I have taken Triamterene W/Hctz, 37.5/ 25mg gotten as a round, light green tab. (Medco) Now we were changed to Express Scripts and the same presc. came as an oval green color. Started in April and I've had muscle aches & pains that are terrible. Are there diffences in these types of meds., shape and color? Who makes them? Am quitting this oval one and am getting better. Explain the differences please! I also take Prinovil 10mg, Dr. ordered to take it as half tab. Can there also be a reaction taking these two meds. together? Explain, please!
