Metoprolol Side Effects

Though the medication was created to help sustain the most important muscle in your body (the heart), potential Metoprolol side effects shouldn’t just be ignored. Chemically, Metoprolol is a member of the “beta blocker” class of drugs. That is, it affects signals that your nervous system sends to the rest of your body, indirectly working to decrease the everyday “workload” that is put on your heart. Its most common uses are to treat hypertension and to lower the risk of heart attack. As important as this function is, there is a chance of some pretty serious side effects associated with the use of Metoprolol. Read on to find out what to watch out for if you’re considering this drug.

  1. Depression. Though the reason behind psychological side effects of beta blockers such as Metoprolol is debated, there is a risk of developing symptoms of depression as a result of its use. In general, the explanation likely lies within the fact that Metoprolol affects the release of certain neurotransmitters, such as melatonin, that control your psychological state.
  2. Gastrointestinal effects. Another commonly reported set of problems associated with Metoprolol are side effects related to the stomach. In studies, nausea, vomiting, and excessive gas have been documented. Again, the specific reason as to why beta blocker drugs tend to cause this isn’t fully known. It is important to note, however, that these symptoms are rarely considered serious by medical professionals.
  3. Limited reaction and confusion. By now, you should notice a sort of pattern developing. Any time you mess with the neurotransmission process in the brain, some strange things can happen. Those who are just starting Metopropol, therefore, are advised not to drive or operate machinery until they know their personal side effects regarding cognitive ability. In some cases, dizziness, reduced thinking ability, and higher reaction times have been associated with Metoprolol. If you experience any of these side effects, it is recommended that you talk to your doctor to decide whether quitting the medication is your best option. Making the decision to quit taking it on your own is very strongly discouraged.
  4. Breastfeeding Implications. Like many other medications, Metoprolol is distributed throughout the body when ingested – which includes breast milk in the case of nursing mothers. Though there aren’t any birth defects associated with taking Metoprolol while pregnant, an infant directly ingesting it through breast milk is potentially harmful. Makers of the medication recommend that you respond to this possible side effect of Metopropol by having a conversation with your own doctor. He or she can help to determine the safety of breastfeeding while taking it.
