Pharmacies on Koh Samui: availability and what to know

Pharmacies (raan kai yaa) are one of the easiest parts of healthcare on Koh Samui. You will find them throughout Chaweng, Lamai, Bophut, Maenam and Nathon, including branches of chains such as Boots and Watsons in shopping areas, and independent pharmacies on every main road. Many medicines that require a prescription in Western countries are sold over the counter in Thailand, including common antibiotics, anti-inflammatories and stronger painkillers, and pharmacists in tourist areas generally speak enough English to help with routine problems; for minor ailments like traveller's diarrhoea, allergies, motion sickness, sunburn or small wounds, a pharmacy visit is often all you need, and basics like oral rehydration salts cost a few baht. Practical cautions: buy from proper pharmacies, not market stalls; check expiry dates; and be aware that medicine quality controls differ from home, so well-known chains and busy pharmacies are the sensible choice. If you take regular prescription medication, bring enough for your whole trip plus a buffer, in original packaging with a copy of your prescription; your exact brand may not exist in Thailand, so know the generic (international) name of each medicine, which lets a pharmacist find the local equivalent. Some medicines legal at home are controlled in Thailand, particularly strong painkillers, ADHD medication and some anxiety medicines; check Thailand's rules before travelling with them, and never buy controlled medicines without a proper prescription. For anything beyond routine issues, see a doctor rather than self-medicating.

Pharmacies are everywhere on Koh Samui, in every tourist town and shopping area, and many medicines that need prescriptions elsewhere, including common antibiotics and painkillers, are sold over the counter.
