Anyone know anything about pharmacology?

If I have a .5 mg dose for an anxiety medication (clonazepam) that I use for flying, can I take 2 if I feel like one dose isn’t enough? Common dosage breakdowns are .5, 1, &2 mg so I know the active ingredient itself is safe in larger amounts, just not sure about pill binders and such.

Yes i could call the pharmacy but I am pretty sure they would advise me against it since it’s just not exactly what my doctor prescribed. Flight is tomorrow so I don’t have time to get another prescription.
