Miss L,
You're fine.
Taking straight Micardis (non HCT) with Maxide is okay.
From everything I've read, Micardis (non-HCT) should not significantly affect potassium levels, if at all.
I've found a LOT of mistakes written about Micardis on the internet, including several references that make the assumption that it contains a diuretic automatically. It does not. You are right, there's Micardis HCT and regular Micardis.
Maxide is a combo of two diuretic agents, hydrochlorothiazide and triamterene. The triamterene maintains or increases sodium excretion and reduces the excess loss of potassium, (also hydrogen, and chloride ions) sometimes caused by hydrochlorothiazide. Hence the name "potassium sparing".
As long as your routine bloodwork shows no potassium depletion, you should have no worries. If you experience any weakness, fatigue, dizziness, or headache, these can be signs of problems with the diuretic in general.
Just continue monitoring your BP, keep regular appts with your doc as indicated, and relax!
