Can I bring Sudafed into Thailand? (2026)

Allowed only if you arrange approval first.

Sudafed contains Pseudoephedrine (also sold as Sudafed, Claritin-D). Carry it in original packaging with your prescription or a doctor's letter.

• Pseudoephedrine is controlled in Thailand - you need an import permit or advance approval before you travel.
• Apply ahead of time and carry the approval together with your prescription.
