We will have a party of 18 leaving for Mexico the 22nd. Many in our party take prescription meds, some of which include Adderall, Xanax, anti-depressants, the diet pill Phentermine, and a nightly shot a lady must give herself for osteoporosis. What are the rules regarding bringing prescription meds into Mexico? I have read some horror stories of people being thrown in Mexican jail for trying to bring different things in. Thanks!
