I have been infused with Zemaira since July of 2012. I have had a 24/7 headache since May of 2014. I am trying to rule out all possible interactions that may be causing my headache. Do any of the following durgs/supplements interaction with Zemaira be causing my headache? I take spiriva, advair, gabapentin, lunesta, Vitamin D-3, an herbal for prostate health, Vitamin B-1, Magnesium and Rose Primrose.
