All of my meds are PRN and I do have quite a few... Some I can go for months to a year without taking. Others I can go a few weeks without taking. And the rest I take a bit more regularly, but definitely not on a schedule. Fortunately they're prescribed as PRN....except for one which is not a typical PRN medication. Put a note in your wallet stating your current medications and doses. Its not uncommon for psychiatric medication doses to go up and down. My pdoc will prescribe for 6 months out, but I can get a med adjustment over the phone.....and end up with a lot of extra medication. I honestly don't think a hospital is going to look at what is prescribed to you at the pharmacy and then force it down your throat. That is, a pharmacy doesn't keep records about why you may have stopped the medication recently due to a severe reaction, etc. I can see many a hospital being sued up the wazoo for giving a patient medication based solely on what is prescribed at the pharmacy and getting no other input!
