Effects of Propranolol Sustained-Release

By lowering blood pressure, propranolol sustained-release can decrease the risks that accompany long-term high blood pressure (see Effects of High Blood Pressure). By reducing the heart's workload, it can also decrease symptoms of angina, including chest pain. Propranolol sustained-release can decrease the frequency of migraines as well, although the way in which it does this is not clear.

When and How Do I Take This Drug?

Some general considerations for when and how to take propranolol sustained-release include the following:
  • Propranolol sustained-release comes in capsule form and is taken once a day.
  • This medication may be taken with or without food.
  • Do not break, chew, or crush the capsules.
  • Your dosage should be taken at the same time each day to maintain an even level in your blood.
  • For propranolol sustained-release to work properly, you have to take it as prescribed. The drug will not work if you stop taking it.
You should not stop taking this medication without first discussing it with your healthcare provider. Abruptly stopping treatment increases the risk of serious side effects (see Precautions and Warnings With Propranolol Sustained-Release).

Dosing Information

The dose of propranolol sustained-release your healthcare provider recommends will vary, depending on a number of factors, including:
  • Your age
  • The medical condition being treated
  • Other medical conditions you have
  • Other medications you are currently taking
  • How you respond to propranolol sustained-release.
As always, do not adjust your dose unless your healthcare provider specifically instructs you to do so.
