You need to be able to eat, drink, and sleep in order to function and stay healthy. In rare cases, hiccups can prevent you from doing these things. If this happens to you, then you need to see your doctor immediately so that you can get relief. Your hiccups shouldn't be interfering with your daily life. Although most hiccups go away on their own within a few hours, sometimes an underlying condition can make the hiccups continue. Your doctor can determine what’s causing your hiccups and treat them. Tell your doctor how long your hiccups have been happening, as well as any other symptoms you’re having. If you have hiccups that won’t go away, your doctor might prescribe a treatment. However, medication isn’t right for everyone, so your doctor will talk to you about the risks and benefits. They may prescribe one of the following medications:  Chlorpromazine (Thorazine) is one of the most widely used medications for hiccups, and it is suitable for short-term therapy. Metoclopramide (Reglan) is a drug most commonly used for nausea, but it works for hiccups as well. Baclofen is a muscle relaxant which can treat hiccups.
