Question
I received the diphtheria vaccine at 9 AM on Saturday and started to have a fever at 10 PM that night. After taking fever-reducing medication, the fever subsided, but it came back a few hours later. This pattern has continued for two days. I also noticed that drinking warm water can bring down the fever. Is this a reaction to the diphtheria vaccine? I’ve been sweating a lot during sleep last night, but I didn’t have a fever.
Answer
Based on your description, if there are no other discomforts or abnormalities, it can be considered a fever reaction after vaccination. A detailed examination should be conducted to determine the specific situation, and active treatment should be pursued. Such cases are usually not serious and can be treated symptomatically. It’s important to maintain a proper diet and strengthen care, avoiding adverse stimuli. If the fever is too high, medications like Anruike can be used to alleviate symptoms, which is usually effective. Please follow the guidance of your clinical doctor. These suggestions are for your reference and hope they are helpful to you. Wishing you good health!
