Yes You Can-I Was Delivered My Prescriptions For Venlafaxine ER

Yes you can-I was delivered my prescriptions for Venlafaxine ER and Letrozole today. The Letrozole pills are white usually. Today, in the same bottle are two different pill colors of light tan and white. In the Venlafaxine ER bottle pills are orange. Usually they are brown. The bottle says generic was dispensed. I was not asked if this was ok. I have previously spoken to the pharmacist/manager about receiving 2 diff. pills in one bottle. He said he would take care of it. My neurologist says I can't take different pills. I called one nurse who refused to help. Waiting for response from another. What can I do? YYYY@YYYY
