Heart-failure symptoms can take several weeks before improvement is seen. If you need to stop taking Coreg, consult your physician and decrease the amount taken over one to two weeks under her direction.
If you experience symptoms of low blood pressure when standing, such as dizziness or lightheadedness, it may be helpful to get up slowly and avoid standing suddenly.
Warnings

Sudden discontinuation of Coreg could cause heart attack or chest pain. According to the U.S. Food and Drug Administration, Coreg is not recommended for people with severe heart failure, asthma, irregular heartbeat or liver problems. Taking Coreg with rifampin (Rifadin) can decrease the level of Coreg in your body by 70 percent, rendering the drug ineffective.
