Pharmacies in San Cristóbal de las Casas: 24-Hour Options & Prescriptions

Use a current 24-hour Centro branch for a routine late-night purchase; do not use a pharmacy as a substitute for emergency care. Antibiotics and tramadol have prescription restrictions in Mexico, so confirm the medicine and current branch status before going. For urgent care, use 911 and the Medical Care guide.

Quick answer

24-hour central examples: Farmacia Guadalajara Crescencio Rosas and Farmacias del Ahorro Catedral
Antibiotics: prescription required in Mexico
Tramadol: controlled medicine since July 14, 2026; COFEPRIS says dispensing requires a simple medical prescription
Before a special trip: recheck the live Place page because branch hours can change

Farmacia Guadalajara Crescencio Rosas

Farmacia Guadalajara Crescencio Rosas is in the central area at Crescencio Rosas 17. A current local business listing shows 24-hour operation.

Treat that schedule as a current branch fact, not a permanent guarantee. If you are going late at night, recheck the live listing before walking across town.

Farmacias del Ahorro Catedral

Farmacias del Ahorro Catedral is at General M. Utrilla 2 near the central cathedral area. The chain’s current online listings confirm the San Cristóbal Catedral branch, and a current business listing shows it as 24 hours.

Prescription medicines

Do not assume that a medicine sold in Mexico is available without a prescription.

Mexico’s official rules require a medical prescription for the sale and dispensing of antibiotics. A pharmacy must follow the applicable prescription rules rather than treating an antibiotic like an ordinary over-the-counter purchase.

COFEPRIS also announced a new 2026 rule for tramadol: from July 14, 2026, it is classified as a controlled medicine under Fraction III, and dispensing requires a simple medical prescription issued by a physician with a professional license.

Other controlled medicines can follow different rules. If you need a specific prescription drug, ask the pharmacy what documentation is required rather than relying on an old travel forum.
