Short answer. Costa Rica publishes no official guidance on potassium iodide (KI). No stockpile, household distribution, distribution zones or sale status was found from the national emergency commission (CNE) or the Ministry of Health, as checked on 2026-10-20. If you have a question about iodine tablets in Costa Rica, ask a doctor or pharmacist, and take them only on an instruction from the authorities.
Is potassium iodide distributed in Costa Rica?
No official distribution was found. Costa Rica's preparedness material from the CNE, including the family plan guide and its emergency-case list, does not mention iodine tablets. See emergency supplies for what the CNE does ask households to keep.

Should I take iodine on my own?
Not without an instruction from the authorities. Our guide explains what it does and its limits, with its own sources: /guides/potassium-iodide. Since Costa Rica publishes no rules, ask a doctor or pharmacist before buying any.
What else protects against fallout?
Sheltering indoors and limiting exposure matter more than tablets. These guides explain the principles, with their own sources:
- /guides/fallout-7-10-rule: how fallout radiation decreases over time.
- /guides/protection-factor: how much protection different buildings give.
- /guides/radiation-decontamination: what to do after exposure.
- /guides/nuclear-explosion: the first actions after a detonation.
In any emergency, follow the CNE's instructions; see alerts for how they are issued, and call 9-1-1 if you need help (emergency contacts).
