Cold And Flu Warning: The Dangers Of Too Much Acetaminophen
- By Susan Farrell, MD, Contributing Editor
Cold and flu season is here.
Peruse the aisles of a local pharmacy or grocery store and you will find more than 30 over-the-counter medications available to treat the symptoms of fever, headache, sore throat, and achy muscles. Many of these multi-symptom products contain acetaminophen, the active ingredient in Tylenol. This means cold and flu sufferers who are using multiple combination cough and cold remedies may inadvertently be taking more acetaminophen than they intend and putting themselves at risk for a serious complication: acetaminophen-induced liver toxicity.
Acetaminophen is the most commonly available pain-relieving and fever-reducing medication. It is an ingredient in more than 600 over-the-counter and prescription medications, and it has a remarkable safety profile: the dose at which potential toxicity occurs is dramatically higher than the amount that most adults need to effectively treat their symptoms . Moreover, acetaminophen does not cause the unwanted effects that are associated with non-steroidal anti-inflammatory drugs or prescription opioids. As a result, acetaminophen is known as a very safe and effective over-the-counter medication for the treatment of pain and fever, and is taken by millions of people.

To treat a cold or the flu, its a good idea to drink lots of fluids. Be sure to avoid drinks like coffee, tea, and colas, as they contain caffeine that can dehydrate you.
Your body also needs energy to fight off infection. If youve lost your appetite, try eating simple foods like white rice or soup.
Multi-symptom cold & flu remedies like Theraflu® products contain a combination of active ingredients for symptom relief. Symptom relief will vary by product.
Never give aspirin to children or teenagers who have flu-like symptoms, particularly a fever.
