At night the bars come to life. The crowd after dark is primarily teenagers and young adults. The police are active in the evenings, but trouble sometimes occurs. A block or two west of the Juarez strip are the more seedy bars and clubs. Most are made by Mexican subsidiaries of the large multinational pharmaceuticals so quality control is good.
Access is good - there seems to be a farmacia on every corner.
Two that cater to tourists are the Rio Grande Pharmacy on Av. 16th de Septiembre near to the City Market and Farmacias Nacional on Av. Juarez just across the Santa Fe Bridge. U.S. Customs regulations state that you can only carry the amount of a prescription for personal use back into the U.S. and that you should have a copy of the prescription.
