供买不到退热药的参考

由于Covid-19 omicron，不少人发烧没有解热镇痛药。美国市场主要有Tylenol 和Ibuprofen 即泰诺和布洛芬。

上述药若买不到其它相似产品可以代替。自己找一下列出如下的中文名，按图索骥。

泰诺不是非激素类解热抗炎镇痛类。注意肝功。

布洛芬则是非激素类解热抗炎镇痛类。注意肾功。

Acetaminophen (Tylenol泰诺) is known as a non-aspirin pain reliever. It is NOT an NSAID, which is described below. Acetaminophen relieves fever and headaches, and other common aches and pains. It does not relieve inflammation.

The main types of NSAIDs include:主要的非激素解热抗炎镇痛药如下：
ibuprofen（布洛芬）
naproxen（萘普生）
diclofenac（扶他林、待克菲那、服他灵）
celecoxib（塞来昔布、西乐葆）
mefenamic acid（甲酚那酸、朴湿痛）
etoricoxib（依托考昔）
indomethacin（吲哚美辛）
aspirin （阿斯匹林）for pain relief (low-dose aspirin is not normally considered to be an NSAID)

The main mechanism of action of NSAIDs is the inhibition of the enzyme cyclooxygenase (COX). Cyclooxygenase is required to convert arachidonic acid into thromboxanes, prostaglandins, and prostacyclins. The therapeutic effects of NSAIDs

When possible, NSAIDs should be avoided in persons with preexisting renal disease, congestive heart failure, or cirrhosis to prevent acute renal failure. Care should be used when prescribing NSAIDs in persons with an increased risk of renal complications.

Possible side effects of NSAIDs include:
indigestion – including stomach aches, feeling sick and diarrhoea.
stomach ulcers – these can cause internal bleeding and anaemia; extra medicine to protect your stomach may be prescribed to help reduce this risk.
headaches.
drowsiness.
dizziness.
allergic reactions.

FDA recommends avoiding use of NSAIDs in pregnancy at 20 weeks or later because they can result in low amniotic fluid. Welcome to the FDA Drug Safety Podcast for health care professionals from the Division of Drug Information.
