NSAIDs are available over the counter in low doses, or by a doctor's prescription in higher potencies. Some examples of NSAIDs include ibuprofin, naproxen sodium and aspirin. Common side effects of NSAIDs include stomach pain and constipation.
NSAIDs may be used to control chronic pain, or may be used along with other pain medications (such as opioids or adjuvant analgesics) in the treatment of breakthrough pain.
