Some individuals prefer to use only an SSRI. However, almost all SSRI have the ability to induce sexual dysfunction. Recently Fluvoxamine (luvox) has been speculated to help individuals with sexual dysfunction. At present Luxol is used to treat OCD and does work well. The drug does maintain sexual function but it has two side effects of concern. When the drug is abruptly discontinued, it can cause withdrawal symptoms of dizziness, fatigue, nausea, vivid dreams, irritability, and headaches. The other problem is that luvox may increase the risk of suicide in young adults and children. Individuals who are depressed have been found to have worsening of depression and suicidal thoughts when taking Luvox. Therefore, at the moment, the drug is rarely prescribed without close supervision.
Some physicians do try an add a psychostimulant to the patient’s regimen to counter the sexual dysfunction. Addition of drugs like Ritalin or methyl phenidate have been shown to work, but often the side effects of anxiety and insomnia also dominate. Further, these drugs have ability to cause physical dependence and cause withdrawal reactions when the drugs are abruptly stopped.
The latest and perhaps the one with the least controversy are Viagra and Tadalafil. Since the availability of Viagra and related drugs, there have been a few studies to see if the sexual dysfunction can be reversed. There have been a few studies which showed that both tadalafil and sildenfail both slightly improved sexual function in individuals who took anti depressants. However, most of the studies included small numbers and long-term data are not available. Anecdotal reports indicate that while Viagra does work, the effects are not sustained in the long run. In any case, Viagra is perhaps the best option for individuals with sexual dysfunction which occurs with anti depressants. The few negatives about viagra are that it is expensive and fake/counterfeit products are common.
