I started taking Midodrine 3 days ago(2.5 mg 2 times a day), to decrease episodes of syncopy- I have vasovagal syncopy. I also had a cardiac ablation to ameliorate Supra Ventricular Tachycardia episodes. However, I am now suffering from increased headaches ( I already have problems with migraine headaches), and a feeling of fatigue during the day. Should I continue on this medication ? Will the headaches go away over time if I continue taking this medication ? Shelley Slinkard
