Why Do Nicotine Pouches Give You Hiccups? (And How to Stop Them)

By PouchGuide Editorial Team · Published September 25, 2026

You put in a pouch, and a few minutes later the hiccups start. It’s common enough that “ZYN hiccups” is its own search term, and people who’ve never had it are often baffled. The good news is that it’s a known, usually harmless side effect of nicotine taken by mouth. And it’s mostly preventable.

Why nicotine causes hiccups

Hiccups are sudden, involuntary contractions of the diaphragm, the muscle under your lungs. Anything that irritates the nerves and muscles around your esophagus and stomach can set them off.

With nicotine pouches, the main suspects are:

• Swallowing nicotine-laced saliva. A pouch releases nicotine into your saliva. Some is absorbed through your gums, but some gets swallowed, where it can irritate your esophagus and stomach.
• Too much nicotine at once. A strong pouch, or one straight after another, delivers a lot of nicotine quickly.
• Being new to it. People with low nicotine tolerance tend to notice side effects more.

The same effect is well documented for nicotine medicines taken by mouth. The US National Library of Medicine’s MedlinePlus drug guides warn that using nicotine lozenges “one after another can cause side effects such as hiccups, heartburn, and nausea”, and that chewing nicotine gum continuously “may cause hiccups, heartburn, nausea, or other side effects”.

How common is it?

Clinical trial data gives a rough idea:

• In a nicotine lozenge trial (NCT01466361), 6 of 52 people (about 12%) using the 4mg lozenge reported hiccups. That compares with none of the 60 using the 1.5mg lozenge, and none on placebo.
• In a nicotine pouch trial of on! pouches (NCT05664672), 1 of 28 people in the 2mg group reported hiccups, with none in the 4mg or 8mg groups.

The lozenge trial points to a dose effect: hiccups showed up at 4mg but not at 1.5mg. The pouch trial is too small to show any pattern, since one case in one group could be chance. Either way, hiccups affect a minority of users, not everyone.

How to stop nicotine pouch hiccups

If you have them now:

• Take the pouch out. This removes the source, and the hiccups usually settle within minutes.
• Try standard hiccup remedies. The NHS suggests sipping ice-cold water, holding your breath for a short time, breathing into a paper bag (never over your head), pulling your knees to your chest and leaning forward, or swallowing a little granulated sugar.
• Avoid fizzy drinks and alcohol for a while. The NHS lists these among things that can make hiccups worse.

To prevent them next time:

1. Don’t swallow the juice. Let saliva pool and swallow less often, or spit discreetly if you can. Our guide to using pouches correctly covers placement and technique.
2. Drop a strength. This is the single biggest fix for most people. If 6mg or higher gives you hiccups, try a lower strength. See our strength guide.
3. Don’t chain pouches. Leave a gap between pouches rather than putting a new one straight in.
4. Try the upper lip. Some users find they swallow less saliva with the pouch under the upper lip rather than the lower.
5. Try a drier pouch. Moist pouches can release nicotine faster (see dry vs moist pouches).
6. Avoid using a pouch right after fizzy drinks or alcohol, which the NHS lists as hiccup triggers.

When hiccups are a sign of too much nicotine

On their own, hiccups aren’t dangerous. But if they come with nausea, dizziness, sweating, a racing heart or vomiting, you’ve probably had too much nicotine. Take the pouch out and don’t use another for a while. Our side effects guide explains which symptoms are normal and which are warning signs.

See a doctor if hiccups last longer than 48 hours or keep coming back and affect your life. The NHS gives these as reasons to seek medical advice. Get urgent help for severe symptoms such as chest pain, fainting or confusion.

Bottom line

Nicotine pouch hiccups are a known side effect of taking nicotine by mouth, mostly caused by swallowing nicotine-laced saliva and by strong doses. In a nicotine lozenge trial, hiccups appeared at 4mg but not at 1.5mg. Take the pouch out to stop them, and prevent them by swallowing less, dropping a strength and spacing out pouches. If they come with nausea or a racing heart, that’s a sign you’ve had too much nicotine.
