Report Best places to buy your medication in Ajijic/Chapala/Guadalajara Posted October 28, 2016 1 hour ago, bdlngton said: Yes, why beware of Farmacia Express? I have had 2 wrong prescriptions. One was serious, as it was for my stomach and it was a heart medication I already take a heart med. It was lowering my blood pressure and making me faint. A friend also got the wrong med and ended up in hospital. It is my understanding that a pharmacy is suppose to have a doctor on staff. The doctor was a very old man who just sat in a chair and died about a year ago.
