I have used the same allergy and asthma meds for years/decades. I haven't changed any other medications. This used to be no problem — I could renew for 2 years easy. For some reason they started making me come in more often a few years back. Pretty annoying! I get that blood pressure meds or other dynamic issues require different kinds of care.
