How to Get Dicyclomine for Travel: An ER Physician's Guide to Stopping Gut Cramps on the Road
Dicyclomine calms the cramping and spasms of traveler's diarrhea fast. Here's how to get it before your trip, dosing, and how it differs from antibiotics.
How to Get Dicyclomine for Travel: An ER Physician's Guide to Stopping Gut Cramps on the Road
Dicyclomine (brand name Bentyl) is an antispasmodic that relaxes intestinal smooth muscle, and it is prescription-only in the United States. The fastest way to get it before a trip is a telehealth travel health service like Wandr: you complete a short intake, a clinician reviews your history and destination, and the prescription is called in to your local pharmacy for pickup, often the same day. Dicyclomine does not treat the underlying infection behind traveler's diarrhea, which affects an estimated 30 to 70 percent of travelers over a two-week trip according to the CDC. What it treats is the cramping and spasm that make traveler's diarrhea miserable. In my ER shifts, I see patients who packed an antibiotic for infection but nothing for the pain that hits first, and that gap is exactly what dicyclomine fills.
What Dicyclomine Actually Does
Dicyclomine is an anticholinergic antispasmodic. It works by blocking acetylcholine receptors on intestinal smooth muscle, which reduces the involuntary contractions, or spasms, that cause cramping pain during a GI illness.
That mechanism matters because traveler's diarrhea is not one symptom. It is a cluster: loose stools, urgency, and often sharp, cramping abdominal pain that can double you over on a bus, in a market stall, or mid-hike. Antibiotics like azithromycin target the bacteria causing the infection. Antimotility agents like loperamide slow down stool frequency. Dicyclomine targets neither of those. It targets the muscle spasm itself, and for a lot of travelers, the spasm is the symptom they actually want gone first.
I think of it as three different jobs for three different tools: kill the bug, slow the flow, calm the cramp. Most travel medicine kits only cover the first two.
Why Cramping Deserves Its Own Medication
The CDC Yellow Book describes traveler's diarrhea as ranging "from mild cramps and urgent loose stools to severe abdominal pain, bloody diarrhea, fever, and vomiting," which puts cramping squarely in the clinical picture from the mild end of the spectrum onward. Bacteria account for an estimated 75 to 90 percent of cases, and the cramping response is part of how the gut reacts to that irritation, regardless of which specific organism is involved.
Cramping is also what tends to interfere with an actual trip. A traveler can often tolerate one or two loose stools during a long travel day. Doubling over with intestinal spasms during a temple tour, a game drive, or a flight is a different problem. That is the scenario where a dedicated antispasmodic earns its spot in a travel kit, alongside, not instead of, whatever the CDC-recommended antibiotic or antimotility regimen calls for.
We also see this scenario play out in people who have an underlying tendency toward cramping, like a history of irritable bowel syndrome, who are understandably nervous about how their gut will react to unfamiliar food, water, and stress on a trip. Post-infectious irritable bowel syndrome is a recognized complication of an acute bout of travelers' diarrhea, so a traveler who already deals with gut sensitivity has good reason to want cramping specifically covered, not just diarrhea frequency.
How to Get Dicyclomine for Travel: Step by Step
Dicyclomine requires a prescription in the United States. There is no over-the-counter version. You have three realistic paths, and the right one usually comes down to how much time you have before departure.
- Online travel health service (fastest). Complete a digital intake covering your destination, trip dates, and medical history. A licensed clinician reviews it and, if appropriate, calls the prescription in to your local pharmacy for pickup. No in-person visit required. This is what Wandr does, often within hours.
- Your primary care doctor. If you already have an upcoming appointment and your trip is weeks out, ask specifically about a travel-cramping antispasmodic. The limitation is scheduling: primary care visits booked for travel prep alone can take weeks to land.
- A traditional travel clinic. Comprehensive, but usually the slowest and most expensive route. A single consultation can run well over $100 before medication costs, and most require advance booking.
Whichever route you take, build in a buffer. You want dicyclomine filled and in your carry-on before departure, not something you are chasing down at a pharmacy the night before a flight.

"Cramping is the symptom that actually stops people mid-trip. I've had ER patients who packed an antibiotic for infection but nothing for the pain that hits first. An antispasmodic is a small addition to a travel kit that solves a specific, common problem." (Alec Freling, MD, Wandr Health)
Dicyclomine Dosing for Travel
For adults, the typical dicyclomine dose for intestinal spasm and cramping starts around 20 mg taken by mouth up to four times daily, and can be titrated by a clinician to a higher dose if needed and tolerated. Some prescribers use a lower starting dose in the first days of a new prescription to gauge tolerance before increasing.
