What is pindolol?
USES: This medication is used alone or with other medications to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks and kidney problems. Pindolol belongs to a class of medications called beta-blockers. It works by blocking the effects of certain natural substances (such as epinephrine) on the heart and blood vessels. This results in a lowering of the heart rate, blood pressure, and strain on the heart.

It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

Interactions with pindolol
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 (including 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 include: alpha-blockers (e.g., prazosin), arbutamine, other beta-blockers (e.g., atenolol), clonidine, epinephrine, fenoldopam, fingolimod, thioridazine, other drugs for high blood pressure (e.g., methyldopa), drugs affecting liver enzymes that remove this medication from your body (e.g., amiodarone, chlorpromazine, St. John's wort). Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine). Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain ingredients that cause drowsiness. Ask your pharmacist about using those products safely. Some products have ingredients that could raise your heart rate or 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).
PRECAUTIONS: Before taking pindolol, tell your doctor or pharmacist if you are allergic to it; or to other beta-blockers (e.g., acebutolol); 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: severe allergic reactions (e.g., anaphylaxis), breathing problems (e.g., asthma, chronic obstructive lung disease-COPD, emphysema, chronic bronchitis), blood circulation problems (e.g., Raynaud's disease, peripheral vascular disease), low blood flow to the heart/brain (e.g., due to coronary artery disease, stroke, transient ischemic attack), diabetes, heart problems (e.g., heart failure, heart attack, slow heartbeat), kidney disease, liver disease, mental/mood disorders (e.g., depression), a certain muscle problem (myasthenia gravis), overactive thyroid (hyperthyroidism), a certain type of tumor (pheochromocytoma). This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely.

Tell your doctor right away if you develop symptoms of high blood sugar such as increased thirst or frequent urination. If you have diabetes, this medication may mask the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). Other symptoms of a low blood sugar level such as dizziness and sweating are unaffected by this drug. Kidney function declines as you grow older. This medication is removed by the kidneys and liver. Therefore, elderly people may be at greater risk for side effects such as dizziness while using this drug. This medication should be used only when clearly needed during pregnancy.
