Nausea & Vomiting
Nausea & Vomiting
US shipping from Canada supports access to Nausea and vomiting medications that help manage upset stomach, queasiness, and vomiting from many causes, including infections, migraine, medication side effects, and travel. This category focuses on symptom control and comfort, and it may include antiemetics (medicines that help prevent nausea and vomiting), plus a few digestive support options that address related triggers like reflux or slow stomach emptying. You can compare brands, dosage forms, and strengths, including tablets, orally disintegrating tablets, liquids, and patches, while keeping in mind that stock and package sizes can change without notice.
What’s in This Category
This category groups products that target nausea, vomiting, and the “sick to the stomach” feeling. Some options work in the brain’s vomiting center, while others calm inner-ear signals that drive dizziness. Shoppers often browse by likely cause, such as travel, viral stomach illness, or migraine-related nausea. For broader background, see the nausea causes and treatments guide when symptoms feel new or confusing.
Many items here are antiemetic medications, including serotonin (5-HT3) blockers, dopamine blockers, antihistamines, and anticholinergics. These groups can reduce nausea but differ in sedation, constipation, and movement-related side effects. Some products fit short, predictable triggers like Motion Sickness, while others support ongoing needs linked to chronic conditions. For a plain-language overview of common symptom patterns, MedlinePlus provides a neutral summary on causes and care basics for nausea and vomiting.
Forms matter as much as ingredients. Tablets and capsules suit routine dosing, while orally disintegrating options help when swallowing is hard. Liquids can allow more flexible dosing, but they may need careful measuring. Patches can help during travel, though they require steady skin contact and simple handling.
How to Choose Nausea and vomiting medications
Start by matching the product to the most likely trigger and time course. Vestibular nausea often comes from travel or vertigo and may respond to sedating antihistamines or anticholinergic options. Stomach-related nausea can follow infections, reflux, or medications, and it may call for different mechanisms. If vomiting is frequent, consider a form that stays down, such as dissolving tablets.
Next, compare onset, duration, and side-effect profile. Some options cause drowsiness and dry mouth, which can affect driving or shift work. Others can cause restlessness or muscle stiffness in sensitive people, especially with higher doses. For label-based safety details and warnings, use FDA labeling references through Drugs@FDA drug information and labels when reviewing specific ingredients.
Also check practical handling needs before selecting a form. Patches need clean, dry skin and steady placement for best adhesion. Dissolving tablets can be easier during active nausea, but they still require careful storage. If dehydration is a concern, prioritize hydration support and seek care for persistent vomiting.
Common mistake: picking a sedating option for daytime work demands.
Common mistake: doubling doses after vomiting without a clinician’s plan.
Common mistake: ignoring interactions with alcohol, sleep aids, or opioids.
Popular Options
This category includes both familiar generics and well-known products used in clinics. Some over the counter antiemetics focus on motion-related nausea and short-term stomach upset. Others require a prescription because they act on stronger central pathways. Product pages can help compare strengths, forms, and counseling notes.
ondansetron (Zofran) is a 5-HT3 blocker often used for severe nausea, including after surgery or certain medications. It is usually non-sedating, which can suit daytime use. Clinicians still watch for constipation and heart rhythm risks in higher-risk patients. Another option, metoclopramide, may help when nausea links to slow stomach emptying, but it needs careful attention to movement-related side effects.
For travel and dizziness patterns, dimenhydrinate (Dramamine) can help, though it often causes sleepiness and dry mouth. A scopolamine patch supports longer trips, but it can blur vision or worsen glaucoma risk in some people. For pregnancy-related symptoms, doxylamine-pyridoxine is commonly used under clinician guidance, especially when lifestyle steps are not enough. If dizziness drives nausea, meclizine is another vestibular-focused option that can still cause sedation.
Related Conditions & Uses
Nausea rarely appears alone, so this category connects to several common conditions. Travel triggers often involve inner-ear signaling, so motion and dizziness resources can guide product selection and expectations. Migraine can also cause intense nausea, even without severe head pain. See the Migraine page for related symptom patterns and treatment pathways.
Digestive triggers matter, especially when nausea follows meals or worsens when lying down. Reflux can mimic “stomach flu” early, and it can aggravate queasiness over weeks. The Acid Reflux page can help frame symptoms that point toward burning, regurgitation, or chronic irritation. In short-term infections, nausea often improves as hydration and intake stabilize.
Some people need prescription antiemetics because symptoms are severe, predictable, or tied to medical treatments. These options can be important for chemotherapy, post-operative recovery, and certain neurologic conditions. They also require extra screening for interactions and contraindications. If vomiting lasts more than a day, or dehydration signs appear, medical evaluation matters.

Frequently Asked Questions
Do I need a prescription for nausea and vomiting products?
Some products require a prescription because they have stronger effects or higher risk profiles. Prescription status depends on the specific ingredient, strength, and country rules. Many motion-sickness options are non-prescription, while some central antiemetics are prescription-only. Product pages typically note whether an item is Rx or non-Rx. If you are unsure which category applies, confirm with a pharmacist or prescriber before ordering.
Can these items ship to the United States?
Many items can ship to the United States, but eligibility depends on the product type and destination rules. Some medications face extra restrictions based on controlled status, temperature handling, or documentation needs. Shipping options and limitations can vary by state and by product. Review each item’s shipping notes before checkout. If a product cannot ship to a location, a similar alternative may still be available.
What should I compare when browsing anti-nausea options?
Compare the likely cause of symptoms, the dosage form, and the side-effect profile first. Sedation risk matters for travel days, work shifts, and driving. Onset and duration matter for short triggers versus longer recovery periods. Also compare strengths and package sizes, since they can affect dosing convenience. If vomiting makes swallowing difficult, consider forms designed to dissolve or stay down better.
How do I know if nausea is from motion, migraine, or stomach illness?
Patterns often give the best clue. Motion-related nausea usually starts with travel or head movement and may include dizziness. Migraine-related nausea often comes with light sensitivity, sound sensitivity, or head pressure. Stomach illness may include diarrhea, fever, or sick contacts, and symptoms can change across a day. If symptoms are severe, persistent, or include dehydration signs, clinical assessment helps clarify the cause.
What are common reasons an item shows out of stock?
Stock can change due to manufacturer supply, packaging updates, and demand spikes during travel or illness seasons. Some strengths and dosage forms are more affected than others. Cross-border fulfillment can also limit certain items temporarily due to documentation or handling requirements. When one strength is unavailable, a different strength or form may still be listed. Checking comparable products in the same class can help keep options open.
