Does Antibiotics Cause Fever?

Yes, in some cases, antibiotics can cause fever as a side effect. Fever is one of the potential adverse reactions that can occur when taking antibiotics, although it’s not very common. Antibiotics work by targeting and killing bacteria that are causing an infection. During this process, they can release certain substances from the bacteria, known as endotoxins, which can trigger an immune response in the body. This immune response can sometimes lead to fever.

However, it’s important to note that fever while taking antibiotics could also be a sign of other issues, such as an allergic reaction to the antibiotic, an underlying infection that the antibiotic isn’t effectively treating, or a separate medical condition. If you experience a fever while taking antibiotics, it’s recommended to contact your healthcare provider to determine the cause and appropriate course of action.
