Controlled Medications in Colombia 2026: What Foreigners Need to Know Before Packing

The family doctor of Ingrid — a Danish citizen living in Bogotá — had prescribed her methylphenidate (Ritalin) for attention deficit disorder for eight years. When Ingrid arrived in Colombia with a three-month supply in her luggage, she did not foresee that the medication was classified as a special-control substance in Colombia and that carrying 90 tablets without the specific Colombian documentation was a violation that could cost her the confiscation of the medication and an administrative proceeding before INVIMA. Customs let her through. But when she tried to renew the prescription in Colombia, she discovered that Colombian psychiatrists cannot simply validate a foreign prescription for this type of substance — they must issue a new one, with all the Colombian controls.

Which Medications Are Controlled in Colombia

Colombia classifies as "special-control medications" the psychotropic and narcotic substances listed in the schedules of the 1971 Vienna Convention and the 1988 United Nations Convention, as well as national medications on INVIMA's lists. Medications commonly used by foreigners that fall into this category include: methylphenidate (Ritalin, Concerta), amphetamines (Adderall), benzodiazepines (Diazepam, Alprazolam), high-dose tramadol, and prescription opioids.

Entering Colombia with Controlled Medications

Colombian rules allow you to enter the country with special-control medications for personal use as long as: the traveler carries the original prescription valid in their country of origin (with an official translation if it is not in Spanish), the supply does not exceed 30 days of treatment at the prescribed dosage, and the medication is in its original packaging with a pharmacy label. It is also advisable to carry a letter from the treating doctor in English or Spanish explaining the diagnosis and the need for the treatment.

Renewing the Prescription in Colombia

Colombian doctors can prescribe special-control medications for foreign patients, but the process is not the simple validation of a foreign prescription. It requires an in-person consultation with a Colombian specialist (a psychiatrist for psychiatric medications, the treating doctor for others), an assessment of the patient according to Colombian standards, and the issuance of a Colombian prescription in INVIMA's special-control format. Some private clinics in Bogotá and Medellín have experience with foreign patients and can guide the process.

What Can Be Confiscated at Customs

Colombian customs has the authority to hold medications without the correct documentation. The most frequent cases involve: supplies exceeding 30 days without supporting documentation, medications without the original prescription, and substances that have no INVIMA registration in Colombia (even if they are legal in the country of origin). The hold is administrative — it does not involve criminal proceedings — but recovering the held medication can take weeks and require handling through a lawyer or the consulate of the country of origin.
