This useful medicine can be classified under the label NSAIDs, or non-steroidal anti-inflammatory drugs. Annually, people consume approximately about 40,000 metric tons of aspirin worldwide. Throughout the years, this drug has been proven safe and effective for treating mild to moderate levels of pain such as fever and migraines.
