病人根据指导使用止痛剂是安全和有效的，然而要是使用不当就会对身体有极大的伤害甚至会导致死亡。

　　服用止痛剂必须遵医嘱，不能随意更改用药量。个体之间的差异很大，并不是人人都适用同一个剂量。

　　以下我们分享了一些使用止痛剂的小贴士

　　使用对乙酰氨基酚

　　1.过量使用并不会使症状缓解，而还有可能对机体造成损害;

　　2.使用对乙酰氨基酚类药物与酒精同食，会导致肝脏损伤和坏死;

　　3.婴儿和儿童慎用，用前请遵医嘱。

　　使用非甾体抗炎药(NSAIDS)

　　1.使用过量可导致胃出血，60岁以上老年人由于血管变薄易出血，或是曾经有过胃出血或是溃疡的人更易出血;

　　 2.非甾体抗炎药(NSAIDS)可对肾脏造成负担，60岁以上老人易引起此类疾病和并发症，例如高血压、心脏病或是潜在的肾脏疾病。

　　使用阿片类药物

　　 1.使用阿片类药物可导致人瞌睡，最好不要在开车时服用，第一次服用阿片类药物瞌睡尤为明显;

　　 2.过量有可能致死，尤其是对于儿童。

　　然而，社会上出现了一些误用或滥用止痛剂的情况。在阿片类药物滥用方面尤为明显。由于其是樱粟提取物，有些伪君子会把这个药品当做毒品吸食。由于其不当的操作和用量导致最终的死亡。

　　USE AS DIRECTED

　　Pain medications are safe and effective when used as directed. However, misuse of these products can be extremely harmful and even deadly.

　　Consumers who take pain relief medications must follow their health care professional's instructions carefully. If a measuring tool is provided with your medicine, use it as directed.

　　Do not change the dose of your pain relief medication without talking to your doctor first.

　　Also, pain medications should never be shared with anyone else. Only your health care professional can decide if a prescription pain medication is safe for someone.

　　Here are other key points to remember.

　　With acetaminophen:

　　· Taking a higher dose than recommended will not provide more relief and can be dangerous.

　　· Too much can lead to liver damage and death. Risk for liver damage may be increased in people who drink three or more alcoholic beverages a day while using acetaminophen-containing medicines.

　　· Be cautious when giving acetaminophen to children. Infant drop medications can be significantly stronger than regular children's medications. Read and follow the directions on the label every time you use a medicine. Be sure that your infant is getting the infants' pain formula and your older child is getting the children's pain formula.

　　With NSAIDs:

　　· Too much can cause stomach bleeding. This risk increases in people who are over 60 years of age, are taking prescription blood thinners, are taking steroids, have a history of stomach bleeding or ulcers, and/or have other bleeding problems.

　　· Use of NSAIDs can also cause kidney damage. This risk may increase in people who are over 60 years of age, are taking a diuretic (a drug that increases the excretion of urine), have high blood pressure, heart disease, or pre-existing kidney disease.

　　With opioids:

　　· Use of opioids can lead to drowsiness. Do not drive or use any machinery that may injure you, especially when you first start the medication.

　　· The dose of an opioid pain medication that is safe for you could be high enough to cause an overdose and death in someone else, especially children.
