What common side effect is associated with SNRIs?

The correct answer is sexual dysfunction, which is a well-documented side effect associated with serotonin-norepinephrine reuptake inhibitors (SNRIs). These medications work by increasing the levels of serotonin and norepinephrine in the brain, which can lead to improvements in mood and anxiety. However, the alteration in neurotransmitter levels can also disrupt normal sexual functioning. Patients may experience issues such as decreased libido, erectile dysfunction, or difficulty achieving orgasm.

Understanding this side effect is crucial for healthcare providers and patients alike, as it can impact adherence to treatment. While other side effects such as constipation, visual disturbances, and tremors can occur with different classes of medications, they are not specifically noted as common side effects tied to SNRIs. Addressing potential sexual dysfunction before initiating treatment can help mitigate its impact on a patient's quality of life and encourage open communication about side effects during treatment.
