In general, infectious syphilis refers to the primary and secondary stages because syphilitic chancres, mucous patches, and condylomata lata are highly infectious lesions. Dry rashes, by exception, are typically noninfectious.
It appears to reduce pain primarily in the central nervous system by more than one mechanism, possibly in part by inhibiting a form of COX known as COX-3, although this is the subject of much debate. It is, therefore, considered to be a weak analgesic and does not possess anti-inflammatory properties. What this means to you is that acetaminophen is great for headaches, fever and minor aches and pains, but wonât reduce inflammation due to, say, a muscle sprain.
Over-the-counter medications are good for many types of pain. Acetaminophen (Tylenol) is good for relieving pain and fever. It is less irritating to the stomach than other over-the-counter pain medications and is safer for children. It can, however, be toxic to the liver if you take more than the recommended dose.
