Propranolol 10 mg 20 mg 40 mg 60 mg 80 mg Extended Release 60 mg 80 mg 120 mg 160 mg

What is Propranolol?

Propranolol is a prescription beta blocker medicine used to treat high blood pressure, control certain heart rhythm problems, prevent migraines, reduce tremors, and protect the heart after a heart attack. It can also be used for specific anxiety situations, such as performance anxiety, when a racing heart and tremor need to be controlled.

It is available in immediate release tablets of 10 mg, 20 mg, 40 mg, 60 mg, and 80 mg, as well as extended release capsules of 60 mg, 80 mg, 120 mg, and 160 mg. The different forms allow dosing flexibility depending on the condition and desired duration of effect. Because propranolol is widely available as a generic, many people compare prices for cheap refills or buy it online from licensed U.S. pharmacies, making sure the source is legitimate with clear labeling and an expiration date.

How It Works

Propranolol works by blocking beta adrenergic receptors in the heart, blood vessels, and other tissues. This reduces the effects of adrenaline (epinephrine) and related stress hormones, leading to slower heart rate, lower blood pressure, and reduced strain on the heart. In migraine prevention, propranolol is thought to stabilize blood vessel tone and reduce nerve excitability that can trigger headaches.

Because it is a non selective beta blocker, propranolol affects both beta 1 receptors (heart) and beta 2 receptors (lungs and blood vessels), which can be beneficial for some conditions but requires caution in people with asthma or other lung diseases.

What you may notice

Lower heart rate, steadier blood pressure, fewer episodes of chest pain or migraine, and reduced tremor. Some people feel less shaky in anxiety provoking situations. Fatigue or cooler hands and feet can occur as circulation changes.

Dosage Information

Dosing depends on the condition, formulation, and your response. Always follow your prescription label.

• High blood pressure (immediate release): Usually starts at 40 mg twice daily, may increase to 80 mg twice daily or more if needed.
• High blood pressure (extended release): 80 mg once daily, increased gradually as needed.
• Angina: 40 mg two or three times daily for immediate release, or 80 mg once daily for extended release.
• Migraine prevention: Start at 40 mg two or three times daily; extended release 80 mg once daily may be used.
• Tremor: 40 mg twice daily, adjusted based on effect.
• Performance anxiety: A single dose of 10 mg to 40 mg taken about 30 to 60 minutes before the event.

How to take it

Swallow tablets or capsules whole with water. Take immediate release forms at evenly spaced times. For extended release, take at the same time each day. Do not crush or chew extended release capsules. If you miss a dose, take it when remembered unless it is almost time for the next dose—then skip it. Do not double up.

Cost and access tips

Generic propranolol is inexpensive and widely available. Buying from licensed online pharmacies can lower costs. Cheap pricing is fine when the label, strength, and expiration date are clear and a pharmacist is available for questions.

Side Effects

Common side effects include tiredness, dizziness, slower heart rate, cold hands or feet, and mild stomach upset. These often improve as your body adjusts.

Less common but important

• Worsening asthma or breathing problems: Due to beta 2 blockade in the lungs. Avoid in people with asthma unless approved by a specialist.
• Low blood sugar symptoms: Can mask warning signs like rapid heartbeat in people with diabetes.
• Depression or mood changes: Report new or worsening mood symptoms to your clinician.
• Heart block or severe bradycardia: Can occur in susceptible individuals; requires monitoring.

Contact your clinician if you experience fainting, very slow pulse, trouble breathing, or swelling in the legs.

Warnings & Interactions

Propranolol should be used with caution in people with asthma, chronic lung disease, diabetes, low blood pressure, certain heart rhythm disorders, or depression. Do not stop suddenly—this can cause rebound high blood pressure, chest pain, or even heart attack in people with heart disease.

Drug interactions

• Other blood pressure medicines: Additive effects can cause low blood pressure or slow heart rate.
• Diabetes medicines: Can mask symptoms of low blood sugar; monitor closely.
• Asthma medicines: Beta blockers can counteract the effect of beta agonist inhalers.
• Blood thinners: May interact with warfarin; monitor INR as directed.

Practical safety tips

Check heart rate and blood pressure regularly. Carry a list of your medicines. If buying propranolol online, choose licensed U.S. pharmacies, verify the strength and expiration date, and ensure labeling is clear. Cheap pricing is acceptable when those checks are met.
