(HealthDay News) - Non-steroidal anti-inflammatory drugs (NSAIDs) are pain relievers, many of which are available without a doctor's prescription. They include aspirin, ibuprofen and naproxen.

While NSAIDs are safe for most people in recommended doses, the American Academy of Family Physicians says the following people shouldn't take these drugs unless they've consulted a doctor first:

• Anyone who takes a blood-thinning medication.
• Anyone with bleeding in the stomach, intestines or any type of bleeding disorder.
• Anyone who has stomach ulcers.
• Anyone who has liver or kidney disease.
• Anyone who consumes three or more alcoholic drinks per day.
