For the usual trip, no. The CDC lists malaria only in the forested areas along the Myanmar, Cambodia, and Malaysia borders. Bangkok, Phuket, Chiang Mai, Koh Samui, the Krabi islands, and Pattaya have no malaria, so no pills are needed for a standard Thailand trip. Only a trek into the remote border forests raises the question. The travel health issue that actually matters here is traveler's diarrhea. CDC guidance checked June 19, 2026.
| Destination | Malaria pills? | Why |
|---|---|---|
| Bangkok, Chiang Mai, Chiang Rai, Phuket, Krabi, Koh Samui, Koh Phangan, Phi Phi, Pattaya | No | CDC lists no or only rare malaria here. Traveler's diarrhea is the more common concern. |
| Rural, forested areas along the Myanmar, Cambodia, and Malaysia borders | Yes | CDC lists malaria in these border forests. Doxycycline or Malarone are appropriate for a trek there. |
So the classic Thailand trip, cities, beaches, and islands, needs no malaria pills. Only a remote jungle trek along a border raises the question.
For Thailand's border forests the CDC lists atovaquone-proguanil (Malarone), doxycycline, and tafenoquine. It does not list chloroquine or mefloquine here because resistance to both is common in this region, which is an important detail. Two of the recommended options, doxycycline and Malarone, we prescribe for a flat $45, sent to your own pharmacy. See doxycycline vs Malarone.
I am Bidwell Cranage, a nurse practitioner and Member of the International Society of Travel Medicine, and I traveled Thailand and Cambodia myself. I did not need malaria pills for the usual route, cities, beaches, and islands, and I would not pay a service to bundle a pill I did not need. What I got was the typhoid vaccine beforehand, and what I would carry is a standby antibiotic for the stomach. Those are the things that matter for a normal Thailand trip.
For most Thailand trips, the thing worth preparing for is traveler's diarrhea, not malaria. Many travelers carry a standby azithromycin course so a bad case does not cost them island or temple days. We can include it with your visit for the flat $45.
We do not give vaccines. We refer you to a travel clinic for those and can handle a standby antibiotic, a scopolamine patch for ferries, or border-area malaria pills online. See online travel medicine vs a travel clinic.
For one flat $45 visit, sent to your own pharmacy with no markup, we can cover a standby antibiotic for traveler's diarrhea (the most common Thailand need), a scopolamine patch for ferries to the islands, and malaria pills (doxycycline or Malarone) only if you are trekking a border forest. We refer you to a travel clinic for hepatitis A and typhoid shots, and for tafenoquine or pregnancy.
For most trips, no. The CDC lists malaria only in the forested areas along the Myanmar, Cambodia, and Malaysia borders. Bangkok, Phuket, Chiang Mai, Koh Samui, the Krabi islands, and Pattaya have no malaria, so no pills are needed for a standard Thailand trip. You only need them for a trek into the remote border forests.
No. The CDC lists Bangkok, Chiang Mai, Phuket, the islands, and Pattaya as having no or only rare malaria cases, so it does not recommend malaria pills for them. The more common travel health issue on these trips is traveler's diarrhea, which a standby antibiotic can cover.
Only in the rural, forested areas along the borders with Myanmar (Burma), Cambodia, and Malaysia. For those border areas the CDC lists atovaquone-proguanil (Malarone), doxycycline, and tafenoquine, because chloroquine and mefloquine resistance is common there. We can prescribe doxycycline or Malarone for that kind of trip.
For most travelers the priorities are a standby antibiotic for traveler's diarrhea and the recommended vaccines, hepatitis A and typhoid, which are shots given at a travel clinic. A scopolamine patch helps if you are taking a ferry to the islands. We can handle the standby antibiotic and the patch online for a flat $45, and refer you to a clinic for the shots.
