Drug Interactions

Some drugs can also interact with foods and beverages, as well as with health conditions such as diabetes, kidney disease, and high blood pressure.
Here are a few drug interaction cautions for some common OTC ingredients:

  • Avoid alcohol if you are taking antihistamines, cough-cold products with the ingredient dextromethorphan, or drugs that treat sleeplessness.
  • Do not use drugs that treat sleeplessness [3].
  • Check with your doctor before taking products containing aspirin if you're taking a prescription blood thinner or if you have diabetes or gout.
  • [4] when you have stomach pain, nausea, or vomiting.
  • [5], do not use a nasal decongestant if you are taking a prescription drug for high blood pressure or depression, or if you have heart or thyroid disease, diabetes, or prostate problems.
