Most of the commonly prescribed antidepressants have sexual side-effects. These side-effects may include decreased libido, erectile dysfunction, delayed ejaculation or anorgasmia. Generally, sexual side-effects persist throughout the course of treatment, although some patients may rarely develop a tolerance to the drugs. Wellbutrin (bupropion), Serzone (nefazodone) and Remeron (mirtazapine) are the least likely to cause sexual side-effects. Strategies for countering sexual side-effects include:
- Schedule your daily dose so that you are taking it right after you would generally engage in sexual activity.
- Talk with your doctor about switching to a medication with a lower risk of sexual side-effects.
- Talk with your doctor about lowering your dose.
- Talk with your doctor about taking a medication to counteract sexual side-effects, such as Viagra (sildenafil) or Yocon (yohimbine).
- Talk with your doctor about taking a "drug holiday" (stopping medication for a day or two prior to sexual activity).
