All of these options are potential side effects associated with beta blockers, but only sexual dysfunction is specifically linked to this type of medication. While beta blockers can cause a decrease in heart rate (bradycardia), they are actually often prescribed to treat conditions like high blood pressure, which involve a fast heart rate. Bronchospasm (constriction of the airways) and fatigue are also potential side effects, but they are not directly linked to beta blockers and may be caused by other factors. On the other hand, sexual dysfunction is a known side effect of beta blockers and can include decreased libido, erectile dysfunction, and difficulty achieving orgasm. It is important to discuss any potential side effects with your doctor when taking beta blockers.
