How much is too much over-the-counter pain medication?
As you get older, it’s natural to develop aches and pains. But health experts say it’s important not to become reliant on pain killers like Tylenol or Ibuprofen to deal with your discomfort.
Overall, pain killers “shouldn’t be used for more than a few days in a row, and the specified maximum daily dose shouldn’t be exceeded,” according to a study from the National Library of Medicine.
The appropriate dosage depends on the type of pain relief medication you’re using, as well as on your existing conditions or current state.
Acetaminophen (Tylenol)
According to Medline Plus, Acetaminophen alleviates pain from “headaches, muscle aches, menstrual periods, colds and sore throats, toothaches, backaches, reactions to vaccinations and to reduce fever.” It’s also used for osteoarthritis pain relief.
Per Harvard Health, acetaminophen does not reduce inflammation like aspirin. But it also doesn’t irritate the stomach or intestinal lining like other common pain relievers.
How much you can safely take
These guidelines come from Harvard Health.
325 milligrams | 500 milligrams | 650 milligrams extended release | |
|---|---|---|---|
Number of pills | 1 or 2 | 1 or 2 | 1 or 2 |
Frequency | Every 4 to 6 hours | Every 4 to 6 hours | Every 8 hours |
Safest maximum dose for adults weighing 150 pounds | 8 pills | 6 pills | 4 pills |
Do not take more than this in a 24-hour period | 12 pills (3900 milligrams) | 8 pills (4000 milligrams) | 6 pills (3900 milligrams) |
Symptoms of Acetaminophen poisoning
Per Merck Manual, overdose develops in four stages. (Organ functioning can be determined using blood tests.)
After a few hours of overdosing: The individual may vomit or have no symptoms.
After one to three days: Individual suffers from nausea, vomiting, abdominal pain and poor liver functioning.
After three to four days: Vomiting, poor liver functioning, jaundice and bleeding occurs. If severe, the individual might have pancreatitis and the beginning of kidney failure.
After five days: Recovery or death if the liver and other organs fail.
Non-steroidal anti-inflammatory drugs (NSAIDs)
NSAIDs treat pain, fever and inflammation. Common NSAIDS include aspirin, naproxen sodium (Aleve) and ibuprofen (Advil, Motrin), per the National Library of Medicine.
NSAIDs can lead to unwanted side effects such as dizziness, high blood pressure and stomach irritation, according to Better Health.

What can affect pain reliever safety?
Different conditions can affect how much or what type of pain medication you should use. Consider talking to your doctor if you have, do or worry about any of the following, per WebMD:
Age and weight: The less you weigh, the less you should take. Typically, children and teens should not take aspirin. Read the bottle label to learn more.
Alcohol use: Do not drink near or around the time during use. Read the label for specifics.
Stomachs: The more NSAIDs you take, the more irritation in your gut and stomach occur. Take a low dose with food if you are worried.
High blood pressure: Some medications raise blood pressure. Acetaminophen might be best.
Kidney disease or similar problems: Kidney damage may occur with NSAIDs.
Liver problems: Avoid NSAIDs and take acetaminophen in small doses.
Pregnancy: NSAIDs are not recommended.
Other medications you are taking: Some drug interactions are life threatening. Tell your doctor what other supplements and medications you are taking.
