Why cannot reputable surgeons in Mexico or Tijuana prescribe medication after surgery?

I want to share with you that, it is correct, believe it not, the access to all type of narcotics, you name them: painkillers, anti-anxiety, sleeping pills, and definitely IV ones, are totally restricted to our access as doctors or specialists. Only anesthesiologist or psychiatrist are allowed to have the special and very well observed prescriptions. For us is a crime to prescribe without THAT special permission. Plus you can not deny or ignore that the US has a very high problem with drug addiction mainly because doctors are allowed to prescribe narcotics as candy. I just want to tell you,  that narcotics are very serious and anyone may DIE  as a result of an overdose specially after a surgical procedure when your body is so weak and vulnerable.   So be careful. In my practice I use pain pumps with great control over postoperative pain. Dr. Cardenas 

Patients that go out of the country for surgery, should be aware that many of the laws governing medicine are not the same. Additionally, the warranties on medical devices are different. For example, if you have a breast augmentation in Mexico, and the implant deflates when you come back to the United States. The warranty will not be recognized.The cost savings on the initial price of the surgery, may not be realized in the long run.Yours, Jon M. Grazer, MD, MPH, FACS

There are different regulations and policies for many countries.  I
would search for the board certified plastic surgeon who you feel is
most likely to give you the best results and who performs hundreds of
these procedures each year. I would look at patient reviews as well as
before and after photos on that surgeon's website.Kenneth Hughes, MDLos Angeles, CA

It looks as though you are writing from California, so the issue is probably that their license is not valid in California. I'm sure they could prescribe you drugs to be filled in Mexico, but your question highlights one of the many reasons that medical tourism is not a good idea. If you want to have a safe procedure and be able to fill your prescriptions locally then get a consultation with a board certified plastic surgeon near you.
