Function
What is the effect of timolol?
Timolol is used with or without other drugs to treat hypertension. Lowering high blood pressure helps prevent stroke, heart attack and kidney problems. Timolol is also used after a heart attack to help prevent another heart attack.

Timolol belongs to the beta blockers group, which works by blocking the action of certain natural substances in the body such as epinephrine on the heart and blood vessels. This effect reduces the heart rate, blood pressure, and heart pressure.

Timolol is also used to prevent migraines and prevent chest pain (chronic stable angina).

How should you use timolol?
Take with or without food, usually once or twice a day or as directed by your doctor.

Dosage is based on health status and response to treatment. To treat hypertension, do not take more than 60 mg a day. To prevent migraines, do not take more than 30 mg a day.

Take medication regularly to get the best results. To help you remember, take medication at the same time every day.

For treatment of hypertension, it may take several weeks for the drug to develop its full potential. Continue to take medication even when you feel better. Most people with hypertension do not feel sick.

To prevent chest pain or migraines, take regular medication as directed.

This medicine should not be used to treat chest pain or migraines when these conditions occur. Use other drugs to relieve angina and sudden migraine as directed by your doctor (for example: head). Consult your doctor or pharmacist for details.

Tell your doctor if your condition is not improving or deteriorating (for example, if your blood pressure level is high or increasing if your angina or migraine occurs more frequently). .
