Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

RIVA-LABETALOL is used to treat high blood pressure (also known as hypertension) in adults.
RIVA-LABETALOL can be used alone or with other medicines to treat this condition.

What it does

RIVA-LABETALOL belongs to a group of drugs called “beta-blockers”.

  • It makes your heart beat more slowly and less forcefully.
  • It lowers your blood pressure by relaxing your blood vessels so that your blood flows more easily.
This medicine does not cure your disease but helps to control it. Therefore it is important to continue taking RIVA-LABETALOL regularly even if you feel fine.

  • Have severe heart damage and your heart is not able to pump enough blood to meet your body’s needs.
  • Have a slow or irregular heartbeat.
  • Have a problem with your heart’s electrical conduction (that causes you to have chest pain, difficulty breathing, nausea, fatigue and fainting).
