Effectiveness

How Lopressor Affects PatientsMetoprolol is a drug used to treat heart rate and cardiac output issues. It works by slowing the electrical signals that control the heart and reducing the amount of blood the heart pumps out. The MAPHY trial showed that metoprolol reduced sudden cardiac death and heart attack when compared to diuretics. Another 1990 study found that taking metoprolol after a heart attack reduced the risk of death and repeat heart attack by 17%.
How Lopressor works in the bodyMetoprolol works by blocking certain receptors in the heart. This reduces the heart's rate and strength of contractions, without affecting other parts of the body.

Lopressor Toxicity & Overdose RiskThe lethal dose of metoprolol in rats has been found to be between 3090 and 4670 mg/kg. Overdosing on metoprolol may cause a slow heartbeat, low blood pressure, difficulty breathing, and heart failure. To treat an overdose, doctors recommend emptying the stomach and then providing treatment based on the symptoms. Metoprolol has not been linked to cancer, mutations, or fertility problems, although long-term use of high doses may cause minor lung tumors.

Lopressor for High Blood Pressure
I started out by taking 1/2 tablet of this medication twice a day, in addition to 100mg of Losartran for my high blood pressure. When that didn't work, they upped my Lopressor dosage to one whole tablet twice a day. I still haven't seen any improvement in my BP and now my feet are swollen, mouth is dry, appetite is gone, and sleep patterns are all off. I'm not feeling well at all and wonder if it's even worth continuing this treatment. I have to call the cardiologist on Friday but, in the meantime, am really struggling with these side effects.
