Feeling queasy on boats, planes, cars or theme park rides is very common. Motion sickness (including seasickness) has been recognised for centuries and affects people of all ages.
For some, it’s a mild inconvenience. For others, it can spoil holidays, cruises or fishing trips altogether. The good news is there are ways to help manage symptoms so you can feel more comfortable when travelling.
Motion sickness happens when the signals from your eyes, inner ears and muscles don’t match. For example:
When your brain receives these mixed messages, it can trigger symptoms of motion sickness.
Your inner ear (vestibular system) plays a big role in balance, but your brain also takes information from your eyes, skin and muscles. When these messages conflict for long enough, motion sickness can result.
Anyone can experience motion sickness, but it tends to be more common in:
It’s not contagious and often improves once the motion stops.
Motion or seasickness can come on quickly and may include:
Symptoms usually settle once the movement stops, but for some people they can linger for a short time afterwards.
For many people, symptoms improve as their body adapts to the movement. Some strategies that may help include:
Always stop what you’re doing and sit or lie down if you feel very unwell.
Some people report benefit from non-medicine options such as:
Evidence for these options is mixed and they don’t work for everyone, but they may be worth discussing with your doctor or pharmacist as part of a wider plan.
If motion sickness is frequent or severe, your doctor or pharmacist may recommend medicines that are specifically used for motion-related nausea and dizziness.
These medicines are usually taken before travel (for example, a couple of hours before a boat, plane or car trip) and may help reduce the likelihood or severity of symptoms in some people. Like all medicines, they can cause side effects such as drowsiness or dry mouth, and they are not suitable for everyone.

When it comes to effective sea sickness medication, not all tablets are equal. NCC compounds prescription sea sickness medication using pharmaceutical-grade active ingredients, including hyoscine (scopolamine) and promethazine, two of the most clinically proven options for preventing motion sickness. Because our formulations are compounded to prescription, doses can be tailored precisely for adults and children, giving you the right amount for your body weight and trip length rather than a one-size-fits-all over-the-counter option.
ea sickness tablets work by acting on the vestibular system, the part of the inner ear responsible for balance and spatial orientation. When the brain receives conflicting signals from the eyes and the vestibular system during motion, the result is nausea. Antihistamines and anticholinergics (the active ingredients in most sea sickness medications) reduce the intensity of these conflicting signals, preventing the nausea response before it starts.Not all tablets work the same way for every person. If you’ve tried one type without success, a different formulation or active ingredient may work better for you. Read our guide on why some sea sickness tablets work for some people but not others.
Standard over-the-counter sea sickness tablets come in fixed doses and limited forms, which works for many people but not all. Compounded sea sickness medication from NCC offers several advantages that OTC products simply can’t match. Children require significantly lower doses than adults, and compounding allows those doses to be prepared with precision rather than relying on tablet splitting or guesswork. For patients who experience nausea before they can even swallow a tablet, alternative delivery forms such as transdermal preparations or dissolving formulations can be compounded instead. NCC can also prepare combination formulations and flavoured options for younger patients, making treatment easier to take and more likely to work.
Both oral tablets and transdermal scopolamine patches are effective for sea sickness, but they suit different trips and different people. Patches are applied to the skin behind the ear and have a slower onset, typically 4–8 hours before protection begins, but they provide longer, more consistent coverage over multiple days, making them the better choice for extended voyages. Tablets act faster, usually within 30–60 minutes, and are well suited to day trips or shorter crossings where you need quick onset without a prolonged commitment. NCC can compound both forms, so your medication can be matched to the length and nature of your trip.
One of the most common reasons sea sickness tablets fail to work is simply that they were taken too late. Most oral sea sickness tablets need to be taken 30–60 minutes before boarding to allow the active ingredient to reach effective levels before motion begins. Transdermal patches require even more lead time, typically 4–8 hours before departure, so they need to be applied the evening before an early morning departure. Taking medication after nausea has already started is far less effective, as the vestibular response is already underway.
Yes. While some basic sea sickness medications are available over the counter, stronger formulations and combination compounds require a prescription from your GP or specialist. A prescription also allows NCC to compound your medication at the dose and delivery form most appropriate for you. Once your prescription is issued, NCC can fill it and ship directly to you anywhere in Australia.
No, individual response to sea sickness medication varies considerably. Factors including the active ingredient, the dose, the delivery form, and the individual’s physiology all influence how effective a given tablet will be. If you’ve tried standard OTC medication without success, a compounded alternative with a different active ingredient or a higher prescribed dose may produce better results. Read our full guide on why sea sickness tablets work better for some people than others.
Dosage is the critical consideration for children. Many standard adult sea sickness tablets are too strong for children, and tablet splitting is an unreliable way to achieve an accurate paediatric dose. Compounding allows child-appropriate doses to be prepared precisely, in formulations that are easier for children to take. Always confirm with your child’s GP or paediatrician before starting any sea sickness medication.
Some sea sickness medications are considered relatively safe under medical supervision during pregnancy, but this is a decision that must be made with your GP. Certain active ingredients are not recommended during pregnancy, and the risk-benefit assessment will depend on your individual circumstances and stage of pregnancy. Never start any new medication during pregnancy without first consulting your doctor.
