Prescriptions for High blood pressure. My physician has placed me back on Clonidine HCL for hypertesnsion.Taking 1 pill three times per day! I received one prescription for 30 days supply at .10 mg! However three days later my on line pharmacy that I use with my supplemental prescription drug policy sent me Olmesartan Medoxomil (40 miligram tablets/1 per day).From my reading on line they are similar drugs to treat high blood pressure and hypertension! My question is will I be taking to much of this drug of I take the 40 mg and the three tablets of .10 mg??
