The fastest way to prevent seasickness is to start medication or a patch before you board

Seasickness happens when your inner ear, eyes, and body sense conflicting motion signals. The most effective prevention is dramamine (dimenhydrinate) or bonine (meclizine), both sold over the counter at any pharmacy. Take dramamine every four to six hours starting the day before you sail, or bonine once daily the night before departure. Both work better as prevention than as a cure once nausea starts.

A scopolamine patch (brand name Transderm Scop) is stronger but requires a prescription from your doctor. You explore it behind your ear four hours before boarding, and it lasts three days. The patch works for about 70 percent of people who get seasick, compared to 50 to 60 percent for oral medication. Ask your doctor about it at least two weeks before your cruise, since the prescription takes time.

Ginger supplements and acupressure wristbands (Sea-Bands) have weak evidence behind them, but they carry no side effects and cost under $15. Some people find them useful as a backup to medication or on calmer days when you might not need the full dose.

Key Takeaways

  • Start dramamine or bonine the day before you board, not after you feel sick, because prevention works much better than treatment.
  • A scopolamine patch prescribed by your doctor is the strongest option and lasts the entire first three days of your cruise.
  • Choose a cabin in the middle of the ship on a lower deck, where motion is least noticeable.
  • Eat small meals, stay hydrated, and spend time on deck looking at the horizon rather than at the moving ship or your phone.
  • If medication makes you drowsy, take it at night or ask your doctor about non-drowsy alternatives.

Where to sleep and sit to feel less motion

The middle of the ship moves less than the front or back. Book a cabin on deck 4, 5, or 6 if your cruise line lets you choose, rather than the top decks or the very bottom. The higher you are, the more you feel the ship's rocking. The lower you are, the more you feel the engine vibration and the ship's pitch.

Spend your days on the open deck, especially the middle sections, rather than in your cabin or the interior of the ship. Looking at the horizon helps your brain reconcile the motion your inner ear is sensing. Sitting in a cabin or a windowless dining room makes seasickness worse because your eyes see a stationary room while your body feels movement.

If rough seas hit during your cruise, stay in your cabin and lie flat rather than sitting up. Lying down reduces the conflicting signals between your inner ear and your eyes. Avoid reading, scrolling your phone, or watching screens, which can trigger nausea even if you were not feeling sick before.

Food and drink choices that reduce nausea

Eat small, frequent meals rather than three large ones. A full stomach makes seasickness worse. Stick to bland foods: crackers, toast, plain rice, chicken, and fruit. Avoid greasy, spicy, and heavy foods, which sit in your stomach and worsen nausea.

Drink plenty of water and electrolyte drinks like coconut water or sports drinks. Dehydration makes seasickness worse. Avoid alcohol and caffeine on the first day or two of your cruise, even though the bar is open. Both dehydrate you and can trigger nausea in combination with ship motion.

Ginger tea or ginger ale may help some people, though the evidence is mixed. Peppermint tea can also calm your stomach. These are low-cost additions to your medication plan and do not interact with dramamine or bonine.

What to do if seasickness starts despite prevention

If you feel nauseous even after taking medication, go to the ship's medical center. They can give you an injection of stronger medication or an IV if you are severely dehydrated. Most cruise ships have a doctor and nurse on staff, and the visit is usually included in your cruise fare or costs $50 to $100.

Do not wait until you are vomiting to seek help. Nausea that lasts more than a few hours can lead to dehydration, which makes everything worse. The ship's medical staff can also tell you whether to take another dose of your medication or switch to something different.

If you are stuck in your cabin feeling terrible, ask room service to bring you crackers, ginger ale, and water. Keep the cabin cool and dark. Open a window or porthole if you have one, because fresh air and a view of the horizon can help even from bed.

Medication side effects and how to manage them

Dramamine and bonine both cause drowsiness in many people. If you take dramamine during the day, you may sleep through the activities you paid for. Take it at night instead, or ask your doctor about dramamine non-drowsy, which contains a different active ingredient (cyclizine) and causes less sleepiness.

Bonine causes less drowsiness than dramamine for most people, so if you are sensitive to medication side effects, start with bonine. Both can cause dry mouth and blurred vision in some users. These side effects usually fade after a day or two as your body adjusts.

The scopolamine patch can cause dry mouth, blurred vision, and in rare cases, confusion or hallucinations. It is not safe if you have glaucoma or certain heart conditions, which is why you need a prescription. Tell your doctor about any other medications you take, because the patch can interact with some drugs.

When seasickness is a sign you should not cruise

Some people get severe seasickness no matter what they take. If you have had motion sickness in cars, planes, or amusement park rides, you are at higher risk. Talk to your doctor before booking a cruise, not after. They can help you decide whether medication will work for you or whether a cruise is not the right vacation choice.

If you have a history of severe nausea or vomiting, or if you take medications that interact with seasickness drugs, your doctor may recommend a different type of vacation. There is no shame in that. A land-based resort or a river cruise (which moves more slowly and smoothly) might be better options.

If you have already booked and are worried, ask your cruise line about their cancellation policy. Many lines allow you to cancel or rebook up to a certain number of days before departure if you have a medical reason. Some also offer travel insurance that covers cancellation for medical reasons.

Frequently Asked Questions

Can I take dramamine and bonine together?

No. Both contain similar active ingredients and taking them together can cause overdose symptoms like extreme drowsiness, confusion, or rapid heartbeat. Pick one and stick with it. If one is not working after a full day, stop it and switch to the other, but do not combine them.

Will seasickness medication make me too drowsy to enjoy my cruise?

Dramamine often does, but bonine causes less drowsiness for most people. If you are sensitive to medication, take dramamine at night and use bonine during the day, or ask your doctor about the non-drowsy version. Many people find that after the first day or two, their body adjusts and drowsiness decreases.

Is the scopolamine patch worth the cost and prescription?

If you get severe seasickness or if oral medication has not worked for you before, yes. The patch is more expensive than over-the-counter pills but works for more people and lasts longer. If you have mild seasickness or have never tried medication, start with dramamine or bonine first.

What if I forget to take my medication before boarding?

Take it as soon as you remember, even if you are already on the ship. Medication works better as prevention, but it can still reduce nausea if you take it within the first few hours after boarding. If you are already feeling sick, go to the ship's medical center instead of trying to catch up with missed doses.

Do I need to tell the cruise line I get seasick?

You do not have to, but if you are severely affected, let them know when you board. They can note it in your file, and the medical staff will be prepared if you need help. You can also request a cabin in the middle of the ship when you book, which many lines allow without extra charge.
