I noticed that you mentioned Verapamil as your normal prescription. I have been on the Calan SR form of this drug for almost 6 years. Two months ago my insurance provider changed my prescription to the generic form i.e. Varapamil. I don’t know if this just triggered a new wave of headaches or if the drugs are not the same. I did some research and found that all of the Varapamil based drugs are not necessarily interchangeable. After 2 months of serious headaches I started using the Calan SR again. The headaches slowed immediately, now they are almost completely gone. I hope this is of some help.
