Shop assistant: Hello! Can I help you？
Potential customer: Do you have indomethacin？
Shop assistant: Yes, is itfor you？
Potential customer: Yes. I have migraine. It''s very painful, and Ihave to take an indomethacin tablet when I suffer an attack.
Shop assistant: Analgesics bring relief. But they also have seriousside effects if taken over a long period.So one should not take them withouta doctor''s advice. I heard that a woman suffered renal damage after takinganalgesics in large doses to treat her migraine pain. She lost a lot ofweight, suffered a nonnasal inflammation and had pain in her joints. Besides, she passed urine more than a normal human, with the problem becomingespecially serious at night.
Potential customer: It''s terrible! Can the side effects be even moreserious？
Shop assistant: There are three types of analgesics, each used in different situations. One is anti-inflammatory and ant rheumatic, suchas aspirin, indomethacin, phenylbutazone and acetaminophen, which are not so strong. Although addicted is rare, their misuse could harm a person. The other type is centrum analgesic，such as tramadol - medicines of artificial synthesis - used to relieve the pain after a surgery. It''s classified as non-narcotic analgesic because its mechanism different from opioids, or opium-based medicines. The last type is narcotic analgesicssuch as morphines and pethidines, which are strong medicines, and a person could getaddicted to them if he takes them repeatedly.
Potential customer: Well, I think I''d better go to a hospital to seek a doctor''s advice.
Shop assistant: Wish you a fast relief from your migraine. Bye!
Potential customer: Thank you! Bye! （赵喜君 华铮 王立峰）
