BArb Mallut wrote It's been so long since I've had a cold that I have no memories of ever taking Sudafed, but it's none-the-less one of those "household words," like aspirin, Tylenol, Alka Seltzer and other popular over-the-counter medications, and I suspect I'd had it 'round the house in the past, if not for myself, then when my kids were growing up. Because it was such a familiar drug, I never even so much as glanced at the "Warning" on the Sudafed box when I took the drug. Later on, I picked up the box to see how often the drug can be taken and THEN I casually read the "Warning" on it. It said: "Do not use this product is you are taking a prescription monoamine oxidase inhibitor (MAO) (certain drugs for depression, psychiatric or emotional conditions, or Parkinson's disease), or for 2 weeks after stopping the MAO drug." Barb As an RN (non practicing but retain license in CA) I suggest that when taking OTC meds that you read the labels and precautions three times before purchasing. Helen
