Xanax does not interact significantly
with cocaine. If a person came to the ER
with anxiety from cocaine, a Xanax-like medication would likely be given to the person.
But I can't really say it is 'safe' to take Xanax after cocaine. The Xanax is not likely to do anything bad, assuming you take it in a reasonable, therapeutic dose. But cocaine is NEVER a 'safe' medication.
