Persistent hiccups are described as a recurring troublesome series of involuntary inspirations accompanied by glottic closure, lasting longer than a month. Recently, baclofen, the most effective treatment for intractable hiccups was found to be a useful drug for the management of chronic hiccups, and that substituting gabapentin for baclofen can be effective. Moreover, gabapentin was used successfully in combination with baclofen. We report here on three patients with persistent hiccups, where gabapentin was used successfully as an "add-on" with baclofen.
