Tell your doctor if your condition does not improve or if it worsens (for example, if your routine blood pressure readings remain high or increase, if your chest pain or migraines occur more often).

Side Effects

See also Warning and Precautions sections.

Tiredness, slow heartbeat, and dizziness may occur. Decreased sexual ability has been reported infrequently. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

To lower your risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

This drug may reduce blood flow to your hands and feet, causing them to feel cold. Smoking may worsen this effect. Dress warmly and avoid tobacco use.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur: very slow heartbeat, severe dizziness, fainting, blue fingers/toes, trouble breathing, new or worsening symptoms of heart failure (such as swelling ankles/feet, severe tiredness, shortness of breath, unexplained/sudden weight gain), mental/mood changes (such as confusion, mood swings, depression).

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
