There are four oral tablet strengths of Inderal: 10 mg, 20 mg, 40 mg, and 60 mg. It can also be obtained as an injectable solution administered by a medical professional.

40 mg twice daily is typically the first dose for high blood pressure. Your doctor might increase your dosage to 80 mg twice daily if you tolerate the drug well.

The recommended starting dose for angina is 10–20 mg administered three–four times daily, preferably before painful activities.

The typical starting dose for migraines is 40 mg twice daily. Your doctor may increase your dose up to 320 mg per day if you still don't feel better after the first week.

Mechanism of Action

The heart's nerves contain beta-adrenergic receptors, which are blocked by inderal.This lessens heart rate, blood pressure, and heart effort by preventing norepinephrine and epinephrine from binding to these receptors.Inderal is thought to treat migraines by preventing serotonin, a neurotransmitter involved in pain signaling, from being active.


If you take any other medications, herbs, or vitamins, Inderal might interact with them. When a substance modifies how a drug functions, there is an interaction. This could be harmful or stop the medication from working properly.

Your doctor needs to carefully monitor all of your medications to help you avoid interactions. Tell your doctor about all prescription drugs, over-the-counter remedies, and dietary supplements you use.

If you take any of these medications, tell your doctor:

Tagamet (cimetidine)

Prozac Fluoxetine

Nizoral (ketoconazole)

Dilantin (phenytoin)

Combining Inderal with these medications can raise the amount of the drug in your body and increase the side effects.

Other beta blockers, calcium channel blockers, or heart medications may also interact with inderal.
