Quick GuideHeart Disease: Symptoms, Signs, and Causes
Which drugs or supplements interact with timolol?
- The concurrent use of timolol and clonidine (Catapres), may cause rebound hypertension upon abrupt discontinuation of clonidine. It is advisable, therefore, to stop the beta adrenergic blocking drug by several days before gradually withdrawing clonidine.
- Fenoldopam (Corlopam), which is used for the treatment of severe hypertension should not be taken together with timolol as the combination may increase the risk of hypotension due to additive effects of the two drugs in lowering blood pressure.
- Close observation should be carried out when timolol is administered to patients receiving catecholamine-depleting drugs such as reserpine (Harmonyl) because of possible additive effects and the production of hypotension and/or a markedly slow heartbeat, which may produce dizziness, syncope, or postural hypotension (dizziness upon standing).
- Concurrent use of NSAIDs with timolol may cause the antihypertensive action of beta-blockers to be decreased. This occurs because prostaglandins are important in controlling blood pressure.
Is timolol safe to take if I'm pregnant or breastfeeding?
- There are no adequate studies in pregnant women. Timolol should be used during pregnancy only if the potential benefit justifies the potential risk.
- Timolol has been detected in human milk and has a potential for adverse events in infants.
What else should I know about timolol?
What preparations of timolol are available?
Tablets: 5, 10, and 20 mg.
How should I keep timolol stored?
Timolol should be stored at room temperature, 15 C - 30 C (59 F - 86 F) and kept in a tightly sealed container protected from light

Angina SymptomsAngina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Arrhythmia (Irregular Heartbeat)An arrhythmia is an abnormal heart rhythm. With an arrhythmia, the heartbeats may be irregular or too slow (bradycardia), to rapid (tachycardia), or too early. When a single heartbeat occurs earlier than normal, it is called a prmature contraction.

Heart Disease (Coronary Artery Disease)
Heart disease (coronary artery disease) occurs when plaque builds up in the coronary arteries, the vessels that supply blood to the heart. Heart disease can lead to heart attack. Risk factors for heart disease include:
- High blood pressure
- High cholesterol
- Family history
Angina, shortness of breath, and sweating are just a few symptoms that may indicate a heart attack. Treatment of heart disease involves control of heart disease risk factors through lifestyle changes, medications, and/or stenting or bypass surgery. Heart disease can be prevented by controlling heart disease risk factors.

Heart: How the Heart WorksThe heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
High Blood Pressure HypertensionHigh blood pressure is defined as a pressure of 140/90 mmHg or higher in the arteries. Genetic factors, high salt intake, and increased arterial stiffness cause high blood pressure. Dizziness, headache, nausea, and shortness of breath are just a few symptoms of high blood pressure. Untreated high blood pressure increases the risk of heart disease, kidney disease, atherosclerosis, eye damage, stroke, and increased risk of aneurysms. High blood pressure can be managed with weight loss, lifestyle changes, and medication.

- Certain foods
- Changes in barometric pressure
- Other phenomenon
They are diagnosed by a doctor if the headache pattern fits established migraine headache criteria. Over-the-counter (OTC) and prescription medications are sometime used to treat acute migraines. To prevent or reduce the frequency and severity of them doctors recommend supplements and prescription medications, for example:
- Blood pressure drugs
- Anti-seizure drugs
Lifestyle modification helps in migraine management. Many people who suffer from migraines get relief from their condition by keeping a headache diary, identifying and avoiding triggers, and taking appropriate medication.

Most patients do not need any treatment, however, patients with severe prolapse may need treatment.
