Timolol maleate is a prescription medication which may be used to treat medical conditions such as hypertension, migraine headaches, or glaucoma. This medication is available in tablet form for oral use and in the form of eye drops for use in eye conditions such as glaucoma. Patients with certain medical conditions or those who take certain other medications may not be able to use timolol maleate. Some of the most common side effects of timolol maleate include low blood pressure, dizziness, and gastrointestinal disturbances. Any questions or concern about the use of this medication or the potential side effects should be discussed with a doctor or other medical professional.

Hypertension, more commonly referred to as high blood pressure, is sometimes treated with oral timolol maleate. This medication may be used alone or in combination with other medications designed to treat this condition. Patients with persistent migraines may be prescribed this medication, although it is not always successful in treating this type of headache. Timolol maleate is commonly used to treat an eye condition known as glaucoma and is available as an eye drop when used for this purpose. The patient should carefully follow the dosing instructions given by the doctor in order to reduce the risks of developing severe complications.


Some potential side effects of timolol maleate include dizziness, low blood pressure, hair loss, and an increased sensitivity to cold temperatures. Gastrointestinal disturbances associated with the use of this medication may include abdominal pain or cramping, nausea, diarrhea, or constipation. Some blood tests may come back abnormal when using this drug as well, so anyone drawing blood should be made aware that this medication is being used. While most side effects are relatively mild, some can be potentially life-threatening, making it extremely important for the patient to report all negative side effects to a doctor right away.

Some patients may not be able to use timolol maleate due to existing medical conditions or the use of certain medications. Women who are pregnant or breastfeeding are not candidates for this drug, and those who are considering getting pregnant should discuss the use of this drug with a doctor before taking it. Some medications, especially those used to treat blood pressure conditions or diabetes, may not interact well with this drug. The doctor should be made aware of all medications which are being taken, including over the counter and herbal treatments.
