High Blood Pressure
"My doctor prescribed Triamterene/HCTZ 37.5 once a day about 6 months ago. In the meantime I experienced severe silent migraine type symptoms (light-sensitivity, motion sensitivity, brain fog, irritability, not able to read or think clearly) which I have never had before.  My doctor even did a brain MRI to try to find the cause but never thought of my medicines side effects.  I quit this medicine on my own and immediately noticed no more headache symptoms!  Have been off for 2 months now and no silent migraine instances have occurred."
