Inderal is classified as a beta-blocker, which influences both the heart and the circulatory system (blood flow through arteries and veins).
Inderal is prescribed for the treatment of tremors, angina (chest pain), hypertension (high blood pressure), heart rhythm issues, and various other heart or circulatory disorders. Additionally, it is utilized to treat or prevent heart attacks and to lessen the intensity and occurrence of migraine headaches.
Inderal functions by inhibiting beta-adrenergic substances like adrenaline (epinephrine), an important element of the "sympathetic" part of the autonomic (involuntary) nervous system that manages heart activity. This medication is indicated for tremors, chest pain, hypertension, heart rhythm issues, ischemic heart disease, hypertrophic cardiomyopathy, myocardiodystrophy, and other related conditions.
Administer the medication orally without regard to meals. Use Inderal with a full glass of water at the same time each day. Avoid chewing, crushing, breaking, or opening an Inderal capsule; swallow the tablet whole. Do not abruptly discontinue the medication, as this may lead to heart problems.
Avoid using Inderal if you have asthma or specific heart issues, particularly second or third-degree heart block, liver or kidney failure. Steer clear of alcohol. Even if you feel better, do not cease taking the medication, as hypertension can be asymptomatic.
Conditions such as sinus bradycardia, incomplete or complete atrioventricular block (issues with the heart's excitation-conduction system), severe right and left ventricular failure, bronchial asthma with a tendency towards bronchospasm, pregnancy, and disorders affecting peripheral arterial blood flow are also contraindications. Inderal is generally not recommended for patients with spastic colitis (inflammation and contraction of the colon).
Potential side effects include nausea, vomiting, diarrhea, bradycardia (slow heartbeat), dizziness, allergic reactions such as itchy skin, and bronchospasm (constriction of the bronchus). There is a possibility of experiencing depression.
Alcohol and aluminum can hinder the absorption of propranolol. Inderal may raise blood levels of theophylline and lidocaine. Conversely, phenytoin, phenobarbital, and rifampin can lower Inderal's blood levels. Cimetidine and chlorpromazine can increase the blood levels of Inderal.
If you forget a dose of short-acting Inderal, take it as soon as you remember, unless there are only about four hours left until your next dose. In that case, skip the missed dose and resume your regular schedule. If you miss an extended-release Inderal dose, take it as soon as possible, unless less than eight hours remain until the next dose. Never double up on doses to make up for a missed one.
