Indications
- Lopressor is prescribed to treat high blood pressure (hypertension).
- It is also used to prevent chest pain (angina) and to improve survival after a heart attack.
- Lopressor belongs to a class of drugs known as beta blockers, which work by blocking the action of certain natural chemicals in the body, such as adrenaline, on the heart and blood vessels.
- Follow your doctor’s instructions carefully regarding the dosage and duration of treatment with Lopressor.
Dosage and administration
- Take Lopressor exactly as prescribed by your doctor.
- It is usually taken by mouth with or immediately after meals.
- Swallow the tablet whole with a glass of water. Do not crush or chew the tablet.
- The dosage is based on your medical condition and response to treatment.
- To reduce the risk of side effects, your doctor may start you at a low dose and gradually increase it.
- Take Lopressor regularly to get the most benefit from it. It is important to take it at the same time(s) each day.
- Do not suddenly stop taking Lopressor without consulting your doctor, as this may worsen your condition. Your doctor may gradually reduce your dose over time.
- If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Do not double the dose to catch up.
- Continue taking Lopressor even if you feel well. Most people with high blood pressure do not feel sick.

Precautions
- Before taking Lopressor, inform your doctor if you have any allergies to this medication, other beta blockers, or any other substances.
- Share your medical history with your doctor, especially if you have certain heart conditions (such as heart block, sick sinus syndrome), breathing problems (such as asthma, chronic bronchitis, emphysema), liver disease, kidney disease, or a certain muscle disease (myasthenia gravis).
- Inform your doctor about all the medications you are currently taking, including prescription drugs, over-the-counter medications, vitamins, and herbal supplements, to avoid any potential interactions.
- Limit alcoholic beverages while taking Lopressor, as alcohol may increase the risk of side effects.
- Before having surgery, including dental surgery, inform your doctor or dentist about all the products you use, including Lopressor.
- If you are diabetic, Lopressor may mask the symptoms of low blood sugar, such as fast heartbeat. Monitor your blood sugar levels regularly and inform your doctor of any changes.
- Avoid activities that require alertness, such as driving or operating machinery, until you know how Lopressor affects you.
- Contact your doctor if you experience symptoms such as shortness of breath, swelling of the hands or feet, or sudden weight gain, as these may indicate a worsening of your condition.
- Do not suddenly stop taking Lopressor without consulting your doctor, as this may lead to rebound high blood pressure or other complications. Your doctor may need to gradually reduce your dose.
