The TSA permits "All prescription and over-the-counter medications (liquids, gels, and aerosols) including KY jelly, eye drops, and saline solution for medical purposes;... However, if the liquid medications are in volumes larger than 3 ozs each, they may not be placed in the quart-size bag and must be declared to the Transportation Security Officer."

Rogaine is an OTC medication. End of story. Of course the TSA policy I quoted means that all toothpastes with fluoride are allowed, regardless of the container volume, but that directly contradicts their statement that "Larger containers that are half-full or toothpaste tubes rolled up are not allowed." They allow 4oz+ fluoridated toothpaste, but do not allow it.

Of course this is the TSA; the people that can't figure out that tsa.gov should probably redirect to www.tsa.gov when making an http request.
