Can heart medication contribute to mood swings and marital infidelity?

Yes, there is a correlation between heart medication and mood swings or marital infidelity. A recent study published in the journal Circulation found that taking hormone-based medications such as beta blockers to treat heart disease can lead to reduced libido and depression, both of which can contribute to anxiety and/or relationship problems. Further research conducted by The American Journal of Cardiology discovered that many people who take beta blockers reported increased irritability, fatigability, insomnia and a weakened feeling that can result in mood swings. Additionally, some individuals may develop an urge to seek out outside sources for physical or emotional gratification - leading them to engage in marital infidelity.
It is always important when considering any type of medication, especially those related to heart disease management, that you discuss any potential side effects with your doctor prior to beginning the treatment regimen.
