Malaria · Thailand
For most trips to Thailand, no, you do not need malaria pills. Bangkok, Phuket, Chiang Mai, Krabi, Pattaya, and the islands have no malaria risk, so the CDC does not recommend malaria pills for them. You only need them for specific rural, forested areas along the Myanmar, Cambodia, and Laos borders. Our founder traveled Thailand and Cambodia and did not need malaria pills for the usual tourist route.
| Destination | Malaria risk | Pills recommended? |
|---|---|---|
| Bangkok | None | No |
| Phuket, Krabi, Koh Samui, the islands | None | No |
| Chiang Mai, Chiang Rai (cities) | None | No |
| Pattaya | None | No |
| Rural forests near the Myanmar / Cambodia / Laos borders | Present | Yes, for those areas |
This is why "do I need malaria pills for Thailand" almost always comes down to one question: are you going into the remote border forests, or staying on the normal tourist circuit? The standard itinerary, temples, beaches, cities, and islands, carries no malaria risk.
For the rural border zones that do have risk, doxycycline or Malarone (atovaquone-proguanil) are the right choices. Mefloquine is specifically avoided along the Thai borders because the parasite there has developed resistance to it. (See doxycycline vs. Malarone to choose.) These are also areas where, if you develop a fever, you should seek care promptly.
Even with no malaria pills, a few things are worth sorting before a Thailand trip:
I got my typhoid vaccine before Thailand and Cambodia, and I have seen how often travelers over-prepare for malaria here when the real risks on the usual route are the stomach bug and dengue. I would rather tell you honestly that you do not need malaria pills than sell you something you will not use.

For most trips, no. Thailand's major tourist destinations, including Bangkok, Phuket, Chiang Mai, Krabi, and the islands, have no malaria risk, so the CDC does not recommend malaria pills for them. You only need malaria pills if you are traveling to specific rural and forested areas along the Myanmar, Cambodia, or Laos borders.
No. There is no malaria risk in Bangkok, Phuket, Chiang Mai, Pattaya, Krabi, Koh Samui, or the other main tourist areas. Malaria in Thailand is limited to certain rural border regions.
If you are visiting the rural border zones that do have risk, doxycycline or atovaquone-proguanil (Malarone) are preferred. Mefloquine is avoided in these areas because of drug resistance along the Thai borders.
Even without malaria pills, travelers to Thailand often want a standby antibiotic for traveler's diarrhea and insect repellent. Discuss vaccines such as hepatitis A and typhoid with a clinician or travel clinic before you go.
