Playing Harmful Over-the-Counter Combinations?

Aspirin & Ibuprofen: Taking both of these meds increases your risk for bleeding, including gastrointestinal bleeding and even the possibility of developing stomach ulcers.

St. John’s Wart & Cough Medicine: The combination of the herbal supplement – which some use for depression – and cough syrup could be deadly, Dr. Elliot warns. It can cause serotonin syndrome, an excessive of serotonin in the body. Too much serotonin can lead to sweating, confusion, tremors, diarrhea, discomfort, trouble controlling your moments, and in rare cases even death.

Caffeine & Decongestants: Mixing your morning pick-me-up or even your caffeinated hot tea with a decongestant can increase your heart rate and raise your blood pressure. Dr. Elliot notes that caffeine is often an ingredient in many of our headache and pain meds, so please read carefully if taking one.
