How to Stop Hiccups After Steroid Injection

Steroid-induced hiccups are an uncommon but well-recognized side effect of corticosteroid injections, and they usually resolve on their own within a few days to about two weeks. That said, waiting them out can be miserable. There are physical techniques you can try at home for immediate relief, and if hiccups persist beyond 48 hours, prescription medications and steroid-switching strategies have helped in documented cases. The approach depends on how long the hiccups have been going, how disruptive they are, and what type of steroid was used.

Why Steroid Injections Trigger Hiccups

The hiccup reflex involves a loop between the brain and the diaphragm. Signals travel along the phrenic and vagus nerves to a poorly understood processing center somewhere between the brainstem and the upper spinal cord, then back out to the diaphragm and the muscles between the ribs, causing the characteristic involuntary spasm and “hic” sound. Several brain chemicals, including GABA and dopamine, play a role in this processing center.¹ Corticosteroids are thought to interfere with these signaling pathways, though the exact mechanism remains unclear. One theory is that steroids lower the threshold for triggering the hiccup reflex by affecting neurotransmitter activity in the central processor. Another is that the anti-inflammatory effects of steroids alter nerve sensitivity along the reflex arc.

Higher doses of systemic steroids are more commonly linked to hiccups, which partly explains why injections into a joint or the epidural space cause them less frequently than, say, intravenous dexamethasone given during chemotherapy. But “less frequently” does not mean never. Cases have been documented after epidural steroid injections, and at least one published report describes hiccups following a single intra-articular injection of betamethasone into the knee.² Even regional injections deliver some steroid into the systemic circulation, which is likely enough to flip the switch in susceptible people.

When They Start and How Long They Last

Hiccups triggered by steroids tend to begin relatively quickly after the injection. Published reports indicate onset anywhere from one hour to about 18 hours after the dose, and they can persist for one to nine days.³ Most cases in the medical literature fall somewhere in the middle of that range, resolving within a few days. In one detailed case following a cervical epidural steroid injection, the hiccups gradually decreased in frequency starting around day five and were completely gone by day 13.¹

If a patient is on an ongoing course of steroids rather than a one-time injection, the hiccups can last as long as the medication continues. One palliative care case documented severe, intermittent hiccups that persisted for the full 15 days a patient was on oral steroids, prompting multiple calls to the clinic and requests for appointments. The hiccups resolved shortly after discontinuing the medication.⁴ For a single injection, the steroid is already in your body and will be cleared naturally, so the timeline is more about waiting for the drug to wash out than making a decision about stopping it.

Who Gets Them

Not everyone who receives a steroid injection ends up hiccupping, and the side effect is genuinely uncommon. But certain factors seem to make it more likely. A large analysis of adverse drug event reports in Japan identified male sex as a significant risk factor for steroid-associated hiccups, along with greater height.⁵ Dexamethasone, one of the most potent corticosteroids, was the steroid most strongly linked to the problem. This matters because dexamethasone is also one of the steroids commonly used in epidural injections and in chemotherapy-related nausea protocols.

Why men seem more susceptible is not entirely clear. The hiccup reflex may have some hormonal component, or it may simply be that taller bodies have longer phrenic nerves with more opportunity for irritation. Regardless, if you are a man who has experienced steroid-induced hiccups before, the odds of it happening again with a future injection are higher, and that is worth mentioning to your doctor ahead of time so they can consider an alternative steroid formulation.

Physical Techniques You Can Try Right Away

Before reaching for a prescription, physical maneuvers are worth trying. The classic home remedies for hiccups all share a common principle: they attempt to interrupt the reflex arc by stimulating the vagus nerve or resetting the breathing pattern. Some are more effective than others, and one newer approach has actual data behind it.

A device called the Forced Inspiratory Suction and Swallow Tool, or FISST, works by having you sip water through a tube that requires strong suction. This simultaneously engages the phrenic nerve (through forceful inhalation), the vagus nerve (through swallowing), and increases parasympathetic tone. In a prospective study of 249 people with hiccups, this approach stopped them about 92% of the time.⁶ The device is commercially available and marketed under various brand names. That study included hiccups from various causes, not specifically steroid-induced ones, but since the physical reflex arc is the same regardless of the trigger, the mechanism of action applies.

If you do not have access to such a device, the underlying principle still works with improvised methods. Standard vagal maneuvers include:

• Breath holding: Take a deep breath and hold it for 10 to 20 seconds, then exhale slowly. This increases pressure on the diaphragm and stimulates the vagus nerve.
• Valsalva maneuver: Bear down as if you are trying to have a bowel movement while holding your breath. This generates the same kind of vagal stimulation.
• Ice water sipping: Drinking very cold water slowly can stimulate the vagus nerve where it passes near the esophagus.
• Swallowing granulated sugar: A teaspoon of dry sugar on the back of the tongue can irritate the pharynx enough to interrupt the reflex.

These techniques work best for hiccups that have just started. If you are already several hours in and nothing is working, the reflex loop may be too entrenched for vagal maneuvers alone to break it.

Prescription Medications That Have Worked

When hiccups persist beyond 48 hours, they are medically classified as “persistent,” and beyond a month, “intractable.” Steroid-induced hiccups rarely last that long, but they can easily cross the 48-hour mark and become disruptive enough to interfere with sleep, eating, and daily functioning. At that point, medication becomes reasonable.

