The FAA's Do Not Issue table also names guanabenz, under centrally acting hypertensives, and the FAA's table says the examiner should defer the exam; it also says do not issue a medical certificate.
FAA rule for blood pressure medication: The FAA's hypertension worksheet (CACI) refers to the antihypertensive sheet for acceptable medications, and allows combinations of up to 3 of the classes it lists -- alpha blockers, beta-blockers, calcium channel blockers, diuretics, ACE inhibitors, ARBs, direct renin inhibitors and direct vasodilators -- and lists centrally acting antihypertensives, such as clonidine, as not acceptable. The Guide's hypertension table says the number of medications counts each component (for example, lisinopril/HCTZ is 2 medications), and that with 4 or more acceptable medications the examiner should defer.
