How to Get Rid of Hiccups

7. When Hiccups Become Too Much

If your hiccups last more than a few hours, you should see a doctor. Once your hiccups exceed 3 to 4 hours, they’ve likely become chronic and/or persistent. That’s when you know it’s time to get some medical help. If the hiccups have only lasted 3 or so hours, a doctor may recommend you wait it out. Once they reach the 24-hour mark though, doctors can provide you with medication to help. Chlorpromazine, baclofen, and phenytoin are the most common prescription medications doctors will prescribe for persistent hiccups.
