Why does nicotine gum give you hiccups?

You chewed too fast, or you used one piece after another. That is the label’s own explanation.

The label ties hiccups to how you chew. No study that we found explains the mechanism. In a 12-week trial, 6.6% of people on 4 mg gum got hiccups.

If you chew too fast, or do not chew correctly, you may get hiccups, heartburn, or other stomach problems.

How do you stop hiccups from nicotine gum?

Chew slowly until it tingles, then park the gum between your cheek and gum. Chew again when the tingle fades.

Chew a few times until you taste pepper or feel a tingle.
Park the piece in your cheek for about a minute.
Chew again when the tingle is gone.
Stop after about 30 minutes.

These steps are the directions on the label. It calls the method chew and park.

Why does nicotine gum burn your throat or taste peppery?

The peppery taste is the nicotine. The label treats it as your signal to stop chewing.

The gum contains buffers that make your saliva mildly alkaline, which helps nicotine pass into the mouth lining. When you taste pepper, the label tells you to stop chewing and park the piece.

Why does nicotine gum cause nausea or heartburn?

The label lists both with hiccups, as a result of chewing too fast. In one trial, 16% of people on 4 mg gum reported nausea.

Nausea with vomiting, dizziness, weakness and a fast heartbeat is how the label describes an overdose. Stop and get help if those come together.

Does coffee or soda make it worse?

Coffee and cola make the gum work less well. The label says not to eat or drink for 15 minutes before a piece, or during it.

A study had people rinse with coffee or cola between chews. Both made the mouth more acidic and cut the nicotine absorbed. Water did not. So gum with a coffee wastes part of the piece.

Are some gums less likely to cause hiccups?

No trial has compared flavors, coatings or strengths on hiccups. A lower dose is the reasonable bet.

In the one trial with numbers, a 4 mg lozenge caused more hiccups than a 4 mg gum: 10.7% against 6.6%.

When should you stop and ask a doctor?

Stop if you get mouth, teeth or jaw problems, an irregular heartbeat, signs of overdose or an allergic reaction.

Ask a doctor before you start if you have heart disease, high blood pressure that is not controlled, a stomach ulcer, diabetes or a history of seizures.

Is it bad to swallow nicotine gum?

The label has no warning about an adult who swallows a piece. It does warn that a used piece can make a child or a pet sick.

Wrap a used piece in paper and put it in the trash. US Poison Control is on 1-800-222-1222.
