Drug allergy symptoms?

Drug fever. Fever caused by drug allergy is called drug fever, which is often the earliest manifestation of drug allergy. Drug fever is different from general infectious fever. If the drug is used for the first time, fever may occur after a sensitization period of about 10 days; If the drug is used again, fever can occur rapidly because the human body has been sensitized. Drug fever is generally a persistent high fever, often up to 39 degrees, or even more than 40 degrees.

Drug eruption. Drug allergy can often cause skin rash, we call it drug rash. Drug eruption usually follows drug fever, but it can also precede drug fever. The skin rash can have many forms, such as measles, scarlet fever, eczema, urticaria, purpura, herpes, etc.

Serum sickness like reaction. Seropathy is a kind of allergic reaction after about 10 days of using serum preparation for the first time. The clinical manifestations were fever, lymphadenopathy, arthralgia, hepatosplenomegaly, etc.

matters needing attention

Prepare rescue drugs before medication. Even if the drug has never had an allergic reaction, it does not mean that there is no allergic reaction. People with allergic constitution may be allergic to any medicine. Be sure to prepare rescue drugs before medication, such as adrenaline, Nikethamide, dexamethasone, caffeine, oxygen, etc. It's too late to prepare rescue drugs after allergic reaction.
