for years I was on the generic triamterene/hydrochloro thiazide from mylan 25-37. I did fine on the med. Then all of a sudden caremark sends me the generic from sandoz. about a 3months i have been taking the sandoz I get light headed spells and ache in my joints. It is the only change in meds for a long time. Do you think the new bp cap may be causing the lightheadness?