A few points I cover with every travel patient:
- Take it for the cramping, not on a fixed schedule. Dicyclomine for travel is generally used as needed when spasm and cramping symptoms are active, not as a preventive taken daily regardless of symptoms.
- It does not replace an antibiotic or antimotility agent. If your itinerary calls for a standby antibiotic like azithromycin or ciprofloxacin, or an antimotility agent, dicyclomine is an addition, not a substitute.
- Anticholinergic side effects are common and usually mild. Dry mouth, blurred vision, dizziness, and drowsiness can occur. Avoid driving or operating a vehicle until you know how it affects you.
- It is not appropriate for everyone. Dicyclomine should be avoided in people with glaucoma, certain heart rhythm conditions, urinary retention, or severe ulcerative colitis, and dosing in pregnancy, breastfeeding, and pediatric travelers should always be set by a clinician.
Any of these details should be confirmed with your own prescriber based on your health history and itinerary, not treated as a fixed rule.
Dicyclomine vs Loperamide vs Antibiotics: What Each One Actually Fixes
These three categories solve different problems, and the CDC's own severity framework treats antibiotics and antimotility agents as complementary, not interchangeable, tools. An antispasmodic like dicyclomine fits into that same complementary structure. It is worth discussing your specific itinerary and risk factors with a clinician so your kit covers the symptoms most likely to actually disrupt your trip.
Who Should Consider Packing Dicyclomine
Dicyclomine is not something every traveler needs to carry. Our providers tend to recommend it for:
- Travelers with a history of IBS or gut sensitivity who want cramping specifically covered, given the known link between acute travelers' diarrhea and post-infectious IBS.
- Long-haul and remote itineraries where reaching a pharmacy quickly is not realistic, such as multi-day treks, safaris, or rural regions.
- Travelers heading to high-risk destinations for traveler's diarrhea, including much of Latin America, Africa, and South and Southeast Asia, where attack rates run highest.
- Anyone who has previously had a trip disrupted by cramping, independent of how the diarrhea itself resolved.
If none of that describes your trip, a standard kit with an antibiotic and loperamide may be all you need. This is exactly the kind of judgment call our clinicians make during a Wandr intake, matched to your actual itinerary rather than a generic checklist.

Packing It With the Rest of Your Travel Health Kit
Dicyclomine works best as one piece of a broader plan, not a standalone fix. A well-stocked travel diarrhea kit typically includes a standby antibiotic (azithromycin is the CDC's preferred first-line choice for South and Southeast Asia), an antimotility agent like loperamide for long travel days, oral rehydration salts, and, for travelers prone to cramping, dicyclomine.
Our clinicians review your full itinerary, not just one symptom, so if you are also asking about altitude, motion sickness, or malaria prevention for the same trip, that gets covered in the same visit rather than a separate one.
Start your visit on Wandr and get a clinician-reviewed medication plan called in to your local pharmacy before you leave.
Frequently Asked Questions
Is dicyclomine the same as Bentyl? Yes. Bentyl is the common brand name for dicyclomine. They are the same active medication, and most pharmacies will fill either the generic or the brand depending on your insurance and the prescription written.
Do I need a prescription to get dicyclomine for travel? Yes. Dicyclomine is prescription-only in the United States and is not available over the counter. A licensed clinician needs to review your health history first, which a telehealth travel service can typically do the same day.
What is the dicyclomine dosage for traveler's diarrhea cramping? The typical adult dose is around 20 mg taken as needed, up to four times daily, for active cramping, though your prescriber may adjust this based on tolerance and response. Follow your clinician's specific instructions rather than a fixed general dose.
Does dicyclomine stop diarrhea? Not directly. Dicyclomine targets the muscle spasm and cramping pain associated with traveler's diarrhea, not the stool frequency or the underlying infection. Loperamide addresses stool frequency, and an antibiotic addresses the infection itself.
Can I take dicyclomine with an antibiotic or loperamide? Generally yes, since the three target different problems, but this should be confirmed with your prescriber based on your specific health history and the medications involved.
Who should avoid dicyclomine? People with glaucoma, certain heart rhythm disorders, urinary retention, or severe ulcerative colitis are generally advised to avoid dicyclomine. Pregnant or breastfeeding travelers and children should only use it under a clinician's direction.
How far in advance should I get dicyclomine before my trip? Aim to have it filled and packed at least a few days before departure. Through an online travel health service, the prescription can often be called in to your pharmacy the same day, but you want it settled before travel day, not squeezed in at the last minute.
Is dicyclomine safe for long-term daily use while traveling? Dicyclomine for travel is typically used as needed for active symptoms rather than as a daily preventive. Extended daily use should only happen under a clinician's supervision, since anticholinergic side effects can accumulate.
