COMMON BRAND NAME(S): Kerlone
WARNING: If you have chest pain (angina) or have heart disease (e.g., coronary artery disease, ischemic heart disease, high blood pressure), do not stop using this drug without first consulting your doctor. Your condition may become worse when the drug is suddenly stopped. If your doctor decides you should no longer use this drug, you must gradually decrease your dose according to your doctor's instructions.When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease the work on the heart. Seek immediate medical attention if you develop: worsening chest pain, tightness/pressure in the chest, chest pain spreading to the jaw/neck/arm, sweating, trouble breathing, or fast/irregular heartbeat.
USES: This medication is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Betaxolol 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 that affect the heart and blood vessels. This results in a lowering of the heart rate and blood pressure.
HOW TO USE: Take this medication by mouth, usually once daily with or without food or as directed by your doctor.Dosage is based on your medical condition and response to therapy. Patients with kidney disease should not take more than 20 milligrams daily.Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day.Keep taking this medication even if you feel well. Most people with high blood pressure do not feel sick.For the treatment of high blood pressure, it may take several months before the full benefit of this drug takes effect.Inform your doctor if your condition worsens (e.g., your routine blood pressure readings increase).
SIDE EFFECTS: Dizziness, lightheadedness, drowsiness, and headache may occur as your body adjusts to the medication. Trouble sleeping, decreased sexual ability, stomach upset, nausea, diarrhea, sore throat, cold hands and feet, dry eyes, tingling, numbness, and weakness may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.To reduce the 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 this medication has been prescribed because your doctor 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 right away if any of these unlikely but serious side effects occur: new or worsening symptoms of heart failure (such as shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain), slow/irregular heartbeat, back pain, mental/mood changes (e.g., depression, hallucinations), trouble breathing, joint pain, easy bruising/bleeding, increased thirst/urination, vision changes, slow wound healing, sweating, confusion, fainting, stomach/abdominal pain, blue fingers/toes/nails, finger/toe/leg cramps.A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: See also warning section.Before taking betaxolol, tell your doctor or pharmacist if you are allergic to it; or to other beta blockers (e.g., atenolol, metoprolol); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: certain types of heart rhythm problems (such as a slow heartbeat, second- or third-degree atrioventricular block), blood circulation problems (such as Raynaud's disease, peripheral vascular disease), breathing problems (such as asthma, chronic bronchitis, emphysema), glaucoma, heart failure, kidney disease, liver disease, mental/mood disorders (such as depression), a certain muscle disease (myasthenia gravis), skin conditions (such as psoriasis), overactive thyroid disease (hyperthyroidism), a certain type of tumor (untreated pheochromocytoma), serious allergic reactions (including those needing treatment with epinephrine).This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).If you have diabetes, this product may prevent the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). Other symptoms of low blood sugar level, such as dizziness and sweating, are not affected by this drug. This product may also make it harder to control your blood sugar levels. Check your blood sugar levels regularly as directed by your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet.Children may be at greater risk for low blood sugar (hypoglycemia), especially if they are vomiting or not eating regularly. To help prevent low blood sugar, feed children on a regular schedule. If your child cannot eat regularly, is vomiting, or has symptoms of low blood sugar (such as sweating, seizures), stop this medication and tell the doctor right away.Kidney function declines as you grow older. This medication is removed by the kidneys. Elderly people may be at a greater risk for slowed heartbeat while using this drug.This drug should be used only if clearly needed during pregnancy. Newborns whose mothers have taken this drug near the date of delivery may have problems such as low blood pressure, low heart rate and low birth weight, and may require special medical monitoring. Discuss the risks and benefits of taking this medication during pregnancy with your doctor.This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (such as prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug are: epinephrine, fenoldopam, fingolimod, general anesthesia, other heart drugs (e.g., digoxin), other drugs to treat high blood pressure (e.g., clonidine), St John's wort.Some products have ingredients that could raise your blood pressure. Tell your pharmacist what products you are using, and ask how to use them safely (especially cough-and-cold products, diet aids, or NSAIDs such as ibuprofen/naproxen).This medication may interfere with glaucoma screening tests, possibly causing false test results. Make sure your eye doctor knows you use this drug.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center.
