Blood Pressure Home > Inderal


By lowering blood pressure, Inderal can decrease the risks that accompany long-term high blood pressure (see Effects of High Blood Pressure). By decreasing the heart's workload, the medication can decrease symptoms of angina, including chest pain. Although the exact mechanism is not known, Inderal can increase the survival rate in people who have just suffered a heart attack.

When and How Do I Take Inderal?

Some general considerations for when and how to take the medication include:
  • It comes in tablet form and is taken two to four times a day based on your healthcare provider's recommendation.
  • An injectable form is also available for use in treating irregular heart rhythms (usually in emergency situations). It is generally recommended to take this medication on an empty stomach.
  • It should be taken at the same times each day to maintain an even level of medicine in your blood.
  • For Inderal to work properly, you have to take it as prescribed. It will not work if you stop taking it.
  • You should not stop taking it without first discussing it with your healthcare provider. Stopping Inderal abruptly increases the risk of serious side effects (see Inderal Precautions and Warnings).


The dosage that your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age
  • The medical condition you are being treated for
  • Other medical conditions you may have
  • Other medications you may be currently taking
  • How you respond to Inderal.
As with any medication, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
