If an SSRI causes side effects but is clinically effective, what is the recommended approach?

• A. Use a different SSRI, stay in the same class
• B. Stop treatment and switch to SNRI
• C. Add MAOI
• D. Switch to a TCA

Answer: (A)

When an SSRI is clinically effective but the patient cannot tolerate the side effects, the best approach is to switch to a different SSRI within the same class. Different SSRIs can have distinct tolerability profiles, so a patient who responds to one may experience fewer or different side effects with another. This preserves the antidepressant efficacy while potentially improving tolerability.

In practice, you don’t abandon the therapeutic benefit or jump to a different class right away. You transition carefully—start the new SSRI at a low dose and either cross-titrate or taper the old one to minimize withdrawal or serotonin syndrome. The goal is to maintain response with a more tolerable side-effect experience.

Choosing a different SSRI is preferred over stopping treatment and moving to an SNRI, adding an MAOI, or switching to a TCA because those options tend to carry higher risk, more challenging side-effect profiles, or less predictable maintenance of the established therapeutic response.
