Ever wondered if Inderal (propranolol) is still useful in 2025? Short answer: yes. It's a tried-and-true beta blocker used for several common problems. This page explains what it's for, how people take it, safety tips, and what to watch for.
Common uses include high blood pressure, certain heart rhythm problems, angina, migraine prevention, essential tremor, and performance anxiety. Doctors also use propranolol off-label for stage fright and some types of akathisia.
How it works: propranolol blocks beta receptors in the heart and nervous system. That lowers heart rate and reduces the force of each beat, which helps lower blood pressure and calms the physical signs of anxiety like shaking and a fast pulse.
Typical dosing varies by condition. For short-term anxiety control people often take 10–40 mg about an hour before an event. For blood pressure or long-term use usual doses run 40–320 mg per day, sometimes in divided doses. There are immediate and extended-release versions.
Expect effects on anxiety within an hour for immediate pills; blood pressure benefits may show after a few days. Full effects for migraine prevention can take several weeks.
Common side effects include tiredness, cold hands or feet, dizziness, sleep changes, and reduced exercise tolerance. Sexual side effects can happen. Serious problems include slow heart rate, low blood pressure, worsening asthma or breathing trouble, and signs of heart failure. If you faint or have severe breathing trouble get help right away.
Who should avoid it? People with active asthma, certain types of heart block, very slow resting heart rate, or uncontrolled heart failure should not take propranolol unless a doctor advises it. Use caution in diabetes because the drug can mask low blood sugar symptoms.
Interactions: propranolol can add effects with other blood pressure drugs, calcium channel blockers like verapamil or diltiazem, and some heart medications such as digoxin. Tell your doctor about all medicines, including antidepressants and herbal supplements.
For stage fright many people take a single 20–40 mg dose an hour before the event. For essential tremor and migraine prevention doctors usually set a daily schedule, often split into two doses. For blood pressure and heart rhythm problems the plan is tailored by your doctor and may require monitoring.
Take with food if it upsets your stomach. Check pulse and blood pressure. Never stop suddenly — taper with doctor. If pregnant or breastfeeding talk to provider. When buying online, use a licensed pharmacy that requires a prescription, has clear contact info, and good reviews. Avoid suspiciously cheap offers and sites without regulation. Keep regular checkups and blood pressure logs.
When to call doctor: chest pain, fainting, very slow pulse under 50, severe dizziness, breathing trouble, sudden weight gain or swelling. Bring a list of medicines to appointments. If something doesn’t feel right, ask — this drug works well for many but needs the right plan.
