Which condition is a contraindication for using Prozac and Zoloft?

The condition that serves as a contraindication for using Prozac (fluoxetine) and Zoloft (sertraline) is heart block. Both medications are selective serotonin reuptake inhibitors (SSRIs) and are primarily used to treat depression and anxiety. Individuals with heart block experience an electrical conduction issue in the heart, which can be exacerbated by certain medications, including SSRIs. These drugs can potentially lead to cardiac side effects such as changes in heart rate and rhythm, which can be dangerous for someone already experiencing heart conduction issues.

Heart block can lead to serious complications, including syncope (fainting) or even more severe cardiac events, if the electrical signals in the heart are further disrupted. Therefore, in patients with this condition, alternative treatment options that do not pose the same risk would be recommended to ensure their heart health is not compromised.
