Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs are the most commonly prescribed antidepressants for Parkinson’s-related depression because of their tolerability. These medications can also used to treat anxiety and obsessive-compulsive disorder (OCD). It often takes four to six weeks of a therapeutic dose for full effect. SSRIs are sometimes combined with other medications such SNRIs and TCAs (see tables below), but such combinations should be used with caution due to a potential for serotonin syndrome. Possible side effects include headache, nausea, insomnia, jitteriness, sexual dysfunction, and weight gain.
