The Side Effects of Metoprolol Succinate

Metoprolol Succinate is a prescription medication used to treat several heart conditions, including angina, high blood pressure and heart failure. It is classified as a beta blocker and works by reducing the amount of blood the heart has to pump and the amount of work it has to do, effectively decreasing heart pain and lowering blood pressure. Metoprolol Succinate can also be used to stabilize a person's heart rate in the case of a fast or irregular heart rate. People with angina or certain kinds of heart disease should never suddenly stop taking Metoprolol Succinate without a doctor's approval because it can cause the condition to worsen. Taking the drug has several known side effects.

Cardiac Side Effects

• In rare cases, Metoprolol Succinate may cause serious side effects that may indicate a problem with the heart. Patients who experience any of the following symptoms should contact their doctor immediately: worsening chest pain, a pounding feeling in the chest or a slowing or irregular heartbeat.

Gastrointestinal Side Effects

• Some people may experience constipation, diarrhea, heartburn, nausea, vomiting, stomach pain and gas. However, none of these side effects is cause for concern.
