What Inderal Does to the Heart and Body
Inderal contains propranolol, which occupies the beta receptors that normally answer to adrenaline and noradrenaline. The heartbeat slows and weakens a little, blood pressure drops and the heart muscle needs less oxygen. Since Inderal acts on beta-1 and beta-2 receptors alike, it also touches the airways and can hide some of adrenaline's effects.
Conditions Treated With Inderal
Inderal is a prescription beta-blocker. The Canadian monograph and standard references list high blood pressure, angina (chest pain from limited blood flow to the heart), some abnormal heart rhythms, prevention of another heart attack, migraine prevention, essential tremor and a few further indications. A doctor picks Inderal and its dose after looking at your diagnosis and general health.
Inderal Dose Ranges
Treat the numbers below as general information from the monograph. Only a doctor sets the Inderal dose, normally starting small and adjusting step by step.
- Hypertension: a low starting dose given twice daily, raised as needed; typical daily totals sit around 120 to 240 mg.
- Angina: the daily total is spread over several doses and may run from roughly 80 to 320 mg.
- Migraine prevention: usually about 80 to 160 mg daily, divided.
- Essential tremor: treatment starts low, and the monograph gives a usual range near 120 to 240 mg per day.
Taking Inderal Properly
- Swallow Inderal with water at the same hours each day, and be consistent about taking it either with food or without.
- Measure your pulse and blood pressure as your doctor suggests.
Never Stop Inderal Suddenly
Abruptly dropping Inderal can worsen angina, set off an irregular heartbeat and, rarely, bring on a heart attack. The doctor therefore lowers the dose gradually over one to two weeks.
People Who Must Not Use Inderal
- Bronchial asthma, a history of wheezing or other obstructive airway disease.
- A very slow heartbeat, particular types of heart block, sick sinus syndrome or cardiogenic shock.
- Heart failure that is severe or not controlled.
- Serious peripheral artery disease or very low blood pressure.
- Allergy to propranolol or to any other ingredient of Inderal.
Report diabetes, thyroid disease, kidney or liver disease, earlier heart failure or severe allergies to your doctor before Inderal is started.
Inderal Can Mask Hypoglycemia
Inderal may hide the alarm signals of low blood sugar, notably a racing heart and shaking. People with diabetes who use insulin or other diabetes medicines should check their glucose as advised. Sweating can still serve as a warning.
Inderal Side Effects
Frequent Inderal side effects
- fatigue, dizziness or a lightheaded feeling;
- a slow heart rate;
- cold hands and feet;
- disturbed sleep and vivid dreams;
- an upset stomach, with nausea or diarrhea.
The Inderal product monograph gives the frequency of every effect.
Inderal symptoms that need urgent medical help
- wheezing, breathlessness or a tight chest;
- fainting, a very slow or irregular pulse, or chest pain;
- swollen ankles with quick weight gain, a sign of heart failure;
- swelling of the face, lips or tongue, or a rash that spreads widely.
Any of these requires urgent medical attention.
Inderal Drug Interactions
- Verapamil, diltiazem and some antiarrhythmic drugs: together with Inderal they may slow the heart too much.
- Other blood pressure drugs: the effects add up and pressure may fall too far.
- Insulin and diabetes drugs: blood sugar response may shift.
- Clonidine: if clonidine is stopped during Inderal treatment, blood pressure can jump sharply, and the doctor manages this.
- Epinephrine (adrenaline): reactions may be stronger, so tell emergency staff you take Inderal.
- NSAIDs, cimetidine, rifampin and alcohol: any of these can alter propranolol's effect.
Inderal While Pregnant or Breastfeeding
A doctor should prescribe Inderal in pregnancy only if the benefit outweighs the risk, since beta-blockers may slow the baby's heart rate and growth. Small amounts of propranolol appear in breast milk, so discuss feeding with your doctor.
Inderal, Alcohol and Driving
Dizziness and tiredness are possible with Inderal, especially early on. Alcohol lowers blood pressure further. Wait until you know how Inderal affects you before getting behind the wheel.
Inderal Storage and Missed Doses
- Keep Inderal tablets at room temperature, shielded from light and moisture, and away from children.
- If a dose slips by, take Inderal when you remember, unless the next one is close, and never double up.

Inderal: Frequently Asked Questions
Who prescribes Inderal and sets its dose?
A doctor does. Inderal is a prescription medicine, and the doctor supervises the whole treatment.
What Inderal tablet strengths are listed here?
Inderal is listed as propranolol tablets of 10, 20, 40 and 80 mg, in packs of 30 to 360 tablets. Choose the strength your doctor prescribed.
Why does Inderal affect people with asthma differently?
Inderal blocks beta-2 receptors in the airways, which can make them narrow. For that reason it is not suitable for people with asthma, and a doctor can suggest alternatives.
