Key takeaways
Fluvoxamine and paroxetine (Paxil) are both selective serotonin reuptake inhibitors (SSRIs) but are used for different conditions. Fluvoxamine is primarily prescribed for obsessive-compulsive disorder (OCD) and is available only in generic form. It can be taken once or twice daily, depending on the formulation. Paroxetine, on the other hand, is used for a broader range of conditions including depression, various anxiety disorders, post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder. It is available in both brand name (Paxil) and generic forms, and is typically taken once daily. Fluvoxamine is more likely to cause side effects like nausea and sleep problems, and it has a higher risk of drug interactions. Paroxetine can also cause side effects such as weight gain and sexual problems, and it may lead to withdrawal symptoms if stopped abruptly. Both medications can increase the risk of suicidal thoughts in people under 25 and should not be mixed with alcohol.
