the data sheets can also be googled.
When your pharmacist orders this stuff there is a fact sheet taped to the side of the jar with drug information on it. It tells you everything including how many people died during the testing of the drug. Ask for one.

I just recently had a very similar experience! After starting taking benicar I started experiencing almost debilitating headaches as often as three times a day. My doctor sent me to a neurologist who diagnosed me with cluster headaches and prescribed Imitrex which treated the pain but didn't keep it from continuing. I ran out of benicar, but before I got a chance to get my prescription refilled I noticed that my headaches had stopped! It's good to see I'm not the only one!
I've been on 40/25 mg of Benicar HCT for 3 years and have never experienced headaches. This drug has done wonders for me lowering my BP to 105/70 from 180/90. It takes time to get used to BP meds, if Benicar does not work for you or you have side affects your doctor will have other options for you. I woud try to stick it out on the Benicar, it's a very good medication.
Good Luck!
