Bring all prescription medications plus a full OTC kit — motion sickness remedies, antidiarrheal, pain relievers, antacids, and antihistamines at minimum. Onboard ship pharmacies charge $15–$40 per OTC item and $50–$150+ to see the ship's doctor, so packing right saves real money.

The ship's medical center will happily treat you — at $150–$300 per visit before any tests or prescriptions. That's the real reason your medication packing list matters: it's not just health, it's financial self-defense.
The Core Medication List (and What It Costs to Forget Each One)
Every cruise passenger should walk aboard with two categories covered: prescription medications (whatever you already take) and a personal OTC kit for the predictable problems cruising creates — motion sickness, traveler's diarrhea, sun exposure, minor injuries, and tropical bug bites.
Here's what to pack, why, and what you'll pay if you forget it and need it onboard:
| Medication / Item | Why You Need It on a Cruise | Ship Pharmacy Price (if forgotten) | Bring From Home |
|---|---|---|---|
| All prescription medications | No exceptions — bring 2x supply | Not available or $80–$200+ | Yes, in original bottles |
| Motion sickness (Meclizine / Dramamine / Bonine) | Open ocean = rough seas, especially day 1–2 | $18–$30 for small pack | Yes |
| Scopolamine patch (Rx) | Best option for severe sufferers | Requires onboard doctor visit ($150+) | Get from your doctor pre-trip |
| Antidiarrheal (Imodium / loperamide) | New food, new water, buffet exposure | $15–$25 | Yes |
| Antacid (Tums, Pepcid, omeprazole) | Cruise food = rich food, all day | $12–$22 | Yes |
| Pain reliever (ibuprofen or acetaminophen) | Sunburn, headache, overexertion | $14–$28 | Yes |
| Antihistamine (Benadryl / Zyrtec / Claritin) | Allergic reactions, bug bites, itching | $16–$30 | Yes |
| Hydrocortisone cream | Bug bites, rashes, heat rash | $14–$20 | Yes |
| After-sun / aloe vera gel | Sunburn relief | $18–$35 | Yes |
| Sunscreen (SPF 50+) | Caribbean sun is no joke | $22–$45 per bottle | Yes — bring 2 |
| Antibacterial ointment (Neosporin) | Cuts, scrapes from shore excursions | $12–$20 | Yes |
| Band-aids / blister pads | Walking-heavy port days | $10–$18 | Yes |
| Electrolyte packets (Liquid IV, Pedialyte) | Heat, dehydration, hangover | $18–$35 | Yes |
| Eye drops (lubricating) | AC-heavy ships dry eyes out fast | $14–$22 | Yes |
| Melatonin | Crossing time zones, irregular sleep | $10–$18 | Yes |
| Prescription antibiotic (ask your doctor) | Traveler's diarrhea backup plan | Requires $150+ doctor visit + Rx | Ask your doctor pre-trip |
Bottom line: a complete home pharmacy kit costs $60–$120 at Walmart or Target before you leave. Buying the same items onboard costs $250–$450+.

Key Factors That Drive Medication Costs on a Cruise
1. Ship pharmacy markup is brutal. Cruise ship pharmacies operate as a captive market. A pack of Dramamine that costs $8 at CVS runs $22–$30 onboard. Sunscreen that costs $10 at home? Expect $30–$45 on the ship. They know you need it and you can't go elsewhere.
2. Doctor visits are not free — and not cheap. The ship's medical center is a licensed medical facility, which means every visit is billed like one. A basic consultation runs $150–$300. If you need IV fluids for dehydration, blood work, or an EKG, costs escalate to $500–$2,000+. Travel insurance covers most of this, but the hassle of a sick day at sea is reason enough to pack well.
3. Caribbean and Mexican ports have pharmacies — but it's complicated. In ports like Cozumel, Nassau, or Roatán, local pharmacies are cheap and often sell prescription drugs OTC. But timing is the problem: you're in port for 6–8 hours, and getting sick between ports means ship prices or nothing. Don't count on port pharmacies as your backup plan.
4. Prescription continuity is a real risk. If you take blood pressure medication, thyroid medication, psychiatric medications, or insulin — running out at sea is a genuine medical emergency. Most cruise lines will try to help through their medical center, but it may mean flying medication to the next port at your expense or paying $200+ for an emergency supply. Bring double your expected supply and split it between your carry-on and checked luggage.
5. Motion sickness hits harder than most people expect. Even people who've never been seasick get surprised on open-ocean crossings or in rough Caribbean waters. The first 24–48 hours at sea are the highest-risk window. Start motion sickness medication the night before or morning of departure — don't wait until you're already green.

Practical Tips to Save Money and Stay Healthy
Pack before you leave — obviously, but specifically:
- Use a pill organizer for daily medications so you can pack extra doses without doubling your bottle count
- Keep all prescription medications in carry-on luggage only — never checked bags that could get lost
- Bring a written list of all prescriptions including dosage and generic names (useful internationally)
- Ask your doctor about a standby antibiotic prescription (ciprofloxacin or azithromycin) for traveler's diarrhea — this one script can save a miserable day and a $300 ship doctor visit
Buy smart before you board:
- Costco and Walmart have the best prices on sunscreen, OTC medications, and electrolytes in bulk
- Pick up a small first-aid kit ($12–$18) as a base, then supplement it
- Consider a travel-sized pill case with ibuprofen, antacid, Imodium, Benadryl, and motion sickness tabs — this one item covers 80% of cruise health issues
Get travel insurance that covers medical evacuation: This isn't a medication tip but it's part of the same conversation. Medical evacuation from a cruise ship can cost $50,000–$100,000+. A solid travel insurance policy with evacuation coverage runs $100–$300 for a week-long cruise. It's the single best health investment you can make.
For motion sickness specifically:
- Bonine (meclizine) causes less drowsiness than Dramamine and is the go-to for most cruisers
- Scopolamine patches (prescription) are the gold standard for severe sufferers — get the prescription before you leave
- Sea-Bands (acupressure wristbands) work for some people and cost $10 — worth tossing in the bag as a non-drug backup
- Ginger candies and ginger chews are a real secondary option for mild nausea
Destination-specific additions:
| Destination | Extra Medications to Consider |
|---|---|
| Caribbean / Mexico | DEET insect repellent, malaria prophylaxis if visiting certain ports (ask your doctor), extra sunscreen |
| Alaska | Fewer bug concerns, but lip balm, blister pads for hiking, and cold/flu meds for chilly excursions |
| Mediterranean | Standard kit applies; pharmacies in port are excellent and affordable if you run short |
| Transatlantic | Extended sea days = highest motion sickness risk; double your supply |
| Hawaii | Sun protection is critical; water-resistant SPF 50+ and reef-safe sunscreen required at some parks |
What the Ship's Pharmacy Actually Stocks (and What It Doesn't)
Most large cruise ships carry a reasonable selection of OTC medications — basic pain relievers, antacids, motion sickness tabs, cold medicine, and first-aid supplies. They do not typically carry:
- Your specific brand-name prescription medications
- Controlled substances (opioids, benzodiazepines, stimulants for ADHD)
- Specialty medications (biologics, immunosuppressants, some inhalers)
- Insulin pens or specific diabetes supplies
The ship's doctor can write prescriptions in some cases, but fulfilling them depends entirely on what's in the ship's formulary. For any specialty medication, assume the ship cannot help you and pack accordingly.