Gabapentin has been used successfully in steroid-induced hiccups. In one published case of a patient who developed hiccups after steroid treatment for an eye condition, gabapentin resolved the problem.⁷ Gabapentin works on the central nervous system by modulating calcium channels, which may help quiet the overactive hiccup reflex center. It is already widely prescribed for nerve pain, so many doctors are comfortable with it.

Baclofen, a muscle relaxant that acts on GABA receptors, is another medication frequently mentioned in the hiccup literature. One case report describes its use for persistent hiccups following an epidural steroid injection.⁸ However, results are inconsistent. In another post-epidural case, baclofen was prescribed but failed to alleviate the hiccups.⁹ Similarly, in the cervical epidural case mentioned earlier, a combination of haloperidol, metoclopramide, and gabapentin given every eight hours did not improve the patient’s condition, and the hiccups ultimately resolved on their own by day 13.¹

This inconsistency is frustrating but honest. The medical literature on treating steroid-induced hiccups consists almost entirely of individual case reports, not controlled trials. What worked for one patient did not work for the next. The medications your doctor is most likely to try include gabapentin, baclofen, chlorpromazine (the only drug actually approved by the FDA for hiccups, though it carries more side effects), and metoclopramide. If one does not help, switching to another is standard practice.

Switching to a Different Steroid

For people who need ongoing steroid therapy and keep getting hiccups, one of the most effective documented strategies is switching to a different corticosteroid. Dexamethasone is the steroid most commonly associated with hiccups, and rotating to methylprednisolone or prednisolone has produced striking results in oncology settings. In a study of 40 chemotherapy patients with dexamethasone-induced hiccups, switching to methylprednisolone led to complete resolution in 85% of cases. The average hiccup duration dropped from over an hour per episode to under two minutes, and the intensity dropped dramatically as well, all without worsening nausea control.¹⁰

A similar approach was reported in a colorectal cancer patient whose chemotherapy-induced hiccups resolved after rotating from dexamethasone to prednisolone.¹¹ The reasoning here is straightforward: different steroids have slightly different chemical structures and receptor-binding profiles. Whatever it is about dexamethasone that triggers the hiccup reflex, methylprednisolone and prednisolone seem to do it far less often. If your hiccups followed a dexamethasone injection and you need another injection in the future, asking your doctor about using a different formulation is a practical conversation to have.

This option is most relevant for people on repeated steroid courses, such as chemotherapy patients or those receiving serial epidural injections for chronic pain. If you received a one-time injection and are dealing with hiccups now, the steroid is already in your system and cannot be swapped out. But the information is still useful for preventing recurrence.

When to Contact Your Doctor

Most steroid-induced hiccups are annoying rather than dangerous. But hiccups that start after a spinal or epidural injection specifically deserve a brief check-in with your provider, because the same nerve pathways that produce hiccups can also signal more serious complications. Clinicians evaluating post-injection hiccups are trained to rule out vertebral artery dissection, epidural hematoma, spinal cord infarction, and stroke, all of which can present with hiccups as an early symptom.¹² These complications are rare, but they are time-sensitive. If your hiccups come with a severe headache, neck stiffness, weakness or numbness in your arms or legs, difficulty speaking, or any other neurological symptoms, seek care immediately.

Even without alarming symptoms, hiccups lasting more than 48 hours are worth reporting to your doctor’s office. Persistent hiccups can interfere with sleep and eating enough to cause real distress, as documented in the palliative care case where a patient made multiple clinic calls over the course of two weeks trying to get relief.⁴ You do not need to suffer through it silently. Your provider can prescribe a trial of gabapentin or another medication and, if relevant, adjust your steroid regimen for future treatments.

What to Expect If You Have Had Them Before

Steroid-induced hiccups tend to recur. If you developed hiccups after one injection and receive the same steroid again, there is a good chance the hiccups will return. This recurrence pattern is described across multiple case reports and is consistent with the idea that some individuals have a lower threshold for steroid-triggered activation of the hiccup reflex. The practical takeaway is that your history matters. Let your treating physician know before any future steroid injection that you have experienced this side effect. In many cases, the steroid can be changed to one less associated with hiccups, the dose can be adjusted, or a preemptive prescription for gabapentin or baclofen can be arranged.

It is also worth knowing that the side effect is underreported. Because hiccups are not considered a serious adverse event, many patients and providers do not formally document them. The published case literature likely represents a fraction of actual occurrences. If your doctor seems surprised to hear that your injection caused hiccups, it does not mean you are imagining things or that the connection is dubious. The association between corticosteroids and hiccups is well established in pharmacology; it is just that most clinicians who do not work in oncology encounter it infrequently.

Acupuncture and Other Complementary Approaches

For persistent or intractable hiccups that resist standard treatments, a few complementary therapies have been studied, though the evidence base is thin. Near-infrared light therapy applied to acupuncture points was tested in a group of 34 patients with intractable hiccups from various causes, and all but one experienced complete resolution within a few days of starting treatment.¹³ The results were impressive, but this was a single study without a control group, and the hiccups had various causes rather than being specifically steroid-induced. Traditional acupuncture and acupressure have also been reported anecdotally to help with hiccups, though controlled evidence is similarly limited.

Digital rectal massage is another vagal stimulation technique that has appeared in the medical literature as a last-resort maneuver for intractable hiccups. It works on the same principle as the gentler vagal maneuvers described earlier, just more aggressively. This is not something to try on your own; it appears in the literature as a physician-performed intervention for hospitalized patients who have exhausted other options. For most people dealing with post-injection hiccups, the physical techniques and, if needed, a short course of gabapentin will be more than sufficient before anything this extreme becomes relevant.
