Can You Take Fluoxetine with Omega-3?

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for depression and anxiety, while Omega-3 fatty acids are often taken for various health benefits, including immune support. The combination of these two substances does not have well-documented interactions, but caution is advised due to the potential for increased bleeding risk and serotonin syndrome, particularly at higher doses of Omega-3. It is essential to consult a healthcare provider before starting this combination.
