My daughter and I both have Long QT syndrome and have been told to say away from anti-histamines and decongestants, but is there anything that we can take to alleviate cold symptoms? I've tried Afrin and Vicks vapor rub, I was not sure about the Afrin, but my daughter was so miserable we gave it a try. It didn't do much good anyway so we stopper after one try. The Vicks did little to help. We also did Saline nasal spray, which she did ok with. Any other ideas?
