Which statement about SNRI withdrawal is noted in the material?

• A. Benzodiazepines are the only medications with withdrawal concerns.
• B. SSRIs have no withdrawal issues.
• C. Antipsychotics have withdrawal concerns.
• D. SNRIs are associated with withdrawal symptoms upon discontinuation.

Answer: (D)

The important idea here is that stopping SNRI antidepressants can lead to withdrawal symptoms. This happens because SNRIs raise both serotonin and norepinephrine levels during use, and when you suddenly reduce or stop the dose, the brain moments later has to readjust to lower monoamine activity. Because some SNRIs have relatively short half-lives, levels fall quickly after a missed dose, making withdrawal symptoms more likely and sometimes more noticeable. Common withdrawal effects include flu-like feelings (fatigue, achiness, malaise), sleep disturbances, dizziness, headaches, nausea, and unusual sensory experiences such as electric shock sensations. Mood changes, irritability, and anxiety can also occur. These symptoms typically start within a day or two of stopping, may peak in the first week or two, and can last a few weeks, especially with abrupt discontinuation, high doses, or longer treatment durations. The take-home is that discontinuation of SNRIs is associated with withdrawal symptoms, which is why gradual tapering rather than abrupt stopping is recommended. If needed, a slower taper or a cross-taper to a longer-acting agent can help mitigate these effects.
