Fluvoxamine (Luvox) is an FDA approved medication for treatment of obsessive-compulsive disorders. Some doctors may also prescribe this medication for other psychiatric conditions. While fluvoxamine is effective in treating these disorders, it has been associated with sexual problems.
Fluvoxamine is one of a class of drugs called selective serotonin reuptake inhibitors or SSRIs. These medications work by increasing the activity of the brain chemical serotonin, which helps regulate mood.
It is not yet clear how SSRIs affect sexual function. The effects are believed to be related to the increased level of serotonin, which may affect sexual reflex centers.
As you adjust to your new medication, the sexual side effects may go away.
This tactic may work, but carries the risk of a relapse of the depression or disorder. Never change your dosage without checking with your doctor first.
Since the medical response to SSRIs can vary among people, your doctor will consider the severity of your condition, as well as your response to the drug before switching to another medication. When switching is appropriate, some options include:
This involves maintaining your current level of fluvoxamine, while adding a second medication to offset the sexual side effects. This option is generally less desirable since antidotes frequently have their own side effects and may adversely interact with the primary medication you are taking. However, certain options do exist.
Sildenafil (Viagra) and related drugs may be helpful for men with sexual side effects of SSRIs. Bupropion also has been shown to benefit men with sexual dysfunction due to taking SSRIs. Amantadine has been used, but studies have not proven that it is beneficial.
This involves taking your usual Thursday morning dose and then nothing again until noon on Sunday, when you resume your previous schedule.
There is a risk with this technique that you may feel well enough during the short drug holiday to discontinue your medication all together, which can lead to a relapse. Also there is a risk of having some withdrawal symptoms from abruptly stopping your medication. Make sure you discuss this option with your doctor before trying it.
The efficacy of herbal supplements to treat the sexual side effects of SSRIs is not clear. Care should also be taken with herbal products because they are not strictly regulated as drugs are. One herb commonly used to resolve the sexual dysfunction associated with SSRIs is yohimbine. More studies are needed to determine the effectiveness and safety of this remedy. Be sure that you talk to your doctor before taking any herbs or supplements. They could react with medications that you are currently taking.
